Technical field
The utility model is related to a kind of combined flow system pipe network systems, belong to distributing source face pollution control technology neck
A kind of domain, and in particular to combined flow system pipe network system for controlling sewage and initial rainwater pollution.
Background technology
Municipal drainage system is broadly divided into combined drainage system and separate sewage system.The interflow occurred earliest
Drainage system processed is that sewage, industrial wastewater and rainwater are blended in same pipe duct, is just directly arranged nearby without any processing
Enter water body, be stained significantly receiving water body, lot of domestic and international mature city is nearly all in this way.Now frequently with
It is interceptive combined system drainage system.
Interceptive combined system drainage system and traditional combined drainage system are essentially identical in structure, and distinctive points are
Interceptive combined system drainage system is provided with Vatch basin between municipal administration interflow main pipe and sewage treatment plant.Interceptive combined system is arranged
When water system works, the rainwater that the sewage and inlet for stom water of resident's discharge are collected all enters municipal administration interflow main pipe by combined pipeline,
All into municipal administration interflow main pipe, Vatch basin also is set in main pipe end for the rainwater that inlet for stom water along town road is collected.Fine day

Before entering municipal drainage pipeline Vatch basin is set to shut off.The rainwater that inlet for stom water along town road is collected, which enters rainwater, to be done
Pipe, is directly discharged to natural water.During fine day, the sewage of residential area discharge is trapped to trunk sewer, is then sent to sewage
Factory is discharged into natural water after processing, but part of contaminated water is had on town road and enters Storm-water sewer and is directly discharged to certainly
Right water body.During rainfall, the sewage and the rainwater at rainfall initial stage of residential area discharge can be also trapped to trunk sewer, be then sent to
Sewage plant is discharged into natural water after processing, but with the increase of rainfall, rainfall runoff also increases, when combined sewage
After conveyance power of water of the flow more than the pipeline that shuts off, just have part combined sewage overflow and be directly entered Storm-water sewer, while city
The initial rainwater of a large amount of pollutants is carried on political affairs road can also be directly entered Storm-water sewer, be then discharged to natural water.This
The problem of kind of drainage system is mainly：1. whole system cannot effectively intercept area source pollutants, intercepting efficiency is low.②
Sewage into storm sewer cannot be controlled.3. during rainfall, sewage is easily carried along into natural water by rainwater.4. shut off
The control of well is extensive, on the one hand more initial rainwaters may not be sent into sewage plant processing so that area source pollutants discharge
Natural water has been arrived, on the other hand substantial amounts of later stage rainwater sewage plant may be sent into, add the load of sewage plant, reduce
The treatment effeciency of sewage plant.
All things considered, there is problems with for current run-off system：First, it is impossible to which pollution of area source is controlled；The
Two, control is extensive, it is impossible to which sewage and initial rainwater are accurately controlled；3rd, pipeline hybrid junction, sewage has been directly discharged to certainly
Right water body；4th, for the area of land used anxiety, end treatment cannot effectively be implemented.
