Description
Technical field
The invention belongs to city surface source pollution control technology field, be specifically related to a kind of rain perforaled strainer that can be separated early-stage rainwater runoff.
Background technology
At present along with the continuous expansion of China's city size, there is huge change in land use pattern, occurred a large amount of waterproof ground, surface runoff coefficient enlarges markedly, and the run-off that Urban Rain is formed was much larger than the past.In rainfall, rainfall runoff washes away the one of the main reasons that city surface source pollution that road causes has become urban water-body water quality deterioration.Urban highway traffic load is large, and floor space is many, and the generation intensity of its non-point source pollution loading is greater than the waterproof underlying surface such as roofing, square, the key object that should control as city surface source pollution.Wherein, the rainfall initial stage defines first flush to road, and the Initial Runoff that early-stage rainwater is formed contains most roadway pollutants, as long as Initial Runoff and later stage runoff detachment can be processed separately, just can greatly reduce the contaminant capacity of road pollution of area source.
China's urban road both sides adopt rain perforaled strainer to add roadside greenbelt configuration mostly, the road rain water runoff formed in rainfall enters municipal wastewater pipeline through rain perforaled strainer, a large amount of road surface source pollutants enters municipal wastewater treatment plant with rainwater, the load of the Sewage Plant sewerage treatment of increasing and cost on the one hand.The ability of the rainwater purification of roadside greenbelt is not fully utilized on the other hand.If the effect process initial rainfall runoff of the pollutant purification of roadside greenbelt effectively can be utilized, the amount of rainfall entering city planting ductwork can be reduced on the one hand, reduce Sewage Plant water treatment load, the sewage clarification potential that can give full play to roadside greenbelt on the other hand absorbs the pollutant of degrading in Initial Runoff, effective reduction surface runoff coefficient also can processing section Runoff contaminants, effectively alleviates even to solve rainfall rainfall runoff and wash away the city surface source pollution problem that road causes.
Chinese patent literature CN2573582Y discloses a kind of city street antiblocking antifouling catch basin cover on September 17th, 2003, be made up of cage and several lids, its cage size and rainwater well head size match, and be designed with several leak-off chute, be equipped with heavy poly-groove on the side of leak-off chute, on each leak-off chute, be stamped the bar lid that one piece of area is greater than leak-off chute, the both sides, bottom of bar lid, is provided with supporting platform, make between bar lid and leak-off chute, to form watering slot and rest on cage.
Because the top mouth of leak-off chute is a little less than cage upper surface, heavy poly-groove is the groove on cage, covers the top mouth of leak-off chute, then prop up bar lid with supporting platform with bar lid, relies on the gap between bar lid and heavy poly-groove permeable.The advantage of this catch basin cover is: can stop foreign material rubbish blocking leak-off chute or blocking underground drainage pipe.But because the top mouth of leak-off chute is lower than cage upper surface, as long as rainwater flows through catch basin cover just can enter subsoil drain, it can not isolate early-stage rainwater and middle and later periods rainwater, cannot reduce the city surface source pollution that rainfall runoff causes.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of rain perforaled strainer that can be separated early-stage rainwater runoff, it substitutes existing trackside rain perforaled strainer, the Initial Runoff that can be contained a large amount of road surface source pollutants the initial stage causes roadside greenbelt, realize on the one hand being separated of initial stage road rain water runoff and middle and later periods runoff, the sewage clarification potential giving full play to roadside greenbelt on the other hand absorbs the pollutant of degrading in Initial Runoff, effective reduction surface runoff coefficient is energy processing section Runoff contaminants also, effective alleviation even solves rainfall rainfall runoff and washes away the city surface source pollution problem that road causes.
Solution of the present invention is realized by such technological means, it comprises concrete substrate and is located at the permeable mouth on concrete substrate, water gallery was offered in described permeable mouth both sides, and the bottom surface crossing water gallery is the upper surface of concrete substrate, and permeable mouth absolute altitude was greater than water gallery absolute altitude.
Because mouth absolute altitude permeable in the present invention was greater than water gallery absolute altitude, rainfall Initial Runoff carries most roadway pollutants and enters roadside greenbelt through water gallery, thus avoid early-stage rainwater and enter municipal pipeline, along with rainfall duration increases, rainwater on road surface runoff increases gradually, then rainwater covers rainwater gallery and enters municipal pipeline through permeable mouth, thus effectively achieves the shunting of early-stage rainwater runoff and middle and later periods rainfall runoff.
The technique effect that the present invention has is: the shunting realizing road Initial Runoff and middle and later periods runoff, reduce the sewage clarification potential that can give full play to again roadside greenbelt in rainfall while Sewage Plant rainwater treatment load and absorb the pollutant of degrading in Initial Runoff, effective reduction surface runoff coefficient also can processing section Runoff contaminants, effectively alleviates even to solve rainfall rainfall runoff and wash away the city surface source pollution problem that road causes.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As depicted in figs. 1 and 2, the permeable mouth 6 that the present invention includes concrete substrate 7 and be located on concrete substrate, water gallery 5 was offered in described permeable mouth 6 both sides, and the bottom surface crossing water gallery 5 is the upper surface of concrete substrate 7, and permeable mouth 6 absolute altitude was greater than water gallery 5 absolute altitude.
As depicted in figs. 1 and 2, crossing water gallery 5 two ends is arc charge for remittance mouth 4, is conducive to collecting the rainwater on road surface and releases early-stage rainwater to roadside greenbelt.
Above-mentioned concrete substrate 7 is the agent structure of rain perforaled strainer and main load-bearing unit.
As shown in Figure 3, after rainfall, due to the relation of road grade, the waterproof earth's surface of road 3 starts to form surface flow, the initial rainfall discharge series first souring on the waterproof ground of road, most of road surface source pollutants flows through water gallery 5 with initial rainfall runoff under the effect of road grade after the arc charge for remittance mouth 4 of rain perforaled strainer 2 of the present invention confluxes, avoid permeable mouth 6 enters roadside greenbelt 1.
Along with the increase of rainfall duration, road rain water run-off increases gradually, the water yield flowing through arc charge for remittance mouth 4 and mistake water gallery 5 increases until covered water gallery 5 gradually, then namely most middle and later periods rainfall runoff enters storm sewer through permeable mouth 6, thus achieves the shunting of rainfall Initial Runoff and middle and later periods runoff.
One aspect of the present invention realizes being separated of initial stage road rain water runoff and middle and later periods runoff, rainfall interception initial stage road runoff reduces Sewage Plant rainwater treatment load, the sewage clarification potential that can give full play to again roadside greenbelt on the other hand absorbs the pollutant of degrading in Initial Runoff, effective reduction surface runoff coefficient also can processing section Runoff contaminants, effectively alleviates even to solve rainfall rainfall runoff and wash away the city surface source pollution problem that road causes.
