Description

A kind of filter device for sponge city

Technical field

The utility model relates to sponge city technical field more particularly to a kind of filter devices for sponge city.

Background technique

Sponge city is new generation of city storm water man- agement concept, refers to that city is adapting to environmental change and reply rainwater band Natural calamity come etc. has good " elasticity ", also referred to as " water elasticity city ".International term is " low shadow Ring the building of exploitation storm-water system ".Water suction, water storage, infiltration, water purification when raining by the water stored " release " and are subject to benefit when needing With.Sponge city is built, plans as a whole to play natural ecology function and manual intervention function, effectively control rainfall runoff, realizes nature Accumulation, naturally osmotic, self-purification urban development mode, be conducive to repair city Ecology, self-restraint water resource, enhance city Prevention waterlogging ability expands public product effective investment, improves novel urbanization quality, promotes harmony between man and nature development.

Sponge urban construction should follow the principles such as Ecology Precedence, and natural way is combined with artificial measures, is ensuring city Under the premise of city's drainage waterlogging prevention safety, realize that rainwater in the accumulation, infiltration and purification of urban area, promotes rainwater to the maximum extent The utilization and ecological environmental protection of resource.Building sponge city is not to make a new start, and replaces traditional drainage system, but right A kind of Reduction of Students' Study Load and supplement of conventional drainage systems, farthest play the effect in city itself.In sponge Process of Urban Development In, the systematicness of natural precipitation, surface water and groundwater should be planned as a whole, coordinate each links of water circulation uses such as water supply, draining, and examine Consider its complexity and chronicity.

According to external experience, sufficiently utilization of the enhancing to rainwater, is an emphasis of sponge urban construction, in city Numerous buildings for, Collection utilization is subject to the rainwater for flowing through building, is the necessary means for building sponge city, and rainwater is wanted Want to be utilized, an essential step is exactly to filter, and only can just make up to needed for people rainwater by filtering Water quality requirement, currently, the urban architecture in China is designed general lack of rainwater catchment system, the rainwater used in sponge urban architecture Application is less in terms of filter device, some developed rainwater filtering devices also less combination building itself the characteristics of, still adopt With traditional water purification installation, it is difficult to meet the needs of sponge urban construction.

Summary of the invention

The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of filter device for sponge city.

In order to achieve the above object, the utility model adopts the following technical solutions: a kind of filter device for sponge city, Water process layer including being set to top of building and the preliminary filter at the top of water process layer, preliminary filter are the open coagulation in top Tu Chi, initial filter bottom of pond portion centre are swelled upwards, are successively arranged soil horizon, river sand layer, cinder layer and ovum from top to bottom in preliminary filter Rock layers, serike on soil horizon, boulder bed two sides of the bottom are equipped with downcomer, are equipped with sedimentation basin and ion exchange in water process layer Pond, sedimentation basin include that the adsorption tank of two sides and intermediate tank, adsorption tank are connected to water storage bottom of pond portion by sieve plate, adsorption tank Internal upper part also is provided with sieve plate, and the sieve plate of adsorption tank internal upper part is equipped with active carbon layer, and the bottom of downcomer is connected to active carbon layer, The top of the two sides adjacent with adsorption tank is equipped with several overflow holes on tank, and overflow hole converges into overflow pipe by pipeline, overflows Flow tube is equipped with suction pump, and overflow pipe is connected to the sewer pipe in building, drinking-water pipe is inserted in tank, is set on drinking-water pipe There is suction pump, the other end of drinking-water pipe is inserted into ion exchange pond, the non-quoted in the outlet pipe and building in ion exchange pond Middle water pipe connection, the outlet pipe in ion exchange pond are equipped with suction pump.

The sedimentation basin is concrete sump, and sieve plate is concrete sieve plate.

The sieve plate upper and lower of adsorption tank internal upper part is filled with sponge.

The beneficial effects of the utility model are: the utility model carries out layering using preliminary filter, then will through adsorption tank It is sent to tank after impurities in water absorption to be precipitated, the water after precipitating can be sent in non-quoted after ion exchange pond is handled It is utilized in water pipe, filter effect is good；The green percentage of building can be improved with serike on soil horizon, and reduced Building temperature, to reduce energy consumption；It is equipped with overflow hole at the top of tank, leads to tank spill-over when the force of rain is excessive When, in the sewer pipe of automatic overflow to building, if leaving speed not as good as rainwater dropping velocity, can also it start on overflow pipe Suction pump, accelerate draining.
