Abstract
The utility model relates to a city and town community rainwater treatment device. Water on roofs and on the ground is collected in a coarse filter (2) through channels, a filter channel (1) with 1-2 meters before rainwater enters the coarse filter is filled with medium particle filter rainwater materials (having the filter size of 4-7 mm), rainwater enters the coarse filer (2) through the filter channel, and then water in the coarse filter enters a well (3) which is internally provided with a separation wall below which a through hole is arranged to divide the well into an empty well and a chamber filled with fillings. The city and town community rainwater treatment device has the advantages that rainwater in city community can be totally treated, thereby avoiding polluted rainwater from being directly discharged into rivers, seas and lakes to influence the water quality of the rivers, seas and lakes; and meanwhile, the treated water can water lawns, flowers and trees, thereby effectively utilizing the rainwater and having obvious economic and social benefits for cities and towns in water-lacking regions.
Description
Technical field
The utility model relates to the rainwater processing technology field, and water is sub-district, a kind of cities and towns rainwater treatment device particularly.
Background technology
The rain water on roof and the ground rainwater of sub-district all do not carry out any processing now, naturally flow away, the pollutant of ground and roofing is all taken away by rainwater and is discharged to great river, river and lake like this, polluted environment, these rainwater are not effectively utilized simultaneously, and particularly drought and water shortage area rainwater runs off in vain, is not having also will to water lawn and flowers and trees with a lot of running water in the time of rainwater, cause the waste of water like this, cause very big pressure for the lack of water urban water.
Summary of the invention
The utility model is that research a kind ofly stores dmp filter, and then is used to water sub-district, the cities and towns rainwater treatment device that grass waters flowers and trees.
Sub-district, the utility model cities and towns rainwater treatment device, comprise: the water on the roofing, ground water all is pooled in the coarse filter 2 by irrigation canals and ditches, and rainwater enters the filter ditch 1 that is filled with medium grain (the filter footpath is 4-7mm) filtrate in the length ditch that one section 1-2 rice is arranged before the coarse filter, and rainwater ditch after filtration enters straining chamber 2, the water of coarse filter enters well 3 again, well is that a centre has partition wall, and there is port the partition wall below, and well is divided into two Room, one Room is empty well, and another chamber is filled with filler.
Filler granularity from bottom to top is descending, the orlop granularity is 10-20mm, thickness is 300-350mm, the last layer granularity is 7-12mm, and thickness is 300-350mm, and the last layer granularity is 5-10mm again, thickness is 200-250mm, last layer granularity is 2-7mm, and thickness is 200-250mm, is equipped with water pump 4 is housed in the filtrate pond, water in the well of the big back of rainwater is annotated certain altitude, water pump automatically starts and draws water, and by pipeline water is taken out to be spread across on the lawn or in the grove, to allow water be penetrated in the soil, allow soil contain more water, the water of sub-district carries out a benign cycle like this, when not raining, the water in the phreatic water can be extracted out and irrigate lawn and flowers and trees.
Be filled with filtrate in the coarse filter, filtrate makes progress particle diameter from large to small at the bottom of by the chamber, orlop particle diameter of filter medium 10mm-20mm, and upper strata particle diameter 8mm-15mm, the superiors are 5mm-10mm, and every layer thickness is 300mm, and top, coarse filter has delivery port, and delivery port links to each other with well.If service time is long, can wash with the method that recoil is scrubbed, very convenient.
The advantage of sub-district, the utility model cities and towns rainwater treatment device is: the rainwater of urban cells, can all be handled, avoiding contaminated rain water directly to be discharged into rivers sticks with paste marine, influence rivers, lake water quality, sewage after handling simultaneously can water lawn and flowers and trees, rainwater can be effectively utilized, more obvious to cities and towns, water-deficient area economical, societal benefits.
Description of drawings
Fig. 1 is sub-district, a cities and towns rainwater treatment device structural representation.
The specific embodiment
According to shown in Figure 1, water on the roofing, ground water all is pooled in the coarse filter by irrigation canals and ditches, and rainwater enters the filter ditch that is filled with medium grain (the filter footpath is 4-7mm) filtrate in the length ditch that one section 1-2 rice is arranged before the coarse filter, and rainwater ditch after filtration enters straining chamber, the water of coarse filter enters well again, well is that a centre has partition wall, and there is port the partition wall below, and well is divided into two Room, one Room is empty well, and another chamber is filled with filler.
Filler granularity from bottom to top is descending, the orlop granularity is 10-20mm, thickness is 300-350mm, the last layer granularity is 7-12mm, and thickness is 300-350mm, and the last layer granularity is 5-10mm again, thickness is 200-250mm, last layer granularity is 2-7mm, and thickness is 200-250mm, is equipped with water pump is housed in the filtrate pond, water in the well of the big back of rainwater is annotated certain altitude, water pump automatically starts and draws water, and by pipeline water is taken out to be spread across on the lawn or in the grove, to allow water be penetrated in the soil, allow soil contain more water, the water of sub-district carries out a benign cycle like this, when not raining, the water in the phreatic water can be extracted out and irrigate lawn and flowers and trees.
Be filled with filtrate in the coarse filter, filtrate makes progress particle diameter from large to small at the bottom of by the chamber, orlop particle diameter of filter medium 10mm-20mm, and upper strata particle diameter 8mm-15mm, the superiors are 5mm-10mm, and every layer thickness is 300mm, and top, coarse filter has delivery port, and delivery port links to each other with well.If service time is long, can wash with the method that recoil is scrubbed, very convenient.
