How to realize efficient recycling of industrial wastewater?

Secondly, we should strengthen technological research and demonstration. Liu Guohua suggested that through the national science and technology innovation plan and other funding channels, support the research and development of efficient and low-cost treatment and reuse technology and equipment of industrial wastewater in different industries, in order to meet standards, and actively promote the demonstration and promotion of application in relevant industries.

Third, we should establish and improve the mechanism, incentive and guidance. Liu Guohua said that enterprises in typical industries that actively implement the recycling and transformation of industrial wastewater should be inclined in terms of tax policies and financial support, and enterprises in typical industries should be guided by incentive measures to actively implement water-saving transformation and wastewater recycling.

"Finally, in the process of promoting the recycling of industrial wastewater, it is necessary to strengthen the coordination function of the government, consolidate the responsibilities of departments at all levels, and play a good role in supervision and guidance." Adopt various forms of publicity to promote the participation of all sectors of society and enhance the enthusiasm of enterprises." Liu Guohua stressed.

How to break through the key core technology bottleneck through technological innovation?

The plan emphasizes the steady promotion of wastewater recycling technology transformation and upgrading, and the promotion of 100 advanced and applicable industrial wastewater recycling technology and equipment by 2025.

"The main driving force for the improvement of the recycling rate of industrial wastewater is the key core technology of various typical industries, strengthen the research of advanced technology and equipment, so that the wastewater can be standardized after treatment, and truly used for enterprise production." Liu Guohua said that during the "14th Five-Year Plan" period and even a longer period of time, we need to effectively promote the recycling of industrial wastewater by strengthening key technological research.

So, how to strengthen the key core technology research? Liu Guohua said that first of all, we should do a good job in the top-level design and planning of industrial wastewater recycling technology, deploy through national science and technology major projects, key research and development programs, and strengthen independent research and development; Secondly, the establishment of industry-university-research collaborative innovation model and mechanism, with industrial enterprises as the main body, jointly with the scientific and technological strength of high-level universities and research institutes, or training the research and development strength of scientific and technological enterprises to carry out key technology research, collaborative promotion, and promote the sound development of "promoting research with production and assisting production" in the field of industrial wastewater recycling; Finally, we should actively carry out international cooperation and exchanges, learn from and assimilate foreign advanced technologies, and enhance our independent innovation ability and international competitiveness.

Technological innovation is the main way to solve the key core technology of efficient recycling of industrial wastewater in China. Liu Guohua cited membrane separation, advanced oxidation, concentration and desalination, anaerobic biological nitrogen removal and other technologies as examples, which are the key core technologies for the recycling of industrial wastewater, but there are still many shortcomings, leading to the problems of high cost and low efficiency in the recycling process of industrial wastewater. Therefore, breaking through these key core technical bottlenecks through technological innovation can effectively help improve the recycling rate of industrial wastewater.

"It should be noted that the key core technologies of membrane separation, advanced oxidation, desalination and other industrial wastewater recycling are difficult to make breakthroughs in a short period of time, and it is necessary to actively support the research of these key technologies through various channels, and follow the law of scientific research, and can not be rushed." Liu Guohua said.
