Description
Technical field
The present invention relates to rainwater preconditioning technique field, be specifically related to a kind of based on combined system pipe networkRainwater division treatment system.
Background technology
Current social, Development of Urbanization is more and more rapider, and the area in city is increasing, cityStorm Sewer Network structure becomes increasingly complex, and the processing pressure of urban rainwater treatment system is increasing.At present, Urban Rainwater Pipe Networks is divided into three kinds: separate system, combined system and mixed flow system.
As shown in Figure 1, it adopts a large rain to traditional combined system pipe network rain processing systemWater treatment system is responsible for the watershed that a slice is very large, because watershed is excessive, not fullyConsider and the time delay of rainwater on pipeline or rainwash cause early-stage rainwater and later stageRainwater mixes in a large number. For example, certain city has been built in the area near urban sewage treatment systemStorage pond, supposes that M area is apart from this storage pond 1Km, and the urban rainwater in M area passes throughPipe network is directly discharged into storage pond, and the city early-stage rainwater in M area is fully discharged into storage pondTime is T1. For the distance storage pond area far away that exceeds this region, suppose N areaBe 10km apart from the air line distance of storage pond, the city early-stage rainwater in N area is fully discharged intoThe time of storage pond is T2, and from time length, T2 obviously will be far longer than T1. And work asStorage pond is collected has expired after early-stage rainwater, and the rainwater exceeding just starts automatic-discharging to natural waterIn, storage pond from start to collect rainwater to the time starting to natural water discharge be T3. RealWhen border is moved, iff the storm-water drainage situation of taking M area into account, the i.e. initial stage in M areaRainwater can enter into the clean rainwater of sewage disposal system intermediary and later stages by storage pond and can arrangeBe put in natural water, need T3 to be greater than T1, once exceed T3, storage pond is immediately to natureWater body discharge, and the rainwater that now N area flows to storage pond still pollutes very serious initial stage rainWater, T3 is less than T2, can cause undoubtedly very serious pollution to natural water discharge.
Iff the storm-water drainage situation of considering N area, T3 is greater than T2, that N groundThe early-stage rainwater in district can enter into urban sewage treatment system by storage pond, obtains fineProcessing. But for M area, M area has a large amount of later stage clean rainwaters also to existIn the time of the early-stage rainwater in storage pond discharge N area, be discharged into urban sewage treatment systemIn, such emission behaviour can cause very large processing pressure to urban sewage system. In addition,When actual motion, the pipe network in M area and N area is generally connection situation, due to distance notWith, the delay effect on road, the early-stage rainwater in N area may severe contamination M areaLater stage clean rainwater, also can cause the unreasonable of storm-water drainage situation.
Because first rain mixes in a large number with later stage rainwater, if realization is to this region early-stage rainwaterRegulate and store completely, need to build a bulky large-scale storage pond 8, cause high cost,Its effect of regulating and storing also reduces greatly due to the mixing of first rain and later stage rainwater.
Some place also arranges multiple storage ponds rainwater is processed, but the quantity of storage pond existsWhile setting, do not consider poor problem of concentration time between aforementioned far point and near point, therefore its first rainStill have a large amount of phenomenons of mixing with later stage rainwater, rainwater treatment effect and economic benefit are stillUndesirable.
