Urban Drainage System can be divided into combined system and separate sewage system, and in recent years, newly built city district drainage pipeline networks is most
Using confluence of rainwater and sewage drainage system.But because of reasons such as history, domestic and international old town still remains combined drainage system.Interflow
Drainage system processed not only carries conveying and the discharge of city domestic sewage, is also the passing away of rainfall runoff simultaneously, i.e. city
City's point source and the dual channel of pollution of area source.After rainfall, in the tubing giving sufficient strength of interflow, flow increases with the increase of rainfall, works as pipe
When road flow exceedes the conveying capacity of the main that dams, unnecessary part rain dirt mixing water will climb over the modes such as overflow well/Vatch basin
Draining receiving water body and pollute, this part combined sewage be referred to as combined system tube overflow (CSO).Combined system tube overflow master
Want the concentration change scope of pollutant larger, the major pollutants such as COD, the SS in some of them area are far above sanitary sewage.Existing
There is control technology, such as the transformation (separate flow system, interceptive combined system etc.) of tubing, overflow storage pond etc., and to soil
For anxiety, the old town of building dense, the method for edge treatment of tube overflow is more suitable.
The combined system tube overflow rain sewage oncoming force is fast, pollution is heavy it is therefore desirable to development process speed is fast, treatment effeciency is high
