【Abstract】 With the development of the urbanization process,the main function of urban rivers and lakes in Beijing from the water supply,flood control,and drainage gradually developed into flood control,drainage,water landscape,water supply from surface water,storm water into surface water of Guanting and Miyun Reservoir,recycled water,storm water.This paper analyzes the major rivers and lakes in Beijing supply water content ratio and the main pollutants,identifies the key pollution sources of water supply,establishes an integrated technology with source pollutants reduction and control,integrated reduction and control of municipal stormwater pipeline,and biotechnology controlled by pollution measures,it has laid a good foundation for the realization of Beijing’s overall goal of livable city.更多还原
