Description

Initial-rainwater treatment system
Technical field
Early-stage rainwater processing technology field is the utility model is related to, more particularly to a kind of initial-rainwater treatment system.
Background technology
Early-stage rainwater, as the term suggests rainwater when being exactly rainfall initial stage.Generally refer to ground 10-15mm thickness and form earth's surface The precipitation of runoff.Due to rainfall initial stage, rainwater has dissolved the dirts such as a large amount of sour gas in air, vehicle exhaust, plant gas Metachromia gas, behind ground of landing, and due to washing away roofing, asphalt concrete road etc. so that containing substantial amounts of in early stage rainwater Polluter, early stage, the pollution level of rainwater was higher, or even the pollution level beyond ordinary municipal sewage.Through rain pipe it is in line enter River course, a certain degree of pollution is caused to water environment.
Utility model content
The purpose of this utility model is to provide a kind of initial-rainwater treatment system, the pollutant in adsorbable early-stage rainwater Matter, reduce pollution of the early-stage rainwater to water environment.
Above-mentioned technical purpose of the present utility model technical scheme is that:
A kind of initial-rainwater treatment system, including separate tank, cyclonic separation equipment, collecting-tank and rapid filter, the separation Underground of the pond below rapid filter, the interior water pump being provided with for pumping water to cyclonic separation equipment of the separate tank, described point Water inlet end from pond connects rainfall pumping station wet well, the water side connection collecting-tank of the cyclonic separation equipment, the collecting-tank Water side connection rapid filter high water level end, the rapid filter low water level end connection rainfall pumping station.
By using above-mentioned technical proposal, the water of rainfall pumping station wet well is flowed into after separate tank to be divided by water pump into eddy flow From equipment, the cyclonic separation by cyclonic separation equipment will be sent into collecting-tank after the bulky grain debris initial gross separation in water, finally Rapid filter is fed the water into by collecting-tank, water flows into rainfall pumping station after rapid filter filters, is discharged into by rainfall pumping station in river.
Further, the upper end of the separate tank is provided with opening, and the opening is provided with well lid.
By using above-mentioned technical proposal, the setting of the opening of separate tank be for the ease of clearing up separate tank, Under normal circumstances, end cap is covered with opening, to avoid impurity from flying into separate tank.
Further, the cyclonic separation equipment is communicated with discharge pipeline.
By using above-mentioned technical proposal, the silt particle particle that cyclonic separation equipment separates is discharged into silt particle by the setting of discharge pipeline In collecting tank.
Further, fine sand graded filtering media layer is provided with the rapid filter and two above and below the fine sand graded filtering media layer The boulder bed of layer.
By using above-mentioned technical proposal, fine sand graded filtering media layer may filter that most COD, CH in water3- H and SS.
Further, the bottom of the rapid filter is communicated with backwash tube, and the high water level end of the rapid filter is communicated with instead Outlet pipe is rinsed, the high water level end is higher than the boulder bed.
By using above-mentioned technical proposal, rapid filter is poured water in rapid filter by backwash tube, can be by fine sand grading The impurity of absorption in filter material layer is gone out, and is discharged by backwashing outlet pipe, so as to realize the cleaning of rapid filter.
Further, current divider is provided with above the rapid filter, the current divider connects with the water side of the collecting-tank.
By using above-mentioned technical proposal, the setting of current divider, the water for flowing out collecting-tank more uniformly flows into fast filter Pond, improve the filter efficiency of filtering ponds.
In summary, the utility model has the advantages that:The water of rainfall pumping station wet well leads to after flowing into separate tank Cross water pump and enter cyclonic separation equipment, the cyclonic separation by cyclonic separation equipment is by after the bulky grain debris initial gross separation in water Collecting-tank is sent into, rapid filter is finally fed the water into by collecting-tank, water flows into rainfall pumping station after rapid filter filters, passes through rainwater Pumping plant is discharged into river.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but As long as all protected in the scope of protection of the utility model by Patent Law.
A kind of initial-rainwater treatment system, including separate tank 1, cyclonic separation equipment 2, collecting-tank 3 and rapid filter 4, separation Pond 1 is provided with the underground of the lower section of rapid filter 4, separate tank 1 to be used for the water pump 5 of water pump 5 to cyclonic separation equipment 2, separation The station wet well of water inlet end connection rainwater pump 5 in pond 1, the water side connection collecting-tank 3 of cyclonic separation equipment 2, the water outlet of collecting-tank 3 The high water level end of end connection rapid filter 4, the station of low water level end connection rainwater pump 5 of rapid filter 4.
In order to facilitate cleaning separate tank 1, the top of separate tank 1 is provided with opening 6, under normal circumstances, is covered with opening 6 End cap.Water pump 5 connect who dare to pass from the upper end side wall of separate tank 1 and connected with the water inlet end of cyclonic separation equipment 2.Rotation point Lower end from device equipment is communicated with discharge pipeline 8, and the silt particle isolated is discharged into collection vessel.
