Abstract:The urban drainage pipe network in China generally has the problems of rain erosion, overflow or overflow pollution caused by low-velocity deposition in dry season, misconnection and mixed connection of rain and sewage pipe networks, small scattered sewage discharge and interception of sewage at the end of rain and flood pipe networks. Research shows that network depositions are characterized by low organic content, high carbon content, and low nitrogen and phosphorus content. Network deposition is easy to be washed into water bodies by rainfall and deposit to the bottom of the water body again. It becomes the main reason of urban water bodies return black and stinky and hard to recover from self-purification after rainfall. According to the results of the engineering survey, this work points out that building a large-capacity, short-term and rapid purification facility with particle removal as the core function at the end of the drainage pipe network is an effective measure to effectively reduce the total amount of pollutants and phosphorus deposited into the river, which is an effective solution to the problem of rainfall pollution as well as black and odorous water bodies in China. Such management and prevention measures are also recognized by international experience.
