Description

Technical Field

[0001] The utility model relates to the technical field of municipal rainwater and sewage diversion, in particular to a municipal rainwater and sewage diversion system. Background Art

[0002] In the process of municipal construction, the construction of drainage facilities is very important. Through municipal drainage facilities, rainwater and sewage can be separated, so that rainwater and sewage can go their own way, reducing the pressure on sewage treatment plants, realizing effective sewage recycling, effectively reducing the discharge of pollutants, and protecting the urban water environment. In the prior art, the rainwater and sewage diversion system is mainly realized by setting up two sets of pipe networks to collect and discharge rainwater and sewage separately. Rainwater is directly discharged into natural water bodies or water outlets through the rainwater pipe network, while sewage enters the sewage treatment plant for treatment through the sewage pipe network. It has a simple structure and stable operation. However, during use, when the rainfall increases, the discharge of rainwater needs to increase. Due to the limitation of the diameter of the rainwater pipe, the discharge speed of rainwater is certain, resulting in a large drainage pressure of the rainwater pipe network, which affects the normal operation of the rainwater and sewage diversion system.
