Description

A kind of drainage system with rain processing system

Technical field

The utility model belongs to technical field of drainage, and in particular to a kind of drainage system with rain processing system.

Background technology

Currently, the drainage system of city and groups of building includes mainly 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 for treating all waste water using a kind of mode claims combined system.It is only There are one drainage systems, and converging system, drainage pipeline is claimed to claim 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 Industrial wastewater very low, without processing direct emission water body is spent, 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 flow, is greatly increased The intensity of municipal sewage；Along with industry prosperity, industrial wastewater increases significantly, and the rivers and lakes of near cities occur as soon as and cannot hold The pollution condition born.Then sewage treatment plant is added, pipeline is used in combination to connect each water outlet, the waste water in each arterial drainage is converged Collection sewage treatment plant is handled, and shutoff type converging system is formed.Connection water outlet and shut off waste water to sewage treatment plant pipe Road claims shut off pipeline or wastewater interception pipe.

Wastewater flow rate abruptly increase when rainfall shuts off pipeline and sewage treatment plant is necessarily required to if all waste water are all retained It is very extensive, excessively increase engineering cost.So the inspection shaft of arterial drainage and intercepting sewer intersection is generally replaced with shunting Well.The construction of shunting well can have a different designs, but current design and not perfect, and be directed to different sewage quantity and rain Water does not make improvement yet.Because only having sewage, shunting well that can stop sewage in pipe when dry season, sewage pipe is flowed to；Rainy season When part rainwater and sewage stopped and flowed 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, to lose meaning existing for shunting well.

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides a kind of draining system with rain processing system System, the drainage system shuts off and shunts for rainwater and/or sewage, by reasonably regulating and controlling so that water body reasonable diffluence, Realize the reasonable disposition of resource.

The utility model proposes following technical solutions：
