Description
Technical field
This utility model relates to rainwater preconditioning technique field, is specifically related to a kind of rainwater division based on combined system pipe network
Discarding system.
Background technology
Current social, Development of Urbanization is increasingly rapider, and the area in city is increasing, and urban rainwater web frame more comes
The most complicated, the processing pressure of urban rainwater processing system is increasing.At present, Urban Rainwater Pipe Networks is divided into three kinds: separate system, conjunction
Stream system and mixed flow system.
Traditional combined system pipe network rain water drainage system is as it is shown in figure 1, it uses a big rain processing system to be responsible for
The biggest a piece of watershed, because watershed is excessive, does not fully take into account rainwater on pipeline or rainwash
Time delay, early-stage rainwater and later stage rainwater is caused to mix in a large number.Such as, certain city is on the ground near urban sewage treatment system
District has built storage pond, it is assumed that M area urban rainwater in this storage pond 1Km, M area is directly discharged to adjust by pipe network
Reservoir, it is T1 that the city initial rainwater in M area is fully discharged into time of storage pond.For the distance storage pond beyond this region
Area farther out, it is assumed that the city initial rainwater that air line distance is 10km, N area of N area distance storage pond is fully discharged into
The time of storage pond is T2, from the point of view of time length, and T2 T1 to be far longer than.And collect when storage pond and expired early-stage rainwater
After, the rainwater exceeded begins to be automatically discharged in natural water, and storage pond is from starting to collect rainwater to starting to natural water
The time of discharge is T3.During actual motion, iff taking the regional rainwater emission behaviour of M into account, i.e. the early-stage rainwater in M area
The clean rainwater of sewage disposal system intermediary and later stages can be entered into by storage pond can be discharged in natural water, need T3
More than T1, once beyond T3, storage pond immediately discharges to natural water, and now N area flows to rainwater or the dirt of storage pond
Contaminate the most serious early-stage rainwater, i.e. T3 is less than T2, can cause the most serious pollution undoubtedly to natural water discharge.
Iff the rainwater emission behaviour in view of N area, i.e. T3 is more than T2, and the early-stage rainwater in that N area can lead to
Cross storage pond and enter in urban sewage treatment system, well processed.But for M area, M area has in a large number
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 the biggest processing pressure to urban sewage system.It addition, during actual motion M area and N ground
The pipe network in district generally connects situation, and due to the difference of distance, the delay effect on road, the early-stage rainwater in N area may
The later stage clean rainwater in severe contamination M area, also results in the unreasonable of rainwater emission behaviour.
Owing to first rain mixes in a large number with later stage rainwater, if to realize regulating and storing completely to this region early-stage rainwater, then need
Building a bulky large-scale storage pond 8, cause high cost, its effect of regulating and storing is also due to just rain and later stage rainwater mixed
Close and be substantially reduced.
Some place is also provided with multiple storage pond and processes rainwater, but the quantity of storage pond does not consider when arranging
The problem of concentration time difference between aforementioned far point and near point, therefore its first rain showing of yet suffering from later stage rainwater mixing in a large number
As, rainwater treatment effect is the most undesirable with economic benefit.

In technique scheme, described buoyancy tank room 14 inner bottom part is provided with buoyancy tank limited block 27.
This utility model rainwater enters accurate abandoned stream well by water inlet pipe 11, after mud chamber 13 is precipitated, overflows by first
Head piece the 19, second overfall 20 respectively enters buoyancy tank room 14 and float chamber 15.Buoyancy tank 17 and ball float 16 are by assembly pulley 103 phase
Even.Weight due to buoyancy tank 14 is more than the weight of ball float, and under original state, buoyancy tank 17 is in extreme lower position, and ball float 16 is in
High position (i.e. opening), if beginning to rain, then just rain can pass through abandoned stream pipe 18 abandoned stream.When rainfall is gradually increased, buoyancy tank
Water level in room 14 gradually rises, and reaches to stop abandoned stream water level, and now buoyancy tank 17 is issued to extreme higher position in buoyancy, and floats
Ball 16 reaches extreme lower position (i.e. closed mode).Owing to ball float 16 blocks abandoned stream passage 25, now rainwater can be in float chamber 15
Assembling, when in float chamber 15, water level is increased at outlet pipe 12, rainwater is discharged from outlet pipe 12, and now rainwater has become more
Totally, the effect of pretreatment has been reached.This device needs periodic maintenance, the mud in cleaning mud chamber.Wherein, the first overfall
19, the second overfall 20 openings of sizes ratio and stop abandoned stream water level, can be according to the volume settings of the first rainfall of different situations.
It is multiple small-sized abandoned stream wells 4 by whole pipe network region by stress and strain model, it is achieved the burst of rainwater is processed.This place
Reason mode is short due to pipe network route, and the acquisition time greatly shortening abandoned stream well 4 far point and near point rainwater is poor, it is therefore prevented that first rain
With the mixing of later stage rainwater so that the treatment effect of rainwater is the best.And rainwater can be carried out by each abandoned stream well simultaneously
Processing, rainwater treatment efficiency is greatly improved.
The above, detailed description of the invention the most of the present utility model, it is noted that any be familiar with those skilled in the art
Member in the technical scope disclosed by this utility model, the change that can readily occur in or replacement, all should contain at this utility model
Protection domain within.
