Abstract
The utility model discloses an undercurrent type sewage treatment device using soil method. The device comprises a pebble bed (1), a tie bed (2), a sand bed (3) and a soil bed (4), wherein the pebble bed (1) is positioned at the bottom, the tie bed (2) is positioned above the pebble bed (1), the sand bed (3) is positioned above the tie bed (2), and the soil bed (4) is positioned above the sand bed (3); and the an influent water distributing pipe (5) is positioned at the interface of the pebble bed (1) and the tie bed (2), and the effluent water distributing pipe (6) is positioned inside the sand bed (3). The utility model can remove organic and inorganic pollutant in sewage, and the effluent water has quality meeting the requirements of 'quality standards for domestic service water' and can be recycled as recycled water.
Description
Technical field
The utility model belongs to the environmental protection equipment field, relates in particular to sewage treatment unit.
Background technology
Present processing for sanitary sewage, in cities and towns generally is to build sewage work, but it is big to build sewage work's investment, the working cost height, for the Economic development backward areas, especially the fragmentary samll cities and towns that distribute, residential quarters, tourist attractions and vast rural area etc., obviously building sewage work is unrealistic act.Sewage work adopts biological second-stage treatment in addition, and effluent quality is unsatisfactory, if water reuse in the conduct also must further be handled, its investment and working cost thereof are high especially.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of organic and inorganic pollutant of sewage can the removal that provide, effluent quality reaches " miscellaneous domestic water quality standard " requirement, can with it as in the undercurrent type land law waste disposal plant of water reuse.
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: undercurrent type land law waste disposal plant of the present utility model, comprise pebble bed, metalling, layer of sand, pedosphere, wherein: pebble bed is positioned at the bottom, metalling is on pebble bed, layer of sand is on metalling, and pedosphere is on layer of sand; The water inlet water distributor is positioned at pebble bed and metalling intersection, and the water outlet header is positioned at layer of sand.
The water inlet water distributor is a perforated pipe;
The water inlet water distributor is provided with the into dendritic pipe of water;
The water outlet header is a perforated pipe, wraps up in nylon wire outward;
Bottom of the present utility model is to adopt the plain concrete layer under the pebble bed, to prevent the effluent seepage polluted underground water; Periphery adopts brick wall, and the inboard is the finishing cement layer;
Well developed root systems such as pedosphere plantation reed, cattail, the plant that plant is tall and big.
The utility model compared with prior art, as can be known from the above technical solutions, by plant, filler to sewage adsorb, filtration, microbiological deterioration and plant-growth picked-up etc., purify waste water, reach the reclaimed water standard.Can efficiently remove the various organic and inorganic pollutant in the decontaminated water, to the BOD in the sanitary sewage
5, COD, SS clearance reach respectively more than 95%, 90% and 85%, to heavy metal, NH
3-N, TP, bacterium etc. also have good removal effect." integrated wastewater discharge standard " (GB8978-1996) one-level requirement is not only satisfied in the water outlet that obtains after the processing, and reaches " miscellaneous domestic water quality standard " (CJ25.1-89) index, can be all as in the water reuse.Not only handled sewage, and pollutent has been transformed, be used to improve the soil, supplied nutrients to growing plants.Have less investment, working cost low, need not special messenger's operational administrative, long service life.Can be widely used in cities and towns, domestic sewage in rural areas by using processing, especially be fit to side area and lack of water place backward in economy.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to embodiment, structure, feature and effect thereof according to the undercurrent type land law waste disposal plant that the utility model proposes, describe in detail as after.
Referring to accompanying drawing, undercurrent type land law waste disposal plant comprises pebble bed 1, metalling 2, layer of sand 3, pedosphere 4, and wherein: pebble bed 1 is positioned at the bottom, and metalling 2 is on pebble bed 1, and layer of sand 3 is on metalling 2, and pedosphere 4 is on layer of sand 3; Water inlet water distributor 5 is positioned at pebble bed 1 and metalling 2 intersections, and water outlet header 6 is positioned at layer of sand 3.
Water inlet water distributor 5 is a perforated pipe.
Water inlet water distributor 5 is provided with the into dendritic pipe 7 of water;
Water outlet header 6 is a perforated pipe, wraps up in nylon wire outward;
Bottom of the present utility model is that pebble bed adopts plain concrete layer 81 time, can cover one deck geotextile above, to prevent the effluent seepage polluted underground water; Periphery adopts brick wall 9, and the inboard is the finishing cement layer.
During use, sanitary sewage is by the pre-treatment of anaerobic pond (adopting septic tank usually), with wherein big suspended substance interception, the mud that precipitates digests, pretreated sewage enters water inlet water distributor 5 of the present utility model, enter pebble bed 1 and metalling 2, water outlet header 6 water outlets in the layer of sand 3 by the dendritic pipe 7 of intaking.The comparatively flourishing plant of plantation root system on the pedosphere 4, as: reed, cattail etc.
Device of the present utility model can be separately uses as a processing unit, also can be according to using by a plurality of combining as treatment system,
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
