Interview with Professor Yanlin Zhao

Introduction

We often encounter problems in the course of our experiments that cannot be solved by our team members' discussions, so our team keeps a wide open-minded and inquisitive attitude. Seeking help from some experts and scholars can further expand the team experiments and get more novel ideas at the same time.

Communication

Prof. Yanlin Zhao is mainly engaged in marine microbial ecology research, and conducts microbial genomics and comparative genomics research with marine dominant bacteria and phages of great ecological significance.

Considering Professor Zhao's area of expertise, we also targeted some questions. Prof. Zhao pointed out that besides purifying the seawater environment and assistant marine carbon balance, we also need to pay attention to the conservation of marine diversity. Therefore, we also consider the fixation of algae strains in the design of the laboratory to prevent them from spreading in the water column and causing pollution. Prof. Yanlin Zhao also gave us valuable advice on the genetic recombination of Trichoderma reesei. Prof. Zhao mentioned that we must consider all possibilities when designing experiments, which is a great inspiration for our experiments. Considering the possibility of accidental infection, we will do more biological replicates and repeat sterilization during the operation. When the results of several experiments are inconsistent, we will review the literature to see if the protocol needs to be changed. In the recombinant lab we usually design several protocols to avoid unexpected effects on the results. At the same time, she gave great recognition to our project, "These microorganisms have a huge number and diversity, and what researchers know about them now is just the tip of the iceberg, and it is very meaningful to keep discovering and exploring the value of using microalgae in research to apply them in real life."

Aid

"The burden of cultivating a new generation of young talents is not easy, and I often reflect on myself: what do students need? How to guide students well? Is the guidance adequate?" In Prof. Yanlin Zhao's view, the primary responsibility as a graduate student mentor is to guide students well, provide them with a platform for research, and stimulate their creative ideas. She always hopes to spare more time to guide students and promote joint progress. When students encounter difficulties in their experiments, she will work with them to find the reasons for their failures, trace every step and process of the experiment, and find solutions to problems from analyzing the source. Prof. Zhao's words also inspired our team to be more creative and to stimulate their interest in learning when the project reaches out to people of all levels. In the subsequent "Blue Carbon" sessions, time was set aside for students to ask questions and organize craft activities to generate interest.

Vision

With the industrialization of cities and the improvement of people's living standards, more and more domestic and industrial wastewater is generated. The traditional wastewater treatment process turns the organic carbon and ammonia nitrogen in the wastewater into carbon dioxide and nitrogen gas to the atmosphere through massive aeration and alternating anaerobic and aerobic operation, without recycling in the form of energy or resources. With the depletion of fossil energy and the increasing greenhouse effect, the search for more energy-efficient and environmentally friendly wastewater treatment processes has become very urgent. We hope that Brown Finger Algae Triangle will soon be applied as an effective product for wastewater treatment at a low cost.


Interview with Professor Rensen Zeng

Communication

We introduced our project principle to president Zeng in the form of a PowerPoint presentation, which intends to use Phaeodactylum tricornutum with multiple iterations of PTCA and other genes to sequester carbon to slow down global warming. We also aim to improve the ability of microalgae to adsorb heavy metal elements to solve the problem of excessive sewage discharge. President Zeng believes that algae are a good entry point to mitigate climate change, as they do not take up arable land and are not harmful to the ecosystem, but it is worth noting how to fix and apply this tiny organism. In response to this currently unsolved problem of algae fixation, President Zeng gave us new ideas. He pointed out that the algal spheres might block the material flow and that muddy materials might be a better choice. The team members also said they would try more here.

In addition, we showed Principal Zeng the activities that the team has already held in the education section, such as environmental walk, tri-

fold distribution, etc. Principal Zeng gave us high praise and said that this is a field worth exploring, which is full of opportunities and possibilities despite the treacherous road.

Unique Advice

President Zeng pointed out that our PPT was not clear enough and that we could use the carbon and nitrogen cycle diagrams to analyze the links with high emissions to design experiments more realistically, and we could use videos or animations to explain the project process more clearly and intuitively. When reporting the results, we can also use diagrams to express the purification effect of Phaeodactylum tricornutum.

Project Impact

The affirmation from Principal Zeng gave the team confidence that our efforts would allow more audiences of all ages to learn about this algae that does not take up arable land and produces high value by-products. It also provided us with new ideas for our project presentation, learning a new way of visualizing and persuading the cycle diagram.


Interview with CEO Jinjian Xie of Fujian Shenliu Group

Introducation

Many iGEM projects can eventually be put into actual production applications, especially for us who eventually want to put the technology into practice. To move to actual production based on the theoretical basis of the laboratory, this is definitely not enough for the experiments done in the laboratory, which involves other factors such as economic interests, production efficiency, social needs and so on. And there are many processes and difficulties that we don't understand. That means we need to talk to a business that is actually going into production. There is a company in our local area, Fujian Shenliu Group, which has researched on the production and application of spirulina. On July 3, we decided to go to Fujian Shenliu Group to conduct research and interview Xie Jinjian, the person in charge of the group, in order to understand the company's understanding of pollution control technology and its opinions on microalgae treatment technology. Through this interview and communication, we have learned about the company's views on advanced sewage treatment methods and the development status of local pillar industries, have a deeper understanding of the application of project technology, and have also promoted the practical application of our technology.

Pollution Control Cost

Since Fujian Shenliu Group has researched on the production and application of spirulina, we have raised questions about the company's current technical or cost difficulties in treating sewage. We believe that at the technical level, the use of microalgae to treat wastewater is an ecologically sustainable technical method, which can absorb and degrade pollutants in wastewater by exerting the synergistic effect of algae and bacteria. The entire treatment process is not only low in energy consumption, but also promotes the recycling of nutrients such as nitrogen and phosphorus, and at the same time achieve the purpose of controlling greenhouse gas emissions. At the cost level, we believe that the techno-economics are not recognized, so it is necessary to carry out comprehensive development to improve the sustainability of the technology and reduce the cost, and we also consider that the environmental risks are also to be further evaluated. In general, large-scale production and utilization of microalgae remains a technical challenge. Accordingly, Xie Jinjian replied: Different treatment processes will produce different operating effects, and operating costs will also be different. Large-scale sewage treatment plants mostly use traditional activated sludge method and its deformation process, while small-scale sewage treatment plants mostly use oxidation ditch process. However, he believes that microalgae wastewater treatment technology is a green technology with great potential and has broad market prospects. We need to investigate new microalgae wastewater treatment processes from the aspects of pollutant treatment efficiency, process energy requirements and economics, pay attention to product development of algae, propose sustainable treatment technologies, and promote wider application of microalgae wastewater treatment. This may be related to the fact that most of the wastewater treatment technology with microalgae stays in the laboratory stage. For Shenliu Group, the annual expenditure on wastewater treatment is a large amount. Therefore, they do not know much about the cutting-edge sewage treatment technology.

School-Enterprise Cooperation

We also raised the question of where to start our research projects if we want to cooperate with companies. Because our project is currently progressing slowly in cooperation with enterprises, in this regard, we would like to have practical cooperation with Fujian Shenliu Group Company. Fortunately, Xie Jinjian believes that school-enterprise cooperation and the combination of production and education are good ways. He said frankly that he hopes to achieve resource sharing and win-win by establishing a work-study practice base. Let the advanced corporate culture enter the campus, enterprise management into the classroom, production management into the base, in this way to help improve the quality of talent training. It is reported that Fujian Shenliu Group has achieved remarkable results in talent training through several years of school-enterprise cooperation, and team members have also gained a deeper understanding of the company's culture through this exchange and practice exchange to promote the actual promotion of our project.

Project Impact

Through this communication with the company, we learned a new observation angle. From the market point of view, it is necessary to investigate the new microalgae wastewater treatment process from the aspects of pollutant treatment efficiency, process energy consumption and engineering economy. In particular, we should pay attention to the product development of microalgae, propose a sustainable development route based on the concept of circular economy, and use the microalgae treatment wastewater technology as the source rather than the terminal of the microalgae product development process, so as to promote the wider application of microalgae wastewater treatment. President Xie Jinjian's introduction to the historical development of Shenliu Group also made us understand the company's views on sewage treatment methods and the development status of local pillar industries, and gained a new understanding of the sewage treatment work carried out in this project.

Reflect and Further Improve

We are very grateful to have this opportunity to interview the president of Fujian Shenliu Group Xie Jinjian while conducting on-the-spot investigation of Fujian Shenliu Group. Throughout the year, we encourage dialogue with different groups, as we hope to measure the practical significance of our projects. Regarding the suggestion given to us by President Xie Jinjian, we have determined that if we have the opportunity to personally go to the enterprise to practice, the practical application of the project will be greatly improved.


Interview with Government Officials of Yangkou Town

Introduction

Yangkou Town, located in Shunchang County, Nanping City, has a history of more than a thousand years. Currently, is now recycling excrement jointly with enterprises to obtain more additional production value and promote zero-carbon industries. Huang Naigan, Minister of Yangkou Town Government, is an expert in applying environmental governance to practice. We were inspired by the story of the governance environment he conveyed, and his efforts to capture the audience's attention, so we decided to reach out to him for their feedback on the way we present our projects. We hope that through this interview, we can learn about the measures the local government has taken on the governance of the rural ecological environment, so that we can better understand what publicity we need to do to contribute to raising the public's awareness of environmental protection.

Interview with Mr. Huang Naigan

In July this year, we interviewed Mr. Huang Naigan, Minister of the Armed Forces of Yangkou Town, Nanping City, at the Yangkou Town Government. The subject of this interview is mainly about how Yuyangkou Town has taken the zero-carbon Shunchang concept as its foothold and realizes a series of innovative measures such as environmental governance and ecological protection. As far as we know, Shunchang County has been working hard for rural environmental governance in recent years. Huang Naigan also proposed: In order to implement the zero-carbon Shunchang concept. Yangkou Town's work on ecological governance has been implemented in all aspects of life, starting from the management of rural domestic waste and in accordance with "reduction first, encourage classification, urban and rural overall planning, and comprehensive management". Our team also thought of this in advance, so we put forward more in-depth discussions on the rural governance environment. After learning about our project, Mr. Huang Naigan now expresses his affirmation. He said that in the early stage of treatment, we were very troubled with sewage treatment. Many villagers would wash clothes by the creek, but the water quality was poor. It took a lot of energy and material resources. He said that our project can, to a certain extent, conduct popular science on water control for the masses. It can be seen from our active discussions on site that the government is very concerned about this aspect. During our communication, we talked about the need to strictly implement a series of measures such as the implementation of the management system in order to control the rural water environment.

Project Impact

We not only exchanged our experience in rural environmental governance with him, but he also gave positive comments on our educational activities over the past year. The focus is on popular science education for people in underdeveloped areas, and we take into account the scientific and environmental aspects of the project, as well as privacy. In his opinion, our interesting popular science propaganda has caught his attention. Regarding the method of popular science education, he strongly suggested that we use the form of art to popularize some incomprehensible synthetic biology knowledge. All in all, this interview brought fun to everyone and gave us new ideas on how to conduct educational activities.

Vision

First of all, thank you very much for having this opportunity to communicate with Mr. Huang Naigan. In this interview, we learned about Mr. Huang Naigan's measures to manage the rural environment. At the same time, our team also thought about how to apply our technology to less developed areas. , so we have a new direction, we hope to control the cost of our technology and the acceptance of new technology by people in underdeveloped areas as much as possible. This has promoted the progress of the project, and we have also been affirmed by Mr. Huang Naigan. We are very grateful for the project ideas he provided, and he also led us to understand the relevant policies, which is of great significance for us to put the laboratory results into practical production applications.


Communication with Professor Lin Wenxiong:

Surely and Support

We encounter some difficulties at the beginning of our project. Professor Lin Wenxiong helped us a lot when we were looking for a new way out. We made a hardware model , but it was difficult to be used widely, because of the cost. Professor Lin told us that the products we made may not currently make great economic profits in the market, but as long as the products are valuable and can help achieve carbon neutrality, it is a valuable product, and in the future we can continue to carefully study ways to reduce cost. In addition, in the education section, we have planned to enter the campus to lecture and hold academic exchanges , but the forms are rather limited and not interesting enough, and we are worried that it will be difficult to attract public attention. After hearing this, Professor Lin first affirmed that our idea was scientific and he expressed his willingness to help us b class="fcolor"> call on the public to pay attention to the water environment management problem. This gave us great encouragement and confidence.

Unique Advice

We were worried that the format of campus lectures and academic lectures were rather rigid and can not effectively shorten the distance between scientific communication with the public. Professor Lin gave us an easy-to-understand example: when watching the cartoons when I was a child, I still remember the characters very clearly. Why is this? Because the animation or cartoon cartoonizes the boring stories, and the interesting conversations make it easier for us to remember. Therefore, when carrying out education and publicity, more scientific knowledge can be personification, which is more conducive to the dissemination. This suggestion helped us open our minds, and we also listened to Professor Lin's advice, and made special hand-painted books to support the reading from primary school to college, and even for adults.

Project Impact

After we finished making the science book and hand-painted book, we contacted Professor Lin to get some guidance and suggestions. Professor Lin admired our science book and hand-drawn book while flipping through them and reaffirmed our approach. After reading them carefully, Professor Lin suggested some changes on the framework to help us further improve the book content, which helped us a lot.

In short, the communication with Lin Wenxiong promoted the progress of the project, and we also got the idea to solve the problem. At the same time, we are very grateful to Professor Lin Wenxiong for his support and encouragement to our project, which is of great significance to put the laboratory results into practical production and application.


Interview with the Head of Fuzhou Jinshan Wastewater Plant

Introduction

In a meeting summary, one of the team members mentioned that we should go to the field to study the wastewater plant further understand the mainstream of the current market for wastewater treatment, and to find some inspiration for our team project. After tcommunication, we contacted the person in charge of the Jinshan sewage plant, who agreed to visit the plant and answer our questions The person in charge told us that the drainage system of Jinshan Wastewater Plant adopts a split flow system, and adopts a modified process of SBR - ICEAS wastewater treatment process , using the depth treatment process of " high efficiency sedimentation + filter cloth filter tank ", and the wastewater treatment reaches the standard of "urban wastewater treatment plant pollutant discharge standard" in Table 1 of Class A. After the initial understanding, we also told the person in charge of the principle and method of microalgae treatment of sewage. Microalgae have certain treatment effect on harmful sewage containing pesticides, antibiotics, heavy metals, etc., and have the effect of adsorbing toxic and harmful substances such as heavy metals within a certain concentration range. Our project is to modify the ability of microalgae to absorb N and P elements through transgenic technology and play a greater role in sewage treatment. He appreciated our project and mentioned that most of the wastewater plants have not yet used microalgae to treat wastewater, which is mainly due to the fear of high cost, unknown risks of the new technology, etc.

Government's Concern

According to the United Nations Sustainable Development Goal No. 6: Everyone should have the right to clean drinking water and water use, in order to ensure that more people understand the knowledge related to water conservation, water love and water protection, and to raise good awareness of resource conservation, our government has also formulated relevant policies to monitor the sewage data testing of factories, enterprises, sewage plants, etc., and adopted a transparent and open system so that the public has the right to know what social institutions have to say about sewage treatment programs. This will help to improve the quality of life of people and the natural ecological environment.

Help Received

Although the Jinshan sewage plant does not use the technology of microalgae to treat the sewage, the person in charge knows something about the method of microalgae treatment of sewage. After communication, he told us that pesticides, antibiotics, etc. can be degraded or adsorbed within the tolerance limit of microalgae. This point gave us a direction to think about, and for the adsorbed algae, we plan to study it again later to achieve pollution-free treatment through thermal cracking and other forms to further improve the project's treatment system.


Unexpected Effect

Marine pollution and fashion aesthetics, two seemingly unrelated things, collided in a wonderful way. Starting from a bold idea, we unexpectedly found that a fashion show with elements of marine pollution prevention could be a novel and more noticeable way to raise awareness among the public.

Publicity of Marine Protection:

We found through the survey that most of the public do not know much about marine ecology, marine economy, marine science and technology, marine livelihood and other fields of knowledge, nor do they know much about the current series of crises facing marine ecology. In such a situation science education work is particularly important. We believe that if we can make the public know the ocean and care about it, we can further promote the formation of a good social atmosphere for all people to care for the marine environment. With this in mind, we contacted the DAMO Dandelion organization to promote the success of this event.

Children and Fashion Shows

Most children do not like to be taught recondite science knowledge, instead, some fun and innovative activities incorporate knowledge that they can remember and reflect in real life. This is the basis for the collision of "children" and "fashion shows". Most people in the world do not have a knowledge base, but it is necessary to make them aware of it.If the majority of the world's population is fully aware of the ecological crisis the oceans are facing, some of them will take action, which will add a strong force for ocean conservation in the world and will greatly improve the current state of the marine environment! And children are the group that is forming the conceptual consciousness, education during this period can make them develop the consciousness of protecting the marine ecology and caring the earth's environment at an early age, and may lead them to the path of protecting the earth's environment in the future!

Carefully Prepared Activities

A number of mannequins were set up in the studio where the materials for making the costumes were prepared. The children expressed their sense of the sea by drawing pictures, and the professional costume makers then made the finished clothes according to the elements designed by the children and their figures. The stage was decorated to imitate the simplicity of a fashion show, and a carpet was set up in the middle to give the children a chance to express themselves. This preparation was a great success, and the audience was deeply impressed by the children's designs, and there was a constant roar of approval from the audience.

Adequate Communication

During the children's design process, we talked to them about some basic information about the ocean, including plastic pollution, the endangerment of some marine species, the serious pollution of the marine environment by human waste, etc., to help them better understand the theme of marine pollution, and then let the children design more meaningful works based on this background knowledge.

An unexpected surprise: in the clothing design class, the children were more serious about designing clothing patterns, fabrics, etc. than originally expected - the work created by the children was very creative, flexible and vivid.

Wonderful Fashion Show

We have been thinking that the way of promoting marine conservation should not just be limited to the listening format of knowledge lectures and mass communication sessions. We adopted a brainstorming approach and finally settled on a new plan: to hold a special, interesting and innovative fashion show! We contacted the organization Daimo Dandelion to co-organize a fashion show with the theme of ocean conservation.The participants of the fashion show were mainly children, who brought out the unique childishness and creativity of this age group, and finally presented a wonderful fashion show stage! Ocean pollution is a heavy topic, and this event perfectly solved the difficulty of spreading knowledge and brought children to think about ocean pollution in a visual and more impressive way.

Parents' Appreciation and Insight

Most of the parents didn't expect their children to be so creative, and they were shocked by how wonderful the fashion show was! During our conversations with parents, we told them how smart and creative children are. We also saw the children's parents as the target audience and we distributed pamphlets about ocean conservation to them. We told the parents that the ocean ecosystem is one of the most important ecosystems in the world, affecting the stability and security stability and security

Interview with Professor Qiang Wang

Our Premise

On September 29th of this year, we conducted an interview with Prof. Qiang Wang after the Chinese Society of Plant Physiology and Molecular Biology. We benefited a lot from this activity, and through the professor's guidance, we also understood the future plan and prospect of the project development, which is very meaningful.

Serious inquiries and rigorous answers

In this process, we firstly introduced the composition of our team and and the role of each classification to Prof. Wang Qiang. The professor listened carefully to the composition of our team and gave us some suggestions, such as the appropriate division of labor in the team. We also learned that Prof. Wang's research interests are mainly in algal biology, photosynthetic environmental stress response and synthetic biology. We also learned that Prof. Wang's research is focused on photosynthesis, environmental stress response and synthetic biology, and that he has taken photosynthesis research model materials, cyanobacteria and Chlorella, as the research objects, based on photosynthesis and synthetic biology, focusing on environmental problems, and conducting systematic research around scientific problems such as microalgae environmental adaptation, bioenergy and bioreduction, which is closely related to our subject direction and research direction.

Then we introduced our team's research direction to Prof. Wang Qiang, the feasibility of microalgae for wastewater treatment and the feasibility of extracting the high economic value products Phaeodactylum tricornutum,EPA and biodiesel from microalgae for wastewater treatment, Prof. as the research objects, based on photosynthesis and synthetic biology, focusing on environmental problems, and conducting systematic research around scientific problems such as microalgae environmental adaptation, bioenergy and bioreduction, which is closely related to our subject direction and research direction. Then we introduced our team's research direction to Prof. Wang Qiang, the feasibility of microalgae for wastewater treatment and the feasibility of extracting the high economic value products Phaeodactylum tricornutum,EPA and biodiesel from microalgae for wastewater treatment, Prof. Wang Qiang spoke highly of our ideas and gave full affirmation to our ideas, he explained to us that microalgae have fast growth rate, high CO2 fixation efficiency and He explained to us that microalgae have high growth rate, high efficiency of carbon dioxide fixation and photosynthesis, and can absorb and degrade the pollutants in the sewage during the growth process, thus playing a role in purifying the water. In addition, the application of microalgae in wastewater treatment has the following advantages: the use of microalgae biomass for fertilizer production, the recovery of assimilated nitrogen and phosphorus, and the resulting microalgae biomass can be used for the production of biofuels, functional foods, animal feed and pharmaceuticals, etc. In addition, microalgae reoxygenate wastewater through photosynthesis. Based on these advantages, more and more researchers are focusing on the use of microalgae to treat wastewater, leading to the rapid development of this technology and its gradual move towards practical engineering applications. We asked the professor about the advantages of microalgae treatment of sewage and feasible methods, and Professor Wang Qiang explained to us, "Microalgae assimilate and absorb pollutants such as nitrogen, phosphorus, heavy metals and organic matter in sewage during the growth process to purify the water, which greatly reduces the treatment cost and the chance of secondary pollution compared with physical-chemical methods. In future work, the focus should be on the practical application of microalgae treatment of wastewater and biomass production coupling technology to fully exploit the economic potential and environmental benefits of microalgae.

However, there are still some technical problems to be solved for the industrialization of this technology. Firstly, it is necessary to domesticate and screen high quality algae species that effectively purify water and select those with high content of oil or bioactive substances. Secondly, an economical and efficient technology for separating and harvesting microalgae should be developed. Finally, a light reactor suitable for the growth of microalgae and which can be operated on a large scale should be developed."

Wishes and Prospects

At the end of the interview, we had a group photo with Prof. Wang Qiang. The use of microalgae to treat wastewater provides an environmentally friendly path to alleviate water pollution. It is believed that with the development and breakthrough of technology, the water purification and biomass production coupling technology based on microalgae culture will have a broader prospect in the future when the shortage of resources and energy is becoming increasingly severe.


iGEM Teamwork-CCiC Conference

Introduction

In the face of all communication, the quickest way to get effective information is none other than face-to-face consultation and discussion. We have noticed that in recent years, the frequency of iGEM teams conducting external events to promote their projects is increasing, as are the opportunities for team-to-team communication. For teams in China, participation in the CCiC community is a key opportunity for good communication and cooperation with other teams. For this reason, we actively participated in the conference and hope to introduce our project to iGEMers, as well as listen to participants' project descriptions and gain more information about synthetic biology.

The Theme of "Life Meets Everything"

Due to the epidemic caused by the new coronavirus, this year's CCiC will take place from August 18 to August 22, 2022, in a combination of online and offline formats. The conference was hosted by the University of Shanghai for Science and Technology team and attracted more than 1000 iGEMers. The theme of this year's conference is "Life Meets Everything", which aims to encourage everyone to explore and think about more paths to use synthetic biology for practical applications, to aspire to life, and to contribute to the future. This is also one of the common goals of all human development.

A Comprehensive Perspective of Discussion

In this year's conference, the organizers set up six lectures on synthetic biology, and invited many experts in the academic field to participate in the conference and introduce their research fields and the current status of their research one by one. At the same time, the conference also enabled each team to present their project content in the form of poster show and slide show. After the team leaders finished their presentations, the judges and the audience could ask them questions to enhance the interactivity and make the leaders aware of the problems and omissions of their projects. It is also important for each team member to fully condense their ideas when presenting to avoid taking too long. Posters and slides improve the audience's understanding of the project and allow the content to be expressed clearly enough, which is certainly helpful for the presentation; and the joint delivery of the presentation and the oral presentation is a great opportunity for different teams to learn from each other.

Vision

The CCiC Conference hopes to create a good atmosphere and a platform for teams to communicate through such a formal discussion format. Such a networking opportunity has brought together most of the iGEMers and biology enthusiasts in China to work together for the development of biology and cutting-edge technology. Likewise, by participating in the conference, we learned a lot of practical skills and knowledge from various aspects of experimentation, human practice, modeling, etc. CCIC built an immensely strong bridge to connect teams with teams in a real way. We hope that we all gained something from the conference and witnessed the budding and development of synthetic biology in China together. And these precious and joyful moments deserve to be recorded.


Interviews with Experts: Including Professors from the School of Public Health, CDC Staff, and River Coast Researchers

Conference Background

On September 17, we conducted an online meeting with Guangxi University GXU-China and Nanjing Foreign Language School Nanjing_NFLS to interview experts together. At the same time, we formed the Fresh Freshwater Bioremediation Alliance (FBA). We jointly invited Professor Shen Xia from Nanjing Academy of Water Resources and asked him questions about wastewater management.

Conference in progress

During the meeting, we asked Prof. Shen Xia about the governmental and private aspects of wastewater management, and she explained to us critically the channels and methods of wastewater management. Then, she introduced to us in detail the methods of sewage treatment, i.e. through physical, chemical and biological methods. The application of engineering bacteria is the biological method, in fact, it has two major advantages, first of all, it is a relatively low cost and no secondary pollution. In our national water treatment, including the treatment of sewage treatment plants, as well as the treatment of natural water bodies, all include the application of microorganisms. At the same time, Prof. Shen Xia also taught us the method of microbial treatment and the feasibility of machine treatment of sewage. We also consulted Prof. Shen Xia about our project - about the feasibility of microalgae treatment of sewage, and the professor fully affirmed the authenticity and feasibility of our project after understanding it, and encouraged us to continue our efforts towards the research direction.

Wishes and Prospects

At the end of the meeting, FBA had a relevant discussion, we deeply understood the current situation of sewage pollution and treatment, we gathered together to discuss each team's treatment and solution for sewage, and understood the situation of each of them. We each provided suggestions and plans for each other's development, which were approved and supported by everyone. With the development of science, the progress of the times, and the rapid growth of population, the water resources on which human beings depend are polluted and the amount of water we can drink and use is unknowingly decreasing. The issue of water recycling is gradually receiving widespread attention from the society, and the solution of a series of problems such as eutrophication of water bodies, excessive bacterial content and harmful residues is imminent. In implementing the 17 sustainability goals proposed by the United Nations, we also discussed the feasibility of microalgae treatment of wastewater technology in practical production applications in this conference, which provides experimental ideas for the laboratory and is of great significance for putting the laboratory results into practical production applications.
