Abstract

The invention discloses a community wetland design, which relates to the field of recovery and treatment of part of domestic water and solves the problem of recycling of vegetable washing water. A river sand layer (2) 0.5-1m in thickness is arranged in the middle of soil (1) of a greening land in a community, the vegetable washing water passes through the river sand layer to be filtered prior to entering a drainage ditch, a drainage hole (6) is tilted by 45 degrees, and a hole on the wall of the drainage ditch is higher than a water outlet hole of the sand layer. Water in the drainage ditch is discharged to a water storage area (13) of a wetland area (11) in the community through a pipeline (14), and water in the water storage area (13) is filtered by river sand to enter a water body (15). Plants high in water resistance can be planted in river sand of the water storage area to absorb nutrients in the river sand, fishes can be cultured in the water body, and redundant water can be discharged through an overflow port (16) and used for flushing roads and dust on leaves. The river sand is the main soil texture at the bottom of the whole wetland, so that part of water can infiltrate underground to supply groundwater.

Description

Community's wetland design

Technical field

The present invention relates to the recycling field of part daily life sewage.

Background technology

The vegetable washing water great majority in kitchen enter sewage conduct now; Be mixed into sub-district septic tank or municipal sewage plant each other with other sanitary sewage; Make the water that itself does not have what pollution contaminated handle again, increase the burden of municipal sewage plant, the waste social resources.

Summary of the invention

Be the pressure, saving social resources and the minimizing environmental sanitation water that alleviate Wastewater Treatment Plant, the present invention collects the part vegetable washing water.

The technical scheme that the present invention solves its technical problem employing is: vegetable washing water is except that having part silt and a small amount of residues of pesticides; Basically there is not other pollutant, can be with environmental sanitation watering flushing road surface or flushing green plants leaf etc. are provided after the filtration of vegetable washing water through sand bed.

The invention has the beneficial effects as follows: reduce the environmental sanitation water, replenish underground water, the sub-district plant realized that deep layer is watered etc.

Wherein, 1, subdistrict greening land used soil property, 2, sand bed, 3, kitchen sink drain; 4, land use for greening ground, 5, aqua storage tank, 6, aperture 2cm drain hole, 7, the draining furrow bank; 8, aperture 1cm drain hole, 11, the wetland district, 12, the cement pool wall, 13, the storage area; 14, water inlet pipe mouth, 15, water body, 16, overfall gap, 17, Sha Qu.

The specific embodiment

The thick river sand layer 2 of soil property 1 intermediate arrangement one deck 0.5m-1m at the land use for greening of sub-district; The river layer of sand apart from 0.5m, is arranged an aqua storage tank 5 to land use for greening ground 4 in sand bed, vegetable washing water filters the back from gutter 3 entering aqua storage tanks 5 through the sieve aperture in 2mm aperture in the kitchen; Aqua storage tank 5 has cushioning effect; Avoid the untimely drainage pipe that causes of river sand infiltration to block, the drain hole 6 of the water of aqua storage tank 5 2cm from the aperture gets into sand bed 2, gets into effluent trough for avoiding silt; Drain hole 6 is made 45 degree, and the aperture of rhone is higher than the weep hole of sand bed.Water filters through husky in sand bed; Most of organic matters and part moisture retention are supplied land use for greening in sand plant absorbing utilization; Redundant moisture is through the drain hole 8 inflow gutters of the draining furrow bank 7 of land use for greening; Get into the gutter for reducing silt, drain hole 8 is designed to 45 degree, the sand bed aperture is lower than the aperture of cement wall.For promoting flowing of water, the position of aqua storage tank 5 is than the slightly high 10-20cm of draining furrow bank 7 at land use for greening edge.

The water in gutter enters into the storage area 13 in the wetland district 11 of sub-district through pipeline 14; The wetland area edge is designed to cement wall 12; Cement wall can supply the community resident rest that is seated, and storage area 13 is a pipe-line system or a ditch, and this pipe-line system has the drain hole under being tilted to; Be imbedded in the river sand 17, the water after filtering through river sand gets into water body 15.Can plant the strong plant absorbing of water resistance nutrient wherein in the river sand 17, water body can be breeded fish.Unnecessary water can be discharged through overfall gap 16, the floating dust that this part water can be used to sprinkle water and wash road, washes leaf.

The main soil property in the bottom of whole wetland is a river sand, utilizes the water permeability preferably of river sand, makes water be penetrated into underground additional underground water.

Claims

1. community of the present invention wetland design mainly is to filter the kitchen vegetable washing water through sand; Concentrate on then in the pond, it is characterized in that: the vegetable washing water in kitchen is through behind the 2mm strainer filtering, and the thick river sand layer of 0.5-1m that gets into land use for greening filters; The infiltration of part water replenishes underground water, green land is watered when filtering; A small amount of organic matter in the vegetable washing water can be detained and rots to plant nutrient to be provided, and filters redundant moisture and flows to the gutter, enters into the central water body of sub-district wetland then; Through effects such as river sand filtration, plant absorbing, water fish classes, water quality is further purified again.
