Description
Technical field
The utility model belongs to technical field of drainage, and in particular to a kind of drainage system with double pump row.
Background technology
Currently, the drainage system of city and groups of building mainly includes separate system, combined system and mixed flow system, main purpose
It is collection, conveying and the processing for realizing water body.For example, the system that all waste water are treated using a kind of mode claims combined system.It is only
There are one drainage systems, claim converging system, and drainage pipeline claims combined pipeline.Waste water of different nature is treated in different ways
System claim separate system, it is general, and there are two drainage systems.One is properly termed as storm-water system, for collecting rainwater and pollution journey
Degree is very low, the industrial wastewater of water body is directly discharged without processing, and pipeline claims storm sewer.Another is properly termed as sewage
System, collects the industrial wastewater that could be discharged after sanitary sewage and needs processing, and pipeline claims sewage conduct.Mixed flow system is a kind of
System between separate system and combined system is mainly since pipeline misconnection, hybrid junction etc. cause in the region of separate system
There is waste water of different nature in section of tubing, i.e. storm sewer or sewage conduct has actually become combined pipeline.City
Waste water in sewage conduct and combined pipeline is often referred to as municipal sewage.
Densely populated with the appearance of modern house sanitary equipment and skyscraper, excrement is conveyed with current, is greatly increased
The intensity of municipal sewage；Along with industry prosperity, industrial wastewater substantial increase, the rivers and lakes of near cities occur as soon as and cannot hold
The pollution condition born.Then sewage treatment plant is added, and each water outlet is connected with pipeline, the waste water in each arterial drainage is converged
Collection sewage treatment plant is handled, and forms shutoff type converging system.The connection water outlet and waste water that shuts off is to the pipe of sewage treatment plant
Road claims shut off pipeline or wastewater interception pipe.

Well.The construction of shunting well can have a different designs, but current design and not perfect, and for different sewage quantity and rain
Water does not make improvement yet.Because there was only sewage in pipe during dry season, shunting well can stop sewage, flow to sewage pipe；Rainy season
When part rainwater and sewage are stopped and flow into sewage pipe, remaining stormwater overflow continues towards downstream by weir in well.For rain
The flow direction of water and sewage, it is most in current control method to be controlled using water level or rainfall, but existing water level control
Method or rainfall control methods, the flow-dividing control to rainwater and sewage is not fine, so as to lose meaning existing for shunting well.
At present, existing shunting well there is problems in addition to these above-mentioned defects：It is general to flow into water body therein
All it is that downstream (in such as sewage treatment plant or natural water) is emitted by gravity, but due to the applied field of shunting well
Institute is relatively broad, it is impossible to ensure that the water body in the shunting well of each can fully rely on gravity and be emitted into downstream.When this point
Stream well is arranged at low-lying place, and how carrying out the discharge prior art for the in vivo water body of well, there is no solutions.
