It breaks out and opens up bring water pollution problem, had broad application prospects in road engineering.
But the control of existing rainwater runoff pollution object has the following deficiencies:
(1) most of is all the waste lump retained in rainfall runoff using boom net, seepage brick or meadow, but rubbish
Rubbish is easy to swim on meadow or before getting lodged in boom net, impacts to environmental beauty, and contaminant removal efficiency is low in rainwater, and
Soil is easy to be lost because of heavy rain, the poor filtration effect of turf and seepage brick；
(2) existing rainfall runoff much flows directly to municipal sewer or roadside, thus the water that directly permeates the ground, rainwater
Although large particulate matter is filtered by soil or stone in runoff, in rainfall runoff there is also certain organic matters soluble in water or
Toxic element, people use or quote by after the underground water of rainwater runoff pollution, can threaten to the life security of people, and rush
Brush roof, road rainwater in often carry harmful substance, when rainfall runoff floods meadow, will affect grass or tree growth ring
Border threatens to the ecological balance of nature.
Summary of the invention
In order to overcome the shortcomings of that prior art, the present invention provide a kind of ecology list of city rainwater runoff pollution object
First control method and device, equipment for separating liquid from solid is separated rubbish and rainfall runoff using the centrifugal movement of rainwater, to rainwater
Primary filtration purification efficiency is high, and using first rainfall runoff and bulky grain solid is separated, then aeration and biological pond first removes rainwater
The harmful substances such as phosphorus, nitrogen in runoff, removed finally by the photooxidation reaction in tertiary treatment pond, flocculation reaction phenol in water,
The design of cyanogen, sulfide, permeable layer has both filtered rainwater, also avoids soil erosion, can effectively solve that background technique proposes
The problem of.
The technical solution adopted by the present invention to solve the technical problems is:
