This utility model solves its technical problem and be the technical scheme is that a kind of domestic sewage in rural areas integral type processes device, including anaerobic tank, grille well, anaerobic pond, air-blast device, sedimentation tank, continuous filter, wet well, drain pipe, contact-oxidation pool, filler and regulating reservoir;Described anaerobic tank is connected with grille well by pipeline, described grille well adopts brick mix structure, grille well is connected with regulating reservoir by pipeline, described regulating reservoir is connected with anaerobic pond by pipeline, described anaerobic pond is connected with contact-oxidation pool by pipeline, in described contact-oxidation pool, filler is installed, filler is provided with aeration tube on bottom surface, described air-blast device is connected with aeration tube by pipeline, described packing volume is the 75% of catalytic oxidation pool volume, described heavy determine pond and pass through pipeline and be connected with contact-oxidation pool, described continuous filter is by cell body, top layer, water distribution layer, filter layer, water inlet pipe, sealing coat, impervious barrier and outlet pipe composition, it is provided with top layer near top in described cell body, described top layer is connected with water distribution layer, described cell body side is provided with water inlet pipe near top and connects with water distribution layer, described continuous filter is connected with sedimentation tank by water inlet pipe, described water distribution layer is connected with filter layer, described filter layer is connected with sealing coat, described sealing coat is connected with impervious barrier and is positioned at bottom cell body, described outlet pipe is arranged on cell body sidewall near bottom, described wet well is connected with continuous filter by outlet pipe, described wet well sidewall is provided with drain pipe。
As preferably, described continuous filter mesexine thickness is 400mm, is made up of fertile planting soil, it is planted and is implanted with flower, grass and crops。
As preferably, in described continuous filter, water distribution layer thickness is 300mm, is made up of Semen Benincasae sheet。
As preferably, in described continuous filter, sealing coat is made up of the non-woven fabrics of porous。
Operation principle: first peasant household's sewage enter people's anaerobic tank, sewage is through anaerobic digestion, and Organic substance therein obtains decomposed, reduces pollutant burden, improves the content of available nutrient in sewage;Fecal sewage after anaerobic tank and other sanitary sewages are delivered to grille well through gravity pipe line, and grid intercepts floating thing thick in sewage, and the water pump in protection later process pond is without prejudice;Then sewage person who lives in exile's regulating reservoir in the way of gravity flow, regulating reservoir has regulating pondage and the Effect of Pretreatment of hydrolysis acidification sewage concurrently, anaerobic pond is built with elastic filler, sewage overflows to biological contact oxidation pond again after anaerobic reaction, oxidation pond is built with elastic filler, and the Organic substance major part in sewage is removed at this;Sewage overflow after oxidation pond processes is to sedimentation tank, and sedimentation tank doubles as the distribution well of follow-up continuous filter;The processing stage of sedimentation tank water outlet penetration depth, i.e. continuous filter, act on through the filtration of pond interior-layer layer filler, absorption etc. at this stage effluent, final qualified discharge。
This utility model compared with prior art has the advantage that operation is simple and reliable, and cost is low, high treating effect, reduced investment, takes up an area few, simple to operate, convenient management, long service life and easy to maintenance。
