It breaks through the overall design of urban water pollution control systems, operation control of the entire process, and ecological restoration of water bodies. , And carried out technology integration application demonstration, and established a technical system for urban water pollution control and water environment improvement. The first is the development of a set of high-standard phosphorus and nitrogen removal and stabilization operation technologies for urban sewage with new technological processes such as enhanced MBR, improved A2O, and enhanced nitrification of suspended fillers, supporting more than 1,000 urban sewage treatment plants. The effluent is stable, meets the requirements of level A and higher discharge standards, significantly reduces the pollution discharge load of the river basin, and realizes the large-scale ecological utilization of recycled water. The second is the development of a full-chain sludge treatment and disposal technology that solves the key technical difficulties of reducing, stabilizing, harmless, and reusing sludge in urban sewage treatment plants. It has constructed 32 demonstration and promotion projects for China's sewage The safe disposal and resource utilization of plant sludge provide technical support. The third is to build an urban rainwater management and control technology system with perfect drainage pipe network, waterlogging prevention, runoff pollution control, and utilization of rainwater resources as the core, which comprehensively supported the national black and odorous water body management and sponge city construction work.
In the field of drinking water safety and security, we have broken through a number of key technologies for water quality purification, established a drinking water safety and security technology system from "source to faucet" throughout the process, and improved China's ability to ensure water safety.
The water project is aimed at problems such as pollution of drinking water sources in China, frequent occurrence of water pollution incidents, and hidden dangers of water supply systems. It has systematically developed key technologies such as water source protection, water quality purification, pipe network transmission and distribution, water quality monitoring, early warning and emergency management, and effective management. It has solved the technical problems of removing toxic and harmful substances such as algae, odor, ammonia nitrogen, arsenic, etc., and carried out technology demonstration and large-scale application in key areas and typical towns such as the Taihu Lake Basin, the South-to-North Water Diversion Area, the lower reaches of the Pearl River, and directly benefited more than 100 million people. Through special water technical support, the water receiving areas of the South-to-North Water Transfer Project in Beijing and other cities responded to the "yellow water" problem of the pipe network caused by water source switching in a timely manner. Water supply safety; Jiangsu Province achieved full coverage of urban drinking water in-depth treatment, which effectively avoided the water supply crisis in Wuxi and other cities caused by the outbreak of cyanobacteria in Taihu Lake; Jiaxing effectively solved the seasonal high ammonia nitrogen removal problem of heavily polluted river network water sources; Shenzhen in Yantian District launched a direct drinking water demonstration. The water special organization researched and prepared the "Guidelines for the Reform of Urban Water Supply Facilities", which supported the preparation and implementation of the national water supply plan during the "Twelfth Five-Year Plan" and "Thirteenth Five-Year Plan" and the national city and county drinking water quality inspection (sampling inspection) and standardized water supply management The work has promoted the overall improvement of China's drinking water safety and technical support capabilities, and made an important contribution to "let the people drink safe water."
China Construction News: What are the core equipment products that have been broken through the implementation of the water project? What steps have been taken?
