Abstract:Affected by the rainfall and drainage, the water quality of some rivers is unstable after rain, and the discharge-into-river pollution of flood control pumping stations has become the main factor affecting the stability and continuous improvement of river water quality in Shanghai. Combined with the current situation, reasons, existing control measures, effectiveness, and existing problems of the pumping stations to discharge into rivers in Shanghai, the ideas of discharge-into-river control is further analyzed, which provides a reference for the subsequent discharge-into-river control and river water environment improvement.
