Description
Technical field
The present invention relates to a kind of functional form Rain Garden suitable for sponge community, belong to rainwater runoff pollution control technology
Field.
Background technology
With the continuous quickening of Development of Urbanization, urban waterlogging, early-stage rainwater pollution and the black smelly problem in river course are more and more tighter
Weight.City internal water system is constantly reduced, and underlying surface Permeable stratum area increases, and causes rainfall runoff impenetrably to ooze under face, is formed
After ponding serious waterlogging is caused in urban inner.While rainfall runoff washes away road surface and carries high concentration heavy metal, hydro carbons
The pollutant such as organic matter and nitrogen phosphorus, can also cause early-stage rainwater pollution problem.There are some researches show the discharge of each pollutant makes
There is great variety in the water quality of urban rainfall runoff, pollutant concentration is significantly larger than the class of water environment quality standard V in runoff
Water, early-stage rainwater through drainage pipeline into severe contamination is caused after natural water, so as to aggravate the black smelly problem in river course.Urban waterlogging
With the development that early-stage rainwater runoff pollution problem has started to restrict China's economic, the enhancing rainwater stagnant storage that takes appropriate measures, under
Ooze and control runoff pollution of area source extremely urgent.
A large amount of rainwater are caused not obtain effectively based on traditional, large-scale Municipal Drainage Engineering control rainfall runoff
Recycle, cause water resource serious waste.And be based on it is low influence development technique rainwater control technology include ooze, it is stagnant, store,
Only, with, row etc. various methods, it is intended to flow mode and pollutant are reduced by scattered, small-scale Sources controlling and are contained
Amount, makes the hydrologic cycle of development area access expansion as far as possible.The common low influence development technique of urban construction includes permeable pavement, plants
Careless ditch and biological delay (Rain Garden) etc..Rain Garden is that a kind of rainwater of ecological sustainability is controlled and utilizes facility, can
Retention rainfall runoff, controls Modes for Urban Stormwater Runoff Pollution, moreover it is possible to beautifying city, purify air, it is easy to which landscape is combined, in sponge city
It is used widely in city's construction.
Rain Garden is to have soil infiltration concurrently and rainwater stores the depression of function, by plant absorption, microbial degradation and
Soil media filtration stores stagnant purifying rainwater, and is allowed to gradually penetrate into soil, recharging groundwater.Rain Garden is constructed by upper
And under be followed successively by coating, planting soil layer, aquifer and gravel layer.Function includes water and Water-quality control two parts:One side
Outer row's run-off is reduced by being detained cumulative effect flood peak clipping flow in face;On the one hand retained by plant and soil filtration is made
With control runoff pollution.But rain water pollutant is numerous, complicated component, soil is limited to the removal ability of pollutant, causes often
Rule Rain Garden is relatively low for the adsorption capacity of some high concentration heavy metals or organic matter, so that the water body containing pollutant is saturating
Cross soil filtering layer, layer of sand and enter underground water, cause underground water pollution.
Existing Rain Garden design mainly considers the stagnant peak effect of its retaining, and weakens catharsis, for initial stage rain
The contaminant removal capacity such as heavy metal, organic matter is limited in water, does not take effective intensive treatment means, there is pollutant and goes out
Water concentration is higher, again the problem of pollution cleaning water body.
The content of the invention
