Description

A kind of sponge urban rainwater collection purification utilization integrated system
Technical field
The invention belongs to sponge urban construction and Rainwater Resources to utilize technical field more particularly to a kind of sponge city rain Water collecting, purifying utilizes integrated system.
Background technique
China be a water resource there is a serious shortage of country, according to statistics in national more than 600 seat cities, 50% or more city Water shortage, nearly 20% city serious water shortage.In recent years, with the high speed development of Process of Urbanization Construction, urban green space area gradually subtracts Small, the regions such as greenery patches, wetland, irrigation canals and ditches with water conservation function are largely evolved into hardened ground originally, and city is caused to exist Be only capable of when facing heavy rainfall by city planting ductwork drain, cause effectiveness factors to take place frequently, runoff pollution it is serious；And heavy rain later but The awkward situation of dry water shortage is fallen into, tropical island effect is significant.The phenomenon that " meet rain must flood, i.e. drought after rain ", is faced with city Ecology Two extreme: being on the one hand that urban waterlogging is serious, storm water man- agement becomes the security risk for influencing urban development；On the other hand it is then Most cities water shortage is serious, and water resource is supplied outside wretched insufficiency, especially dry spell serious water shortage and a large amount of rainwater of rich Pluvial The contradiction that row, drainage system can't bear the heavy load is got worse.
Sponge city refers to that city can have in terms of adapting to environmental change and reply as sponge Good elasticity, water suction, water storage, infiltration, water purification when raining, the water stored when needing discharged and be used.Sponge city Construction should follow the principles such as Ecology Precedence, and natural way is combined with artificial measures, ensure municipal drainage prevention waterlogging safety Under the premise of, realize that rainwater in the accumulation, infiltration and purification of urban area, promotes the utilization and ecology of rainwater resource to the maximum extent Environmental protection.An important sources of the rainwater as city water resource, recycle after rainwater-collecting is purified, can both mitigate city City controls flood and drains flooded fields pressure, reduces pipe-networks engineering construction cost；Again adjustable, supplement regional water.Sponge city is used as and repairs One paths of multiple city Ecology, can be realized water recycle and regeneration, save water, solve more and more The ecocrisis that the water environment that city is faced increasingly aggravates reduces break to the original water ecological environment in city to the maximum extent It is bad.
There are many shortcomings for conventional rainwater catchment system: conventional rainwater utilization technology is typically all to have single function Can, such as rainwater-collecting, rainwater purification function, without being connected good each comprehensive function well, and do not account for comprehensive intelligent pipe Reason, system fluctuation of service cannot adequately make good use of rainwater resource；Natural rain often largely carries a large amount of lifes on ground Rubbish and pollutant living, not purified rear rainwater are discharged into natural environment, can aggravate the pollution level of natural water；It encounters sudden and violent When rain, it will cause city overland runoff amount and greatly improve, city planting ductwork flood carrying capacity is much insufficient, causes road flood ponding； Conventional rainwater purification system often not from purification process is just considered when collecting rainwater, causes purification higher cost, purification efficiency It is low.
In summary, current Rainwater collection system has been unable to meet the demand of sponge urban construction, and therefore, having must Will in conjunction with the natural accumulation in sponge city, naturally osmotic, self-purification theory, developing a kind of can not only afforest and beautify city City's environment, but also can be relieved Urban Storm Flood pressure, drink up the rain in pollutant, to realize sponge Application of Urban Rain Water energy conservation Using and city surface source pollution control the Rainwater collection system with comprehensive function.
Summary of the invention
