For this purpose, the utility model uses following technical scheme: a kind of dynamic filtration for rainfall regulative pool point From system, rainfall regulative pool front end is front side wall, and rear end is rear wall, it is characterised in that the dynamic filtration separation system passes through Moving guide rail is mounted in rainfall regulative pool, and filtering forebay, dynamic filtration are formed between dynamic filtration separation system and front side wall Filtering after-bay is formed between separation system and rear wall;Dynamic filtration separation system includes filtering filter cloth component, the filtering filter Cloth component is slidably connected by connector and moving guide rail formation;It is described filtering filter cloth component and rainfall regulative pool rear wall it Between setting filter cloth position adjust telescopic device.
Preferred embodiment according to the present utility model, moving guide rail include two groups be embedded in the middle part of the pool wall of conditioning tank two sides Upper rail and two groups of lower guideways.Preferably, the moving guide rail at a distance from front side wall be not less than pond body length 1/5, it is described Moving guide rail is not less than the 1/8 of pond body length at a distance from rear wall, to guarantee effective filtering of pond body.
Preferred embodiment according to the present utility model, moving guide rail use corrosion-resistant stainless steel or cast iron materials.
Preferred embodiment according to the present utility model, filtering filter cloth component filters flux should be not less than 4 ~ 8m3/m2/ h, it is mechanical Tensile strength is not less than 10Mpa, using the filter clothes such as polyester, polypropylene fibre, acrylic fibers, terylene or nonwoven cloth material.
Preferred embodiment according to the present utility model, filter cloth position, which adjusts telescopic device, to be fixed on adjusting pool wall for one end The telescopic adjustments facility such as spring, hydraulic regulation, air pressure adjustment.
The utility model has the beneficial effects that this system is in rainfall regulative pool by adding dynamic filtration separation system, with Gravity hydraulic pressure is motive force, the efficient crown_interception filtered using film, quick while store Adjusting rainwater water, efficiently go Except the suspended particulate contaminants in rainfall runoff, rainwater effluent quality is promoted, achievees the effect that water quality and quantity double control.Due to Effective filtering, the rainfall later period preferable rainwater of water quality can be obtained in Adjusting rainwater variable volume, the poor rainwater of rainfall initial stage water quality It can effectively store.

Specific embodiment
With reference to the accompanying drawing, and by specific embodiment the technical solution of the utility model is further illustrated.
As shown in Figure 1, a kind of rainfall runoff adjusts and contaminant removal system, including Adjusting rainwater stocking system, dynamic It is separated by filtration system, Stormwater Drainage System, filter back-flush system.Wherein Adjusting rainwater stocking system include rainfall regulative pool 1, Heavy mud groove 2, rainfall regulative pool 1 by filter cloth be divided into filtering forebay 1 ' and filtering after-bay 1 ' ', volume is according to coverage area It determines, certain slope is arranged in 1 bottom of rainfall regulative pool, and slope aspect sinks mud groove 2.Dynamic filtration separation system includes filtering filter cloth component 3, component moving guide rail 4, filter cloth position adjust telescopic device 5, and filtering filter cloth component 3 is made of filtering filter cloth and support construction, Component moving guide rail 4 by be embedded in adjust pool wall in totally four groups of guide rails form up and down, guide rail has connector to be connected with filter cloth component. Stormwater Drainage System includes rainwater water inlet pipe 6, rainwater outlet pipe 7, overflow discharge facility 8, sludge pipe 9, and wherein sludge pipe 9 is arranged Solenoid valve 10.Filter back-flush system is made of flushing pond 11, flush water pump 12, flushing pipe 13, flushing water nozzle 14.
The utility model to be protected is a kind of dynamic filtration separation system for rainfall regulative pool, rainfall regulative pool 1 Front end is front side wall, and rear end is rear wall, it is characterised in that the dynamic filtration separation system is installed by component moving guide rail 4 Filtering forebay is formed in rainfall regulative pool 1, between dynamic filtration separation system and front side wall, dynamic filtration separation system is with after Filtering after-bay is formed between side wall;Dynamic filtration separation system includes filtering filter cloth component 3, and the filtering filter cloth component 3 passes through Connector is slidably connected with the formation of component moving guide rail 4;Between filtering filter cloth component 3 and the rear wall of rainfall regulative pool 4 Filter cloth position is set and adjusts telescopic device 5.
As shown in Fig. 2, rainfall initial stage, filter cloth position adjusts telescopic device 5 and is located at diastole state, filters forebay volume at this time Minimum, since filter cloth does not generate blocking at this time, rainwater is from after water inlet pipe inflow, it can be achieved that the water level of the frontal pool rises rapidly, quiet Pressure acts on lower rainwater and quickly filters the filtering removal for realizing initial rainwater pollutant to after-bay discharge via filter cloth component 3.
As shown in figure 3, filter cloth gradually generates obstruction from the bottom to top, and filter cloth is in water as water inlet pipe adds up the increase of rainfall It is moved back under pressure effect along guide rail, the rate of filtration is gradually slack-off, and preceding pit level is gradually increasing.
As shown in figure 4, filter cloth blocking continues to increase, and filter-cloth filtering speed is less than rainfall when storm intensity continues to increase, Preceding pit level continues to rise, and when filtering the water level of the frontal pool rises to overflow pipe tube bottom position, volume reaches maximum, and filter cloth moves It moves to least significant end, adjusts telescopic device 5 and be located at most compressed state.Rainfall at this time is carried out except a small amount of filter cloth component by blocking Low velocity filter flows into outside filtering after-bay, and major part flow to drainage system downstream by overflow drain tube 8 and discharged, and realizes rainwater The control of run-off.
As shown in figure 5, with storm intensity reduction and taper off rainfall, filter in forebay at this time the rainwater that stores after The continuous filter cloth component low velocity filter by blocking to filtering after-bay simultaneously drains into downstream storm sewer, adjust at this time telescopic device 5 by Gradually restore, filter cloth component Forward, filtering forebay water gradually decreases.
As shown in fig. 6, being restored to when adjusting telescopic device 5 close to diastole state, filter cloth component is moved to close to front end, Filter cloth backwash is carried out at this time, and control flush water pump 12 starts, and will rinse the cleaning rainwater stored in pond 11 and passes through flushing pipe Road 14 is delivered at flushing water nozzle 14, so that the pollutant blocked on filter cloth flushing is fallen off by biggish washing pressure, and pass through The base slope of rainfall regulative pool 1 drains into heavy mud groove 2, and the solenoid valve 10 controlled on sludge pipe 9 is opened, and flushing waste water is made to drain into sewage Pipe network.After filter cloth backwashes, this system is returned to original state, and can be used for next rainfall.
It above are only the preferred embodiment of utility model.It will be appreciated by those skilled in the art that the utility model is not limited to this In the specific embodiment, be able to carry out various apparent variations for a person skilled in the art, readjust and substitution Without departing from the protection scope of the utility model.Therefore, although having been carried out more by above embodiments to the utility model Detailed description, but the utility model is not limited only to above embodiments, in the case where not departing from the utility model design, It can also include more other equivalent embodiments, and the range of utility model is determined by the scope of the appended claims.
