Description
Technical field
The utility model relates to a kind of biological arresting device for the treatment of rainwater.
Background technology
In recent years, the rainwater runoff pollution in China's major part city is comparatively serious, has become the primary factor of urban rivers and lakes water quality deterioration.City rainfall runoff management is all significant to the problem such as shortage of water resources, flood, pollution of area source solving city, receives international extensive concern in recent years.Traditional sewerage system design is that this design exists many drawbacks with the eliminating as early as possible of rainwater for fundamental starting point.Seeking the city rainfall runoff control measures how meeting environment, ecology, economic dispatch multiple benefits, is one of current city administrative institute facing challenges.
As a technology in urban storm kind of Best Management Practices (BMPs), biological delaying basin (also known as Rain Garden) not only can effectively cut down runoff and flood peak, and effectively can improve the water quality of rainfall runoff.Biological delaying basin becomes one of the most effective and most widely used urban storm BMPs fast in the U.S. and other developed countries.In view of biological delaying basin is in the managerial good result of city rainfall runoff, a lot of country has started to launch more extensive research to it at present, and how to improve its ability improving rainfall runoff water quality one of focus becoming this area research, but the research of this aspect is at present also very limited on the whole.
Utility model content
For solving above-mentioned Problems existing, the purpose of this utility model is to provide a kind of biological arresting device for the treatment of rainwater, rainwater is processed by the vegetation filtration of plantation and the infiltration (dripping) of filtering medium such as loamy sand, rainwater is excessively loose by soil, pollutent is by fine filtering material capture, absorption and bio-absorbable, can lawn be arranged on, motorway intermediate isolating band, parking lot etc., receive and filter the rainwater in lawn and waterproof region.
For achieving the above object, the technical solution of the utility model is:
For the treatment of a biological arresting device for rainwater, comprising: the filtering layer from top to bottom set gradually, layer of sand and gravel bed; Described filtering layer is mixed to form by sand, mud, clay and organism; Described filtering layer upper surface both sides are formed domatic respectively to extension, the domatic gradient is 30 ~ 45 °; Described filtering layer upper surface and domatic upper all kind are implanted with vegetation; Also comprise a conduit pipe, be arranged at inside described gravel bed, and one end extends to outside described gravel bed; Described conduit pipe tube wall offers some through holes.
Further, bottom described gravel bed and sidewall be also coated with impervious formation.
Again, bottom described impervious formation higher than groundwater level at least 0.3m.
Further, described gravel bed thickness is 0.15 ~ 0.2m.
And described gravel bed is made up of rubble or beans gravel.
Separately, described filtering layer upper surface two side slope length is 1 ~ 3m, and domatic height is 0.2 ~ 0.5m.
Separately have, described filtering layer thickness is 0.4 ~ 0.7m.
And described layer of sand is made up of aggregate.
Separately, the thickness >=0.1m of described layer of sand.
The utility model beneficial effect is:
Filtering layer is set, pollutent fine filtering is provided and supports vegetation growth.Soil particle can pass through some extra pollutents of cation exch ange adsorption, and soil particle can store a part of rainwater.The domatic setting of filtering layer upper surface both sides, can extend the residence time, contributes to controlling the flow velocity of water by filtering layer, thus increases by the total amount of straight-flow system process rainfall runoff.
Accompanying drawing explanation
Fig. 1 is the biological arresting device structural representation for the treatment of rainwater described in the utility model embodiment.
