Description
Technical field
The present invention relates to municipal drainage system field, and in particular to what a kind of control sewage and early-stage rainwater polluted divides completely
Stream system and its control method.
Background technology
Municipal drainage system is broadly divided into combined drainage system and separate sewage system.The interflow occurred earliest
Drainage system processed, it 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 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 by combined pipeline,
The rainwater that inlet for stom water along town road is collected also all enters municipal administration interflow main, and Vatch basin is set in main end.Fine day
When, all sewage are all delivered to sewage plant, and natural water is discharged into after processing.During rainfall, the rainwater at sewage and rainfall initial stage
Also sewage plant can be transported to, natural water is discharged into after processing.But with the increase of rainfall, rainfall runoff also increases,
After the flow of combined sewage exceedes the conveyance power of water for the main that dams, just have part combined sewage overflow and be directly entered nature
Water body.
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 plant.3. Vatch basin dams for the control of extensive style, it is impossible to accurately early-stage rainwater is dammed.
Separate sewage system is divided into complete separate system and incomplete separate system two again according to the difference for excluding rainwater mode
Kind drainage system.Complete separate sewage system is completely to separate rainwater and sewage, trade effluent, is carried out by different pipelines
Conveying.The sewage of resident's discharge enters trunk sewer by sewage conduct, is discharged after being then sent to sewage plant processing, inlet for stom water
The rainwater of collection enters Storm-water sewer by storm sewer, is directly discharged to natural water.Inlet for stom water along town road is received
The rainwater of collection also all enters Storm-water sewer, is directly discharged to natural water.In this separate sewage system, there is a lot
Problem：1. the part of contaminated water in residential area mistakenly enters the sewage that washing machine is discharged on storm sewer, such as balcony can be straight
Run in and be put into natural water.2. the part of contaminated water on town road mistakenly enters storm sewer, for example is produced during road cleaning
Raw sewage can be directly discharged to natural water.3. during rainfall, pollution of area source can be produced on residential area and town road, face source is dirty
Dye thing can be directly entered natural water.
Incomplete separate 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 sewage and inlet for stom water of resident's discharge are collected all is discharged by combined pipeline, is being entered
Vatch basin is set to be dammed before entering municipal drainage pipeline.The rainwater that inlet for stom water along town road is collected is done into rainwater
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, natural water is discharged into after processing, but part of contaminated water is had on town road and is directly discharged to certainly into Storm-water sewer
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, natural water is discharged into after processing, but as the increase of rainfall, rainfall runoff also increase, when combined sewage
After flow exceedes the conveyance power of water for the pipeline that dams, just have part combined sewage overflow and be directly entered Storm-water sewer, while city
The early-stage 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 can not effectively be intercepted to area source pollutants, intercepting efficiency is low.②
The sewage for entering storm sewer can not be controlled.3. during rainfall, sewage is easily carried along into natural water by rainwater.4. dam
The control of well is extensive, on the one hand more early-stage 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 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.
