Sewage treatment and the "double carbon" goal to cooperate, focusing on...

The green development of the industry and the goal of supporting "carbon peak carbon neutrality" is the meaning of the topic. As an important lesson in the green development of the water treatment industry, the utilization of sewage treatment has a high degree of cooperation with the "double carbon" goal.

Since 2020, the word "peak carbon neutrality" has been formally embedded in the background wall of China's environmental green development, requiring carbon dioxide emissions to peak before 2030 and strive to achieve carbon neutrality before 2060. We have to see that the setting of this goal is still urgent and challenging.

At present, the water treatment industry has carried out a lot of research around the "double carbon", such as the efficient operation of water treatment equipment, the improvement of the level of precision work, and the reduction of treatment energy consumption is also the focus of hot discussion.

How can the water treatment industry reduce the pressure of carbon neutrality in the industry, and which of the sewage treatment methods is more "double carbon" heart?

Wang Hongchen, director of the Low Carbon Water Environment Technology Research Center of Renmin University of China, has publicly proposed that the three major carbon emission reduction points of urban drainage and sewage treatment industry in response to the national "double carbon" strategy include: a clear attitude on whether to cancel septic tanks, increase research efforts on nitrous oxide control, and enhance the awareness of the importance of energy conservation and consumption reduction.

In addition, he also mentioned that other aspects of water treatment should also increase "low-carbon transformation" efforts, such as the comprehensive use of sewage treatment site space photovoltaic power generation, the use of effluent discharge drop hydroelectric power generation, the use of low energy in sewage heating and cooling, the use of fermented sludge as organic fertilizer to reduce the amount of fertilizer...

In the current upgrading of sewage treatment, adding the measurement standard of "low-carbon transformation" is the only way for the green development of sewage treatment industry.

From the system level, Ms. Jing Yuanyuan, director of the Water Industry Research Center of E20 Research Institute, believes that in the future, with the support of the dual-carbon strategy, water governance will once again strengthen the linkage model of systematic governance. She also gave the low-carbon development ideas of sewage treatment enterprises: the application of sewage source heat pump, the strengthening of intelligent management and control, the application of new technologies, the selection of low-carbon sludge paths, and the collaboration with other new energy sources such as photovoltaic.

In addition, Zhang Chen, the national master of engineering survey and design, also proposed three main strategies for the low-carbon operation of sewage plants: improving the effectiveness of sewage collection, strengthening the low-carbon operation of sewage treatment, and focusing on the utilization of sludge energy resources.

It can be seen that the "double carbon" model of sewage treatment in the future will gradually take shape in the exploration.

Data show that the current contribution of wastewater treatment industry to carbon emissions is small, and the contribution of energy consumption of urban domestic sewage treatment facilities to carbon emissions is lower. However, the "double carbon" line is the goal of the whole society, only for the specimen industry, focusing on the carbon reduction goal of the industry is the actual carbon reduction program.

In the future, China's sewage treatment and the integration of the "double carbon" goal will be more fully. On the investor exchange platform, many enterprises such as the first environmental protection, Synutron Environmental protection, Peng Harrier environmental protection and other sewage treatment enterprises, in response to investor questions, also said that they will continue to deepen the layout of green and efficient environmental protection technology, and actively fulfill the main responsibility of carbon emission reduction.
