This project belongs to urban water supply and drainage engineering (subject code: 5605510).
In recent years, frequent sudden water pollution incidents in urban water sources have seriously threatened the safety of water supply quality. At present, there is still insufficient research on the rapid identification of sudden water pollution in open drinking water sources and surrounding water bodies, assessment of emergency response capabilities of water supply systems and disposal technical systems. Various disposal technologies are still in a single link, and there is an urgent need for full-process collaborative disposal. Systematic research and promotion and application of disposal technology and emergency decision-making.
Shanghai is located at the lowest reaches of the Yangtze River and Taihu Lake basins, and its water source areas are vulnerable to risk sources of movement of surrounding water bodies and upstream water quality risks. In view of this, the project unit carried out research and application practice in this field, forming research results from risk identification to full-process emergency response technical systems, and successfully applied them to the production practice of drinking water sources in the Yangtze River and Huangpu River. Key technological innovation points include: (1) Risk identification and assessment-monitoring and early warning technology for sudden water pollution in open drinking water sources. In view of the complexity and diversity of mobile risk sources, the short distance of "source-sink", the uncertainty of occurrence time, place and form, and the cross-department coordination of Incident Response Service, we have studied and established a risk sharing mechanism for mobile risk source monitoring systems and cross-department interconnection, three-level linkage monitoring and early warning technology, and rapid identification and judgment of pollution types, achieving rapid identification, assessment and judgment of water quality risks and pollution. (2) Full-process emergency response technology-water supply system emergency capability assessment and response technology system. On the basis of the research on the evaluation methods of emergency response capabilities and emergency expansion capabilities of the water supply process, the emergency reduction technical methods for the entire process of "water intake--water pipes and canals---water plants" were systematically studied, forming the emergency response capabilities of the water supply system. Assessment and disposal technical system. (3) Operational emergency decision-making platform--an information platform for emergency assessment and decision-making command coordinated between government and enterprises. Based on the tidal dynamic model of the water intake and surrounding water bodies and the hydrodynamic model of raw water pipes and canals, the urban multi-water source hierarchical emergency dispatch technology has been researched and formed, and an emergency decision-making and command platform coordinated by government and enterprises has been built to realize risk identification, emergency response, information release, etc. Operational functions.
The technical achievements of this project have been adopted and applied by Shanghai City Water Affairs and Environmental Protection Department, Shanghai City Investment Raw Water Company, Shanghai City Investment Water Group and other government departments and water supply enterprises. They have been successfully applied to the Huangpu River water source water supply system and have been promoted to the Yangtze River Estuary Qingcaosha, Chenhang, and Dongfeng Xisha water source water supply systems, providing experience for emergency disposal of water pollution in Jiangsu and Zhejiang regions and the whole country. Water quality monitoring and early warning technology for sudden pollution in water sources was included in the 2010 World Expo security project, ensuring the safety of water supply at the World Expo; As a business management platform that combines peacetime and wartime operations, the emergency decision-making platform was adopted by Shanghai City Water Affairs Bureau, Urban Investment Water Group and other units. It successfully responded to more than 10 sudden pollution accidents such as oil pollution and chemical pollution between 2010 and 2014. It played a particularly prominent role in the emergency response to the 2013 "dead pig" incident in the Huangpu River, ensuring the safety of residents 'drinking water. Relying on the results of this project, Shanghai City has released more than 10 water supply safety guarantee technical plans, including the "Shanghai City Water Supply Industry Expo Guarantee Plan", the "Shanghai City Water Supply Dispatch Emergency Response Plan", and the "Huangpu River Raw Water Pollution Accident Emergency Response Technical Plan." The project has applied for a total of 14 national patents, including 4 invention patent authorizations, 3 utility model patents authorizations, 3 software copyrights, published 28 papers, including 3 SCI/EI articles, trained 3 postdoctoral students, 5 doctoral students, and 11 master's students; trained 4 professor-level senior engineers, 7 senior engineers, and 6 engineers. The research and development results of this project have promoted the progress of key technologies for sudden pollution control of drinking water sources in my country, and have good market promotion prospects.
