Description
Technical field
The utility model relates to a kind of drainage system pipe network systems, and in particular to a kind of combined system row of sewage and rainwater
Water system.
Background technique
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 the 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 row
When water system works, the rainwater that the sewage and inlet for stom water of resident's discharge are collected all passes through interflow general pipeline and enters municipal administration interflow main pipe,
The rainwater that inlet for stom water along town road is collected also all enters municipal administration interflow main pipe, and Vatch basin is arranged in main pipe end.Fine day
When, all sewage are all delivered to sewage plant, are discharged into natural water after processing.When rainfall, the rainwater of sewage and rainfall initial stage
Also it can be transported to sewage plant, be discharged into natural water after processing.But with the increase of rainfall, rainfall runoff also increases,
When combined sewage flow be more than shut off main pipe conveyance power of water after, just have part combined sewage overflow and be directly entered nature
Water body.
For this combined drainage system, problem is mainly: 1. when rainfall, can generate on residential area and town road
Pollution of area source shuts off although existing combined drainage system is equipped with Vatch basin in end, the interception ratio of design
Not enough, so that Vatch basin could not intercept area source pollutants, area source pollutants are directly entered natural water, to natural water
It pollutes.2. to control pollution of area source, it is necessary to increase the size of Vatch basin, increases the size for the main pipe that shuts off,
Increase the capacity of sewage plant.3. shutting off of shutting off is the control of extensive style, cannot accurately shut off to initial rainwater.
Separate sewage system and is divided into complete separate system and incomplete separate system two according to the difference for excluding rainwater mode
Kind drainage system.Complete separate sewage system is completely to separate rainwater and sanitary sewage, trade effluent, by different pipelines
It is conveyed.The sewage of resident's discharge enters trunk sewer by sewage conduct, discharges after being then sent to sewage plant processing, rain
The rainwater that the mouth of a river is collected enters Storm-water sewer by storm sewer, is directly discharged to natural water.Rainwater along town road
The rainwater that mouth is collected also all enters Storm-water sewer, is directly discharged to natural water.In this separate sewage system, there is
Many problems: 1. the part of contaminated water in residential area mistakenly enters the sewage that washing machine is discharged on storm sewer, such as balcony
It can be directly discharged to natural water.2. the part of contaminated water on town road mistakenly enters storm sewer, such as road cleaning
When the sewage that generates can be directly discharged to natural water.3. when rainfall, pollution of area source, face can be generated on residential area and town road
Source pollutants can be directly entered natural water.

The rainwater being collected into is separated.Resident discharge sewage and inlet for stom water collect rainwater all pass through interflow general pipeline discharge, into
Vatch basin is arranged before entering municipal drainage pipeline to shut off.It is dry that the rainwater that inlet for stom water along town road is collected enters rainwater
Pipe, is directly discharged to natural water.When 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 has part of contaminated water on town road and enter Storm-water sewer and be directly discharged to certainly
Right water body.When 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 has part combined sewage overflow and be directly entered Storm-water sewer, while city
The initial rainwater that a large amount of pollutants are carried on political affairs road can also be directly entered Storm-water sewer, be then discharged to natural water.This
The problem of kind drainage system is mainly: 1. whole system cannot effectively intercept area source pollutants, and intercepting efficiency is low.②
The sewage for entering storm sewer cannot be controlled.3. when rainfall, sewage is easily carried along into natural water by rainwater.4. shutting off
The control of well is extensive, on the one hand more initial rainwaters may not be able to be sent into sewage plant processing, so that area source pollutants discharge
Natural water has been arrived, on the other hand a large amount of later period rainwater sewage plant may be sent into, increase the load of sewage plant, reduce
The treatment effeciency of sewage plant.
All things considered, there is following problems for current run-off system: first, pollution of area source cannot be controlled；The
Two, control is extensive, cannot accurately be controlled sewage and initial rainwater；Third, pipeline hybrid junction, sewage have been directly discharged to certainly
Right water body；4th, for the area of land used anxiety, end treatment cannot effectively be implemented.
Meanwhile the utility model people also found, for the old town either villages within the city etc. of some mature cities, such case
It is even more serious, it is incomplete due to first rain dirt design of pipe networks, in the unit areas such as many old towns or villages within the city
The rainwater that does not have Storm-water sewer and sewage treatment plant or original interflow general pipeline not to collect to it and it is discharged into life therein
Sewage is separated, and sewage and rainwater is made to be directly discharged to municipal wastewater main pipe, and the rainwater for being discharged into trunk sewer increases dirt
The processing intensity of water conduit tube end sewage treatment plant, makes its inefficiency.
