Description

A kind of tandem road rain water runoff ecological purification system and its construction method
Technical field
The present invention relates to city ecology construction technical field, specifically a kind of tandem road rain water runoff ecological purification system System and its construction method.
Background technique
Pollutant includes suspended particulate substance, heavy metal, toxic organic compound, oil and rouge and nitrogen and phosphorus object in road runoff Deng each constituent harmfulness is larger.Suspended particulate substance itself is non-toxic, but its strong adsorption can carry venomous injurant with Water flow migration;Toxic organic compound belongs to artificial synthesized type organic (such as pesticide, Polychlorinated biphenyls, high molecular polymer) into water Body is not easy to be degraded by microorganisms and toxic be harmful to the human body;The nutriments such as nitrogen phosphorus, which enter water body, can make its eutrophication therewith can Bring a series of harm;Heavy metal contaminants only need it is micro can produce toxicity, and cannot be degraded by microorganisms, or even by its turn The compound for having bigger toxicity is turned to, and human body can be entered by food chain and cause chronic progressive poisoning.In rainfall and earth's surface diameter Washing away, entering receiving water body under conveying effect for stream, causes water quality deterioration.Research both domestic and external has shown that city overland runoff is As the second largest water body non point source of pollution for being only second to agricultural runoff, and second in addition to city domestic sewage and industrial wastewater Big city Pollutant Source in Aquatic Environment.
In recent years, with the fast development of national urbanization process, the increase of city Permeable stratum area leads to urban waterlogging It takes place frequently with underground water pollution phenomenon, is only asked by the road rain water water pollution that end-o f-pipe -control measure is difficult to solve to be faced at present Topic, more effective processing mode is to take initial stage control, the means that process blocks and end treatment combines, to road rain Water runoff pollution problem carries out comprehensive treatment.
And mesh road rain water more take abandoned stream or be directly discharged into storage water body mode handle, though can accelerate water flow row Out, but the effect blocked to pollution course cannot be played the role of, it is small to heavy metal in water and the abatement removal of nitrogen phosphorus.And meet heavy rain When be also unable to reach the effect for delaying peak runoff, a large amount of runoff rainwater lean on end measure to be handled entirely, will certainly cause end The overload operation for holding treatment facility is easy to cause waterlogging, pollutes water quality.
A kind of area of heavy rainfull face source sewage, which is disclosed, application No. is 201810801377.1 Chinese invention patent harvests use System and remodeling method, the invention carry out shunting of removing contamination using shunting well automatically, store and initial stage that reuse pollutant concentration is high The runoff later period runoff low with pollutant concentration, but when encountering heavy rain, irrigation canals and ditches short time inner product is full or stores appearance more than channel Product, the not purified water body that is directly discharged into of the water exceeded will form pollution.
Application No. is 201811286821.6 Chinese invention patents to disclose a kind of road surface rain for different pollution sources Water runoff discrete particles composite purification layer and its clean-up effect test method, composite purification layer is directed to different pollution sources, using two Kind or more different-grain diameter granular materials, mated formation with different pavement thicknesses, but its packing material size is single, thickness is less than normal, It is poor to cut big vast retention effect, it is poor to high pollution Initial Runoff treatment effect under storm intensity.
