Description
Technical field
The present invention relates to a kind of face pollution control system and its control method, belongs to distributing source face pollution control technology
A kind of field, and in particular to face pollution control system and its control method for drainage system pipe network system.
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 sanitary sewage, industrial wastewater and rainwater are blended in same pipe duct, without any processing with regard to directly
Water body closely is discharged into, is stained significantly receiving water body, lot of domestic and international mature city is nearly all in this way.Often adopt now
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 and sewage treatment plant.Interceptive combined system is arranged
When water system works, the rainwater that the sanitary sewage and inlet for stom water of resident's discharge are collected is all dry into municipal administration interflow by combined pipeline
Manage, the rainwater that the inlet for stom water along town road is collected also all enters municipal administration interflow main.During fine day, all sewage are all delivered to
Sewage treatment plant, natural water is discharged into after processing.During rainfall, the rainwater at sewage and rainfall initial stage can also be transported to sewage
Treatment plant, natural water is discharged into after processing.But with the increase of rainfall, rainfall runoff also increases, when combined sewage
After flow exceedes the conveyance power of water for the main that dams, just have part combined sewage overflow and be directly entered natural water.
For this combined drainage system, its problem is mainly：1. during rainfall, it can be produced on residential area and town road
Pollution of area source, although existing combined drainage system is dammed in end provided with Vatch basin, the interception ratio of design
Not enough so that Vatch basin could not intercept to area source pollutants, and area source pollutants are directly entered natural water, to natural water
Pollute.2. to be controlled to pollution of area source, it is necessary to increase the size of Vatch basin, increase the size for the main that dams,
Increase the capacity of sewage treatment plant.3. Vatch basin dams for the control of extensive style, it is impossible to accurately early-stage rainwater is cut
Stream.
Combined drainage system is divided into complete combined system and incomplete combined system two again according to the difference for excluding rainwater mode
Kind drainage system.Complete combined drainage system is to be kept completely separate rainwater and sanitary sewage, trade effluent, by different pipelines
Conveyed.The sanitary sewage of resident's discharge enters trunk sewer by sewage conduct, is then sent to sewage treatment plant's processing
After discharge, inlet for stom water collect rainwater Storm-water sewer is entered by storm sewer, be directly discharged to natural water.Town road edge
The rainwater that the inlet for stom water of line is collected also all enters Storm-water sewer, is directly discharged to natural water.In this combined drainage system
In, it there are problems that a lot：Done washing 1. the part sanitary sewage in residential area mistakenly enters on storm sewer, such as balcony
The sanitary sewage of machine discharge can be directly discharged to natural water.2. the part of contaminated water on town road mistakenly enters rain pipe
Road, such as sewage caused by road cleaning can be directly discharged to natural water.3. during rainfall, meeting on residential area and town road
Pollution of area source is produced, area source pollutants can be directly entered natural water.
Incomplete combined system is primarily directed on the rainwater and town road that in the collection processing of rainwater, residential block is collected
The rainwater being collected into is separated.The rainwater that the sanitary sewage and inlet for stom water of resident's discharge are collected all is discharged by combined pipeline,
Vatch basin is set to be dammed before municipal drainage pipeline is entered.The rainwater that inlet for stom water along town road is collected enters rain
Water conduit tube, it 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 treatment plant, natural water is discharged into after processing, but had on town road part of contaminated water into Storm-water sewer and it is direct
It is discharged into natural water.During rainfall, the sewage and the rainwater at rainfall initial stage of residential area discharge can be also trapped to trunk sewer, so
After be delivered to sewage treatment plant, natural water is discharged into after processing, but as the increase of rainfall, rainfall runoff also increase,
After the flow of combined sewage exceedes the conveyance power of water for the pipeline that dams, just have part combined sewage overflow and be directly entered rainwater
Main, while the early-stage rainwater that a large amount of pollutants are carried on town road can also be directly entered Storm-water sewer, be then discharged to
Natural water.The problem of this drainage system is mainly：1. whole system can not effectively be intercepted to area source pollutants, and
Intercepting efficiency is low.2. the sewage for entering storm sewer can not be controlled.3. during rainfall, sanitary sewage is easily entrained into by rainwater
Enter natural water.4. the control of Vatch basin is extensive, on the one hand more early-stage rainwaters may not be sent into sewage disposal factory and office
Reason so that area source pollutants have been discharged into natural water, on the other hand substantial amounts of later stage rainwater may be sent into sewage treatment plant,
The load of sewage treatment plant is added, reduces the treatment effeciency of sewage treatment 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 early-stage rainwater are accurately controlled；3rd, pipeline hybrid junction, sewage has been directly discharged to certainly
Right water body；4th, for the area that land used is nervous, end treatment can not effectively be implemented.
