Description
Technical field
The present invention relates to urban rainwater processing system fields, in particular to a kind of region fragment rain based on separate system pipe network
Moisture stream processing system.
Background technology
Current social, Development of Urbanization is more and more rapider, and the area in city is increasing, and urban rainwater web frame is more next
More complicated, the processing pressure of urban rainwater processing system is increasing.Currently, Urban Rainwater Pipe Networks are divided into three kinds：Separate system, conjunction
Stream system and mixed flow system.
The separate system water treatment system of early stage possesses complete Storm Sewer Network structure, and urban sewage system is complete with Storm Sewer Network
Fully separating, municipal sewage is directly entered in sewage disposal system by sewage network and is collected and handles, and Storm Sewer Network is straight
It receives in collection city rainwater drainage to natural water, the two is not connected to and does not interfere with each other.The separate system Storm Sewer Network of early stage is not examined
Consider initial rainwater to there are problems that seriously polluting, with industrialized continuous progress, the pollution level of initial rainwater is increasingly
Seriously, it is directly discharged in natural water if not carrying out processing to initial rainwater, serious dirt will be caused to natural water
Dye.
Therefore, separate system Storm Sewer Network in the prior art is generally built a storage pond in some region of city or is cut
Flow well construction, by by initial rainwater accumulation get up to be transported to urban sewage treatment system carry out processing avoid being directly discharged to from
In right water body.Using the Storm Sewer Network structure of this separate system, can initial rainwater be effectively transported to municipal sewage treatment
In system, initial rainwater is avoided to pollute Urban Natural water body, later stage clean rainwater is directly discharged to natural water and alleviates city again
The pressure of city's sewage disposal system, on entire rain water distribution, the Storm Sewer Network of this separate system has the advantages that very much, is more suitable for
The use in existing city.
But with the continuous extension of city scope, there are prodigious defects for existing separate system Storm Sewer Network structure, existing
There is city that the large-scale water treatment system of several sets is generally set in entire city structure, often covers the area surface that water treatment system covers
Product is too big, does not fully take into account delay time of the rainwater on pipeline or rainwash, otherwise first rain is to be directly discharged to
Natural water causes serious contamination accident or is to mix to be flowed in sewage treatment plant sternly with a large amount of later stage clean rainwater
Increase the processing pressure of sewage treatment plant again, regulation and control for initial rainwater and later stage rainwater are simultaneously unreasonable, cannot carry out completely
Separation.For example, storage pond has been built in certain city in the area close to urban sewage treatment system, it is assumed that the areas M are apart from the tune
Urban rainwater in the areas reservoir 1Km, M is directly discharged to storage pond by pipe network, and the city initial rainwater in the areas M is discharged completely
Time to storage pond is T1.For the area apart from storage pond farther out beyond the region, it is assumed that the areas N are apart from storage pond
Air line distance is 10km, and it is T2 that the city initial rainwater in the areas N, which is fully discharged into the time of storage pond, from the point of view of time length,
T2 obviously will be far longer than T1.And after initial rainwater has been expired in storage pond collection, the rainwater exceeded begins to be automatically discharged into certainly
In right water body, since storage pond be T3 start the time that collection rainwater is discharged to natural water.When actual motion, if only
Only take the rainwater emission behaviour in the areas M into account, i.e. the initial rainwater in the areas M can enter sewage disposal system by storage pond
The clean rainwater of intermediary and later stages can be discharged into natural water, and T3 is needed to be more than T1, once exceeding T3, storage pond is immediately to certainly
Right discharge into water, and the areas N flow to the rainwater of storage pond and still pollute very serious initial rainwater at this time, i.e. T3 is less than T2, to
Natural water discharge can undoubtedly cause very serious pollution.
If only in view of the rainwater emission behaviour in the areas N, i.e. T3 is more than T2, and the initial rainwater in the areas that N can lead to
It crosses storage pond to enter in urban sewage treatment system, be handled well.But for the areas M, the areas M have largely
Later stage clean rainwater be also discharged into urban sewage treatment system within the time of the initial rainwater in storage pond discharge N areas
In, such emission behaviour can cause prodigious processing pressure to urban sewage system.In addition, the areas M and N when actual motion
The pipe network in area is generally connection situation, and due to the difference of distance, the delay on road acts on, and the initial rainwater in the areas N may
The later stage clean rainwater in the serious areas pollution M, also results in the unreasonable of rainwater emission behaviour.
