Description

A kind of region burst rainwater based on separate system pipe network divides stream processing system
Technical field
The present invention relates to urban rainwater and process system regions, divide stream processing system in particular to a kind of region burst rainwater based on separate system pipe network.
Background technology
Current social, Development of Urbanization is increasingly rapider, and the area in city is increasing, and urban rainwater web frame becomes increasingly complex, and the processing pressure that urban rainwater processes system is increasing.At present, Urban Rainwater Pipe Networks is divided into three kinds: separate system, combined system and mixed flow system.
The separate system water treatment system of early stage has complete Storm Sewer Network structure, urban sewage system and Storm Sewer Network are kept completely separate, municipal sewage enters into either directly through sewage network and is collected in sewage disposal system and processes, Storm Sewer Network directly collects city rainwater drainage in natural water, and both do not connect and do not interfere with each other.The separate system Storm Sewer Network of early stage does not account for the problem that early-stage rainwater exists severe contamination, along with industrialized continuous progress, the pollution level of early-stage rainwater is increasingly severe, if early-stage rainwater not being carried out process and being directly discharged in natural water, natural water will be caused serious pollution.
Therefore, separate system Storm Sewer Network of the prior art is typically in certain region, city and builds a storage pond or Vatch basin structure, carries out process avoid being directly discharged in natural water by getting up to be transported to urban sewage treatment system by early-stage rainwater accumulation.Use the Storm Sewer Network structure of this separate system, can effectively early-stage rainwater be transported in urban sewage treatment system, early-stage rainwater is avoided to pollute Urban Natural water body, later stage clean rainwater is directly discharged to natural water and alleviates again the pressure of urban sewage treatment system, on whole rain water distribution, the Storm Sewer Network of this separate system has a lot of advantages, is more suitable for the use in existing city.
But it is as the continuous extension of city scope, there is very big defect in existing separate system Storm Sewer Network structure, existing city is typically in the structure of whole city and arranges the water treatment system that a few set is large-scale, the region area that often set water treatment system contains is too big, do not fully take into account rainwater time delay on pipeline or rainwash, first rain or be directly discharged to natural water to cause serious contamination accident, it is mix with substantial amounts of later stage clean rainwater to be flowed in sewage treatment plant and seriously increase the processing pressure of sewage treatment plant, for the regulation and control of early-stage rainwater and later stage rainwater unreasonable, can not be totally separated from.Such as, storage pond has been built in the area near urban sewage treatment system in certain city, assuming that M area urban rainwater in this storage pond 1Km, M area is directly discharged to storage pond by pipe network, it is T1 that the city initial rainwater in M area is fully discharged into time of storage pond.For the area farther out of the distance storage pond beyond this region, it is assumed that it is T2 that the city initial rainwater that air line distance is 10km, N area of N area distance storage pond is fully discharged into the time of storage pond, and from time length, T2 to be obviously far longer than T1.And after storage pond is collected and expired early-stage rainwater, the rainwater exceeded begins to be automatically discharged in natural water, storage pond is T3 from starting to collect rainwater to the time started to natural water discharge.During actual motion, iff the rainwater emission behaviour taking M area into account, namely regional for M early-stage rainwater can enter into the clean rainwater of sewage disposal system intermediary and later stages by storage pond and can be discharged in natural water, need T3 more than T1, once beyond T3, storage pond immediately discharges to natural water, and now N area flows to the rainwater of storage pond and still pollutes very serious early-stage rainwater, namely T3 is less than T2, can cause very serious pollution undoubtedly to natural water discharge.
Iff the rainwater emission behaviour considering N area, namely T3 is more than T2, and the early-stage rainwater in that N area can enter in urban sewage treatment system by storage pond, is well processed.But for M area, M area has substantial amounts of later stage clean rainwater to be also discharged in urban sewage treatment system within the time of the early-stage rainwater in storage pond discharge N area, and such emission behaviour can cause very big processing pressure to urban sewage system.It addition, M area is generally, with the pipe network in N area, the situation of connection during actual motion, due to the difference of distance, the delay effect on road, the later stage clean rainwater that the early-stage rainwater in N area may be regional for severe contamination M, also result in the unreasonable of rainwater emission behaviour.
