[0002] With the rapid development of urbanization, the demand and utilization of water resources are increasing, and the resulting water pollution problem is becoming increasingly serious. Urban water environment protection has become an important task in urban ecological construction. Pollutants enter urban rivers through the urban drainage system with rainwater runoff, which is an important cause of urban water pollution. The rainwater itself is not seriously polluted, but during the rainfall and drainage process, rainwater carries suspended particles on the road surface into the rainwater pipes, sediments in the rainwater pipes, and the widespread mixing of rainwater and sewage in the pipe network system. Rainwater is polluted. Direct discharge will have an adverse effect on the river ecology. Therefore, it is necessary to filter and preliminarily purify the rainwater before discharging it into the river.
