Many people may think that I am a "halfway monk". In fact, when I am an undergraduate or graduate student or even a doctor, there are great differences in the study and research of the subject, both in terms of methods and horizons. After selecting a topic, how to lead undergraduate and graduate students to carry out work and obtain research results is the growth that is really different from others after continuous improvement in academic attainments.

On the road of academic research, it brought me a completely different understanding of my life experience and experience. Although I didn't get anything materially, as a qualified researcher, we think more about what we can do for the country? What can you do for the industry?

Speaking of why I entered the environmental protection industry, this is really a coincidence, because I have started the scientific research and study of membrane since my graduate student. Until I finished my doctor's degree, I began to lead students to carry out the relevant scientific research of membrane.

Just at this time, ruijiete came to me and hoped that I could be the person in charge of membrane product R & D of the company.

At the beginning, I was very tangled. Although membrane also belongs to the chemical industry and I also have the foundation of membrane research, after all, I majored in chemistry, which is equivalent to cross industry. Moreover, there are subdivided fields, such as chemical field, which have many subdivided fields: inorganic chemistry, organic chemistry, analytical chemistry, all chemistry and physical chemistry.

Now more and more scientific research institutes and enterprises begin to cooperate, and entrepreneurial enterprises can better realize the personal value and R & D dream of researchers, so I finally decided to take this job. President pan (Chairman Pan Dingguo) and President Zhou (general manager Zhou Baochang) also continue to give me encouragement and support. And I am loyal to my choice. Since I take this trust, I must overcome all difficulties and try my best to do my best. This is my whole process of entering the environmental protection industry.

Then, with the acceleration of urbanization, domestic sewage caused the spread of infectious diseases through the transmission of bacteria. For health reasons, humans began to treat the discharged domestic sewage.

As early as the late Ming Dynasty, China had sewage purification devices, which were disinfected with lime and alum.

200 years ago, with the development of industry and the increase of human population, water treatment began. In this period, we will temporarily divide it into level 1 water treatment.

With the development of western industry, about 1881, there was secondary water treatment. The ancestor of secondary water treatment was biofilm process. Then, with the development of industry, organic pollution and industrial pollution began to appear. To solve these problems, the process "activated sludge process" we meet every day appeared. In 1914, the world's first activated sludge sewage plant appeared in Britain. Later, due to the improvement of human living standards and the development of industry, processes such as nitrogen and phosphorus removal, anaerobic aerobic, Ao and A2O began to appear. These are activated sludge processes.

Biofilm technology developed again in the 1960s-1970s with the emergence of a large number of new synthetic materials, that is, what we call MBR membrane method. In fact, this method is still activated sludge method, which is now called three-stage treatment process.

To share this story, I want to say that in the process of sewage with human development, there must be technology and chemistry. Water must be treated, and the treatment requirements will be more and more strict. Then we should understand the future development of our MBR.

Activated sludge has been used for 200 years. Our MBR is still based on activated sludge. In fact, the most principle of application is activated sludge. Why use this process? Why not use chemical methods? Why not use other methods? Because only activated sludge is a green process. It uses microorganisms existing on our earth to solve the toxic and harmful substances we make, so I think, It may not be possible to judge how this process is, but we can look at this topic from the historical development trend.

Some people will ask what has been developed after only making one product in ten years? Wrong, wrong. Any company may be able to do what it wants, but the key to the stable operation of the produced membrane is not that it can be achieved in one or two days. The production of a product is either finished or finished. It is necessary to continuously develop and invest in the stability of the membrane. So in fact, ruijiete has done a very solid job in the stability of the actual operation of the products in the initial stage of the first five years.

After 2016, ruijiete began to implement our current integrated equipment, including mini membrane tank, double tower membrane tank, skid mounted membrane tank and Chinese tower tank. The R & D work of the membrane is not just production. Our R & D team has optimized and improved many details through the practical application of the project. Especially the core data of membrane - membrane flux. Our membrane flux is steadily improving. On this basis, we have launched membrane tanks and other equipment.

With the continuous practice of our R & D and application, we have adopted the flux design of 0.46 for the first time in this 30000 ton municipal sewage treatment project, which is a great test of the flux, effluent and product stability of our products in the application of large-scale municipal sewage projects.

Although our products have achieved a relatively high flux for a long time, we have not announced it to the public. This is the requirement of President Zhou. We must never smash our own signboard through the practical application of the project and the feedback of operation data. We will not publicize or do uncertain things in order to win in the industry or focus on the industry, and will not bring any losses to customers.

The project is launched near the end of the year in winter, and the coldest time is about minus 25-6 degrees. Therefore, we pay special attention to the operation and water outlet, and the data are tracked in real time every day. Because the operation is good or bad due to the influence of many factors, such as climate, installation, uneven aeration, exhaust, etc., I put forward suggestions, hold special meetings for operation and train on-site personnel. During the Chinese New Year and the epidemic, meetings are a

The reason why the 30000 ton municipal sewage project is so designed is that our membrane flux is indeed improved. When we do this project, we dare to mention a little more in the design when our products have been operated for one or two years. Therefore, for me, the pressure of this project is the greatest. The operation of a project is not only related to the membrane.

For example: pure water flux and design flux. If the pure water flux is 10, the sewage flux can only be designed to 1, because the sewage is in the sludge. If it needs to be stable in this complex environment, it cannot be the same as the pure water flux. The pure water flux is pollution-free.

Therefore, even if the flux of our membrane is increased by 30%, we still operate according to the original flux in the operation of the project. First, because the quality of our membrane is true, it can only be released after it has been operating stably on the basis of improved flux. Second, the operation of membrane is not only related to membrane, but also affected by many factors. Ruijiete is not only responsible for membrane products, but also responsible for product operation.

Sometimes I keep reading the literature. When new products appear, I have a sense of crisis. I think ruijiete should base on the present, stabilize the present, improve the present quality, and produce new R & D products to move forward. Just now I talked about the development of the sewage treatment industry in the past 200-300 years. In fact, it is very short, from level 1 limestone alum treatment to level 2 activated sludge to level 3 membrane treatment.

Many enterprises, especially physical enterprises, do not keep up with the pulse of the times. When the times abandons you, they will not tell you. Therefore, as the R & D director of ruijiete, I am very anxious to see any new progress in our film in the industry and the new achievements of others in the industry. I think we must work hard and take the lead in ruijiete's existing main products in the industry.

We will continue to launch new products. This new product should be considered from the perspective of users and make more contributions to the future water treatment industry. No matter what industry it is, R & D is the lifeline. Only continuous R & D can promote the continuous progress of the enterprise and the continuous progress of the enterprise.

Moreover, I think China has gone from the stage when there was nothing to deceive just by one mouth during the reform and opening up, especially the environmental protection industry, to a stage where it really depends on facts and does things as a result. Whether it can meet the standard for users is the standard for users to evaluate the company. Moreover, can you really save money for Party A, save money in a more cost-effective way, and save money in operation and maintenance, so as to achieve better processing results for users. These things do not depend on our sales and how much relationship we have with the boss, but on how many technologies and real materials are unique to Ruijie. So R & D is the lifeline of our company.

Taking our company as an example, the first is high-throughput membrane, the second is super hydrophilic membrane, and the third is industry 4.0. We all know that our membrane is a non-standard industry, but if it has been non-standard, it will not be good for our whole industry. How can we apply our industrial modernization to our production? This is the direction we are constantly striving for.
