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.At present, Urban Rainwater Pipe Networks are divided into three kinds:Separate system, conjunction Stream system and mixed flow system.
Traditional combined system pipe network rain processing system is as shown in figure 1, it uses a big rain processing system to be responsible for A piece of very big watershed, because watershed is excessive, rainwater is not fully taken into account on pipeline or rainwash Time delay, early-stage rainwater and later stage rainwater is caused largely to mix.For example, certain city is close to the ground of urban sewage treatment system Area has built storage pond, it is assumed that urban rainwater of the M areas in storage pond 1Km, M areas is directly discharged to adjust by pipe network Reservoir, the time that city initial rainwater regional M is fully discharged into storage pond is T1.For beyond the region apart from storage pond Area farther out, it is assumed that N areas are 10km apart from the air line distance of storage pond, and the city initial rainwater in N areas is fully discharged into The time of storage pond is T2, and from the point of view of time length, T2 obviously will be far longer than T1.And being collected when storage pond has expired early-stage rainwater Afterwards, the rainwater exceeded begins to be automatically discharged into natural water, storage pond since start collect rainwater to natural water The time of discharge is T3.During actual motion, if only the rainwater emission behaviour for taking M areas into account, i.e. the early-stage rainwater energy in M areas The clean rainwater of sewage disposal system intermediary and later stages is enough entered by storage pond can be discharged into natural water, it is necessary to which T3 is big In T1, once exceeding T3, storage pond immediately discharges to natural water, and now N areas flow to the rainwater of storage pond and still polluted Very serious early-stage rainwater, i.e. T3 are less than T2, and very serious pollution can be undoubtedly caused to natural water discharge.
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 urban sewage treatment system In, such emission behaviour can cause very big processing pressure to urban sewage system.In addition, M regional with N during 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 early-stage rainwater in N areas may The later stage clean rainwater in serious pollution M areas, also results in the unreasonable of rainwater emission behaviour.
Because first rain largely mixes with later stage rainwater, if to realize regulating and storing completely to the region early-stage rainwater, need Build a bulky large-scale storage pond 8, cause cost too high, its regulate and store effect also due to just rain and later stage rainwater it is mixed Close and substantially reduce.
Some places are also provided with multiple storage ponds and rainwater are handled, but the quantity of storage pond does not consider when setting Between foregoing far point and near point the problem of concentration time difference, therefore its first rain still has showing of largely mixing with later stage rainwater As rainwater treatment effect is still undesirable with economic benefit.
