Abstract
The invention discloses a kind of method for controlling the sewage that each section is cut in dirty pipe in drainage system to import trunk sewer and facility of regulating and storing during rainfall, the method of the invention in the case where utilizing existing resource to greatest extent, pass through reasonable disposition, by water quality in each burst region it is poor, it is with serious pollution just rain be emitted into by first section of dirty pipe of each section in trunk sewer, sewage treatment plant is entered back into be handled, it is emitted into by second section of dirty pipe of each section in facility of regulating and storing, enters back into sewage treatment plant and handled.Sewage can so be reduced as far as possible to the pollution level in burst region, while cleaner rainwater is not discharged into sewage treatment plant, the load of sewage treatment plant is reduced, so that existing resource realizes optimization collocation.Water body in the region of different pollution levels is targetedly fast and effectively carried out emission treatment by the method for the present invention, so as to realize the reasonable discharge of water body.
Description
Technical field
The invention belongs to drainage system control technique field, and in particular to each is controlled in drainage system during a kind of rainfall
The method that the sewage that area is cut in dirty pipe imports trunk sewer and facility of regulating and storing.
Background technology
Current social, Development of Urbanization is more and more rapider, and the area in city is increasing, and urban drainage pipe network structure is more next
More complicated, the processing pressure of urban water-body processing system is increasing.
Traditional urban pipe network system is all to be responsible for a piece of very big watershed using a big rain processing system,
Because watershed is excessive, time delay of the rainwater on pipeline or rainwash is not fully taken into account, causes rain at initial stage
Water and later stage rainwater largely mix.For example, storage pond has been built in certain city in the area close to urban sewage treatment system, it is assumed that
Urban rainwater of the M areas in storage pond 1Km, M areas is directly discharged to storage pond by pipe network, at the beginning of the city in M areas
The time that phase rainwater is fully discharged into storage pond is T1.For beyond the area apart from storage pond farther out in the region, it is assumed that N
Offset is 10km from the air line distance of storage pond, and the time that city initial rainwater regional N is fully discharged into storage pond is T2, from
From the point of view of time length, T2 obviously will be far longer than T1.And after storage pond stores full, the rainwater exceeded begins to be automatically discharged into certainly
In right water body, since storage pond be T3 to the time of natural water discharge start to collect rainwater to.During actual motion, if only
Only take the rainwater emission behaviour in M areas into account, i.e. the early-stage rainwater in M areas can enter sewage disposal system by storage pond
The clean rainwater of intermediary and later stages can be discharged into natural water, it is necessary to which T3 is more than T1, once exceeding T3, storage pond is immediately to certainly
Right discharge into water, and now N areas flow to the rainwater of storage pond and still pollute very serious early-stage rainwater, i.e. T3 is less than T2, to
Natural water discharge can undoubtedly cause very serious pollution.
If only the rainwater emission behaviour in view of N areas, i.e. T3 is more than T2, and the early-stage rainwater in that N areas can lead to
Cross storage pond to enter in urban sewage treatment system, handled well.But for M areas, M areas have largely
Later stage clean rainwater also storage pond discharge N area early-stage rainwater time in be discharged into municipal sewage plant,
Such emission behaviour can cause very big processing pressure to urban sewage system.In addition, M areas and N areas during actual motion
Pipe network be generally connection situation, due to the difference of distance, the delay effect on road, the early-stage rainwater in N areas may be tight
The later stage clean rainwater in heavily contaminated M areas, also results in the unreasonable of rainwater emission behaviour.
At present, a kind of technical scheme to solve the above problems has been proposed in the prior art, i.e., by using burst at
The mode of reason is repartitioned to urban pipe network system according to unit area, but for using burst processing by the way of to city
During city's pipe network system is divided by unit area, in particular for the division of some old towns, in unit area
It is that the trunk sewer set can not meet the emission request of rainy day sewage in the unit area in domain, in face of such situation,
Sanitary sewage and rainwater under trunk sewer receiving not can only be emitted on the natural water of distal end by Storm-water sewer.At this moment just need
Sewage-catching case is laid in urban pipe network system again to contain, temporarily substitute the effect of trunk sewer, alleviate trunk sewer to sewage
Carrying capacity.But such pipe network system is generally applicable under fine day state, when rainwater comes, due to dirty in pipe network
The disposal ability of water treatment plant is limited, and the maximum stream flow that sewage-catching case is contained is limited；When occurring for heavy rain, heavy rain, can not in time by
Water body in each unit region is arranged to sewage treatment plant simultaneously, causes going out for waterlogging disaster different degrees of in each unit region
It is existing.
The content of the invention
It is each in drainage system it is an object of the invention to provide being controlled during a kind of rainfall in order to improve the deficiencies in the prior art
The method that the sewage that section is cut in dirty pipe imports trunk sewer and facility of regulating and storing.This method is applied to each section during rainfall and flowed into
It is manageable that the sewage total amount of trunk sewer is more than trunk sewer can circulate this moment maximum stream flow and/or sewage treatment plant
Maximum capacity, methods described targetedly can fast and effectively discharge the water body in the region with different pollution levels
Processing.
