Description

Controlled during a kind of rainfall in drainage system in each section rainwater pipeline and plumbing drain Sewage import trunk sewer method
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 sewage in area's rainwater pipeline and plumbing drain imports trunk sewer.
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 Area is 10km apart 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 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 In natural water, since storage pond be T3 to the time of natural water discharge start to collect rainwater to.During actual motion, if 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.And for having to be discharged into sewage The flow that sanitary sewage in the plumbing drain for the treatment of plant can be discharged into sewage treatment plant certainly will be restricted, if waterlogging occurs Phenomenon, then the pollution in region is greatly improved.
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 current pipe network system be generally applicable in Under fine day state, when rainwater comes, because the disposal ability of sewage treatment plant in pipe network is limited, the maximum excessively stream of trunk sewer Measure limited;, can not be in time by water body (such as sanitary sewage, the early-stage rainwater in each unit region when occurring for heavy rain, heavy rain With middle and later periods rainwater) while arrange to sewage treatment plant, cause the appearance of waterlogging disaster different degrees of in each unit region.
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 sewage in section rainwater pipeline and plumbing drain imports trunk sewer.This method is applied to each section stream during rainfall Entering the sewage total amount of trunk sewer can be handled more than the maximum stream flow and/or sewage treatment plant that trunk sewer can circulate this moment Maximum capacity, methods described targetedly can fast and effectively arrange the water body in the region with different pollution levels Put processing.
The present invention seeks to what is be achieved through the following technical solutions:
Control the sewage in drainage system in each section rainwater pipeline and plumbing drain to import sewage during a kind of rainfall to do The method of pipe, the drainage system include according to region division multiple sections, the rainwater pipeline and plumbing drain of each section, The sewage pipe and trunk sewer that cut dirty pipe, be connected with plumbing drain being connected with rainwater pipeline;Described section of dirty pipe, sewage pipe It is connected respectively with trunk sewer, the drainage system end (i.e. the end of trunk sewer) is connected with sewage treatment plant;
Assuming that the maximum stream flow of the actual receptive rainwater of system end (i.e. trunk sewer end) is Q, then Q takes (Q1- Q3) and the minimum value in (Q2-Q3), wherein, Q1 is the maximum stream flow that sewage treatment plant can handle sewage, and Q2 is trunk sewer Maximum stream flow, Q3 be sewage pipe flow;
Methods described includes:
1) when rainfall, the flow for cutting dirty pipe of each section is controlled, is equal to the flow of the rainwater of trunk sewer end Q, the control method select one kind in following method:
