NOVELTY - Rural domestic sewage treatment system comprises a sewage collecting pipe net, a sewage regulating pool, a sewage comprehensive reaction sediment pool, un-built or cancelled marsh gas pool and septic tank or integrated sewage processing device, where the substrate is paved in unit sewage collecting pipe network, each kitchen, bathing and toilet sewage, waste or mini-type waste and the substrate site is collective collecting filtered liquid to the sewage regulation pool outside substrate. The sewage regulation pool includes a water inlet pipe, a water outlet pipe.    USE - Used as rural domestic sewage treatment system.    DETAILED DESCRIPTION - Rural domestic sewage treatment system comprises a sewage collecting pipe net, a sewage regulating pool, a sewage comprehensive reaction sediment pool, un-built or cancelled marsh gas pool and septic tank or integrated sewage processing device, where the substrate is paved in unit sewage collecting pipe network, each kitchen, bathing and toilet sewage, waste or mini-type waste and the substrate site is collective collecting filtered liquid to the sewage regulation pool outside substrate. The sewage regulation pool includes a water inlet pipe, a water outlet pipe, used for regulating the water quality and water sewage; the sewage comprehensive reaction sediment pool comprises through an outside wall. The arc-shaped separate flow wall and round inner wall is divided into the anaerobic area, an anoxic zone, a facultative area, aeration area and settling zone and sand filter area; the anaerobic area is located in the sewage comprehensive reaction sediment pool and most inside, round inner wall inner side, the bottom anaerobic area is equipped with sewage water inlet pipe and sludge reflux tube. The inner wall of round toward one side the anoxic zone of the lower surface set with anaerobic area water outlet. The anaerobic area is designed with a conical upper cover. The upper cover is a conical top end provided with methane gas collecting pipe, anaerobic area is equipped with the sewage stirring device. The anoxic zone is located in the round inner wall and circular arc between separate flow wall; the anoxic zone is set with sewage stirring and pushing device; the facultative area is located in the round inner wall and between outside wall; the aeration area is located in the arc-shaped separate flow wall and between outside wall. The aeration area is set with aerator table, one aspect the following part of sewage to carry out aeration, on the other hand pushing sewage flow. The aeration area is equipped with regulate and control aeration system. The aeration system comprises regulate and control aeration tray, air blower and dissolve oxygen measurement regulate and control device. The aeration tray is set up with micro-pore and micro-pore type aeration disc. The aeration tray through aeration pipe is connected with air blower. The air blower is set with sewage comprehensive reaction precipitate in outside pool. The aeration of sewage water is set with low dissolve oxygen measuring device regulate and control. The dissolve oxygen measurement regulate and control device according to oxygen content regulate and control air blower working. The settling zone is located on an outside wall outer side. The aeration is end part, upper middle part, elliptical periphery wall is equipped with settling zone water inlet. The double end zone is equipped with the water outlet zone and water outlet zone is provided with to the third phase separator. The settling water outlet upper part is provided with an overflow dam settling bottom designed to cone structure. The lower end is cone structure with is set with sludge discharge valve. The sludge discharge valve is connected with rest sludge discharge pipe and sludge reflux tube. The sand filter area is located on outside wall outer side in the outer side zone. An INDEPENDENT CLAIM is also included for rural domestic sewage treatment comprising entering sewage through sewage pipe network into sewage regulating pool, regulating water quality and water quantity of sewage, after regulation, via sewage water inlet pipe entering into sewage comprehensive reaction sediment pool of anaerobic area, release degradable organic matter happen in anaerobic area, aminated function of organic nitrogen, and phosphorus and carry out the sewage stirring device of anaerobic area to avoid sludge sedimentation, anaerobic area generating the methane waste gas by anaerobic area top part of methane waste gas collecting pipe collecting use, the sewage after step anaerobic reaction by anaerobic area outlet entering into anoxic zone, sewage and pushing the anoxic stirring area device using the microorganism group and sewage in the full mixing, low in anoxic state, and organic matter as carbon source, in effect the denitrification fungus low nitrate nitrogen by reduction for nitrogen from water and then removing, by continuous flow sewage enter into facultative anoxic zone and the aeration area, full mixing in sewage in anaerobic zone, facultative fungus, heterotrophic fungus for preparing sewage and organic object further degradation, then mixed sewage after reaction under the action of stirring and flow at one device part enter into anoxic zone, one part entering into the aeration area, aeration disc and aeration step, set with micro-pore micro-pore aeration type, generating micro-bubble, and the dissolve oxygen measurement regulate and control device according to oxygen content regulate and control air blower working, ensure the dissolve oxygen in water at 2 mg/l, degrading organic matter in aeration, ammonia nitrogen oxidation for nitrate nitrogen and nitrite nitrogen, also generating phosphorus and absorb reaction, at end of the aeration area, a part of sewage flow into facultative area, a part of sewage entering into settling zone, the third phase separator is settling zone, realizing mud-water separation, sludge sunken to lower part zone under the action of gravity, where the sludge discharge valve through the bottom, discharging the sludge discharge valve, discharging the sediment one part sludge through sludge pipe reflux to reflux anaerobic area, as a part of rest sludge by rest sludge discharge pipe discharge, the sewage through overflow dam, outlet water pipe enter into sand filter area discharge standard after filtering the R rest sludge discharge pipe discharge the rest sludge dewatering after transporting.    DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram of the rural domestic sewage treatment process.
