Description

A kind of combined drainage system and control method of sewage and rainwater
Technical field
The present invention relates to a kind of drainage system pipe network system, and in particular to a kind of drainage system system of sewage and rainwater System and 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 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 collaborating house steward, 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. what is dammed 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 sanitary sewage, trade effluent, by different pipelines Conveyed.The sewage of resident's discharge enters trunk sewer by sewage conduct, is discharged 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 Natural water can be directly discharged to.2. the part of contaminated water on town road mistakenly enters storm sewer, such as road cleaning Caused sewage can be directly discharged to natural water.3. during rainfall, pollution of area source, face can be produced on residential area and town road Source pollutants 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 collaborating house steward, 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.
Meanwhile the present inventors have additionally discovered that, for old town either villages within the city etc. of some mature cities, such case is more Seriously, not perfect enough due to first rain dirt design of pipe networks, many old towns or villages within the city etc. do not have in unit area Storm-water sewer and sewage treatment plant, or the rainwater that original interflow house steward does not collect to it is with being discharged into sanitary sewage therein Separated, sewage and rainwater is directly discharged to municipal wastewater main, the rainwater for being discharged into trunk sewer adds sewage and done The processing intensity of pipe end sewage treatment plant, make its efficiency low.
If in addition, if old town or region early-stage rainwater feature unobvious residing for villages within the city, by middle and later periods rainwater Shunting, which is discharged into natural water, still can produce pollution.
