China News Agency, Beijing, August 17 (Reporter Zhou Rui) China's National Development and Reform Commission spokesperson Meng Wei said in Beijing on the 17th that in recent years, China has effectively improved the efficiency of urban sewage collection and treatment, but the sewage treatment capacity of various regions is not balanced. , The construction and operation of the sewage pipe network is relatively weak, the sewage collection efficiency is low, and the sludge resource utilization and disposal are still not standardized and other problems are still prominent.
She said that in the future, China will start to make up for its shortcomings and weaknesses from four aspects, with the focus being to stick to problem orientation and target key links.
One is to make up for shortcomings in sewage treatment capacity, strengthen capacity building, and solve the problems of uneven distribution and capacity mismatch. On the basis of overall consideration of urban layout and processing needs, speed up the construction of processing facilities.
Focus on the Beijing-Tianjin-Hebei, Yangtze River Economic Belt and other key regional cities, and put forward higher requirements for full coverage of centralized processing facilities. In water-deficient areas and sensitive areas of the water environment, promote the use of sewage resources for ecological replenishment, industrial water and municipal water, as a beneficial supplement to conventional water resources.
The second is to complement the shortcomings of the collection pipe network, improve collection efficiency, and solve the problems of blank areas in the pipe network and the renewal of the old pipe network. Emphasize the "integration of factories and networks", combined with the transformation of old communities, and speed up the filling of the "capillaries" for sewage collection. Vigorously promote the cleanup and diversion of sewage, the renewal and repair of pipe networks, and the transformation of mixed connections to reduce sewage leakage during transportation and improve the efficiency of centralized collection.
Encourage areas with relatively large rainfall in the south to adopt various methods such as overflow outlet renovation and interception well renovation to promote the renovation of rain and sewage combined pipe network, reduce the frequency of overflow pollution under extreme weather such as rain and flood, and alleviate urban waterlogging.
The third is to make up for the shortcomings of resource treatment, promote the harmless resource treatment and disposal of sludge, solve the problem of the outlet of sludge in the actual treatment process, choose the disposal technology route according to local conditions, limit the landfill of sludge and gradually reduce the scale, Large and medium-sized cities with tight land use took the lead in promoting sludge incineration.
The fourth is to make up for the shortcomings of the basic data platform, promote the construction of information systems, and solve the problems of unclear pipe network base and unclear operating status. All localities should conduct thorough investigations of the domestic sewage collection pipeline network, establish a geographic information system in an orderly manner, and explore the construction of an intelligent management platform.
