There are still bottlenecks in technology, facilities, funds, etc., how to break the situation of rural domestic sewage treatment?

Release time:


Rural domestic sewage refers to the sewage generated in the daily life of rural areas, as well as the sewage generated by business activities such as rural public welfare undertakings, public services and homestays, catering, washing, beauty salons, etc.

Since the 18th National Congress of the Communist Party of China, under the promotion of the implementation of the rural revitalization strategy, the improvement of the rural living environment, and the "13th Five-Year Plan" for the comprehensive improvement of the national rural environment, my country's rural domestic sewage treatment has achieved leapfrog development.

In Guangyuan City, there are 1046 villages like Sanwill Village that use sewage treatment facilities. By the end of October 2023, 68.32 percent of domestic sewage in administrative villages in Sichuan Province had been effectively treated, up about 50 percentage points from the beginning of 2019.

"It can be said that the past decade has been the fastest improvement in rural domestic sewage treatment capacity, and the investment in treatment facilities has been increasing." Peng Yingdeng, a researcher at the National Urban Environmental Pollution Control Technology Research Center, said frankly that despite this, there are still a large number of facilities "basking in the sun" in rural domestic sewage treatment.

Even in Beijing, the construction of environmental infrastructure in rural areas is still lagging behind, and it has increasingly become a shortcoming of urban construction. The second round of central ecological and environmental protection inspectors found that the implementation plan of Beijing's rural revitalization strategy clearly stated that by the end of 2020, the city's rural sewage treatment should cover 1847 villages, but as of September 2020, there are still 282 villages that have not completed their tasks; rural areas The problem of sewage treatment facilities focusing on construction and neglecting management is relatively common, and about 15% of the completed facilities cannot operate normally.

"In the rural areas of the underdeveloped areas in the central and western regions of my country, it is more common that domestic sewage treatment facilities cannot be built or used." Peng Yingdeng said that at present, my country's rural domestic sewage treatment is still in the early stage, and the technology is not yet mature. Some places copy urban sewage treatment technology, and some places are too pursuing low-cost treatment, and there are even phenomena such as mixed technology. The blind choice of management technology model is one of the important reasons for the late facilities to "bask in the sun.

At present, the urban domestic sewage treatment method is to collect the sewage through the pipe network and transport it to the sewage treatment plant for unified treatment. This kind of "big concentration, big processing" technology is relatively mature and standardized. However, the rural areas are sparsely populated, the construction cost of sewage collection pipe network is high, and the utilization rate is low. In addition, the situation varies from place to place, and the domestic sewage treatment presents the characteristics of "large dispersion and small concentration.
