Description
Technical field
The present invention relates to draining technology field is shunted, more particularly, to a kind of integration for seeping row based on sponge urban rainwater
System.
Background technique
With the continuous development of urbanization, certain environmental problem is brought to the life in city, such as urban waterlogging, initial stage rain
The problems such as water pollution, black-odor riverway.Process of Urbanization Construction is that greenery patches is reduced in city, and underlying surface hardening aggravates, and rainfall runoff adds
Speed, rainwater infiltration rate reduce, and increase urban inner System drainage pressure.Rain drop erosion road surface carries a large amount of pollutant, with
And industrial wastewater not qualified discharge, aggravate the black smelly problem of city river.With the proposition of sponge the idea of the city, can effectively delay
Solve High-speed Urbanization bring environmental problem.Sponge urban construction theory meets city ecology construction guideline, it is ensured that
Under the premise of Urban Waterlogging safety, realizes to the purpose of the water suction of rainwater, water storage, infiltration, water purification, follow the water stored when needing
Ring utilizes, and promotes the utilization and ecological environmental protection of water resource.
For traditional municipal drainage facility based on hard water channel, rainwater is exhausted directly to drainpipe, reduces the lower infiltration of rainwater, rain
Water does not have reasonable utilization, results in waste of resources.In order to improve the utilization rate of rainwater, with depression, ecological pool, pervious surface,
A series of greenery patches processing techniques such as Rain Garden carry out stagnant, storage, infiltration processing to rainwater, effective to promote rainwater cyclic utilization rate.
A kind of wherein green facility that Rain Garden is controlled and utilized as ecological sustainability rainwater has the function of infiltration, filter, storage, row etc.,
Rainfall runoff speed is reduced, rainwater infiltration filter is effectively improved, improves the utilization rate of rainwater, harmonizing nature precipitation, surface water, underground
The circulation of water, moreover it is possible to improve environment miniclimate.These technologies are controlled and are solved from rainwater source, and the destruction ring of minimum
Border.
Currently, rainwater and the general of surface water are discharged into storm sewer, or rainwater is discharged into after handling by Rain Garden
Pipeline, but there is also some shortcomings for these processing modes, first is that direct emission, increases municipal storm sewer and discharges pressure, increase
Urban waterlogging probability；Second is that rainwater can not bring pollutant by processing direct emission, water environment is destroyed；Third is that even if passing through
Existing Rain Garden technical treatment, without reasonable filtration system, the pollutant in rainwater is still higher, direct emission, again
Polluted source.
