Description

A kind of rainwater and effluent disposing system
Technical field
The invention belongs to the technical field of pollution prevention, specifically a kind of rainwater and effluent disposing system.
Background technology
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 End treatment technology.Existing technology is such as:Cyclonic separation, sedimentation tank etc..The existing process to combined system rain sewage for a lot of patents Method is set forth and studies.As a kind of entitled " combined system pipe network overflowing rain water intercepts flow division control device " (publication number CN103643735A patent of invention), the method is unpowered, processing speed is slower;And for example entitled " combined system pipe network Vatch basin system The patent of invention of system and its control method " (publication number CN10385027A), the method is not true because of play rainfall early-stage rainwater amount Determine it is impossible to effectively cut down play tube overflow pollutional load;It is and for example entitled that " overflow rain sewage on-site elimination stepped ecological sewage control is tied The patent of invention of structure " (publication number CN101891350A), the method Ecological Disposal is slower, and is unfavorable on a large scale should in old town With.
Therefore, develop a kind of new combined system rain sewage water treatment method, realize occupation of land province, processing speed is fast, process effect The purposes such as rate height, low cost, operation maintenance convenience, the reduction to old town rain sewage pollution is significant.
Content of the invention
For the problems referred to above, the present invention provides a kind of occupation of land province, processing speed is fast, treatment effeciency is high, low cost, operation dimension Protect convenient combined system rainwater and effluent disposing system, to reduce the danger to city receiving water body for the old town combined sewer overflow rain sewage Evil.
