Control the sewage that each section is cut in dirty pipe in drainage system to import during a kind of rainfall to adjust Store the method for facility
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 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.
