Description
Technical field
The utility model relates to a kind of sewage treatment area, particularly relates to a kind of rural sewage treatment system.
Background technology
Along with improving constantly of China's life in the countryside level, and the development of the industry such as rural area livestock and poultry cultivation, aquaculture and agricultural byproducts processing, the dirt in villages and small towns, discharge of wastewater be the havoc eubiosis in rural area.But current stain disease administers still comparatively backwardness, and part township does not build sewage treatment plants, and sewage and rainwater enter interflow pipeline in the lump, enter river course nearby, makes river course, lake be subject to severe contamination, carries out sewage disposal extremely urgent.
Sewage disposal refers to the water quality requirement for making sewage reach a certain water body of draining or reuse, and to the process that it purifies.And in rural area because economic condition falls behind, use complicated Sewage treatment systems due to needs power wheel drive and long-time maintenance, cost can be made to improve, be not easy to the universal of Sewage treatment systems and promote.
Therefore those skilled in the art are devoted to develop a kind of structure rural sewage treatment system simple, with low cost.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of structure rural sewage treatment system simple, with low cost.
For achieving the above object, the utility model provides a kind of rural sewage treatment system, comprise biochemistry pool group and current wetland, the water side of this biochemistry pool group is connected to the feed-water end of current wetland, and the freeboard of this biochemistry pool group is higher than the water inlet height of current wetland, current wetland comprises the descending wetland of sewage of left side and the up wetland of sewage of right-hand part, separated by dividing plate between the up wetland of this sewage and the descending wetland of sewage, and the lower end of the lower end of the up wetland of this sewage and the descending wetland of sewage communicates, the descending wetland of this sewage is connected with the water side of biochemistry pool group, header is provided with in the up wetland of sewage.
Adopt said structure Sewage treatment systems, first through biochemistry pool group, organism is hydrolyzed country sewage by the biological purification of biochemistry pool group, acidifying and methanation, remove the organism in waste water, and improve the biodegradability of sewage, then automatically flow in the descending wetland of sewage of current wetland by height potential difference, from top to bottom through the purification of the descending wetland of sewage, then flow through in the up wetland of sewage by the lower end of dividing plate, slowly infiltrate from the bottom up again, through the further purification of the up wetland of sewage, finally collect out from header, as the utilization of follow-up water resources.Whole set process meets small towns and domestic sewage in rural areas requirement runs unpowered and that maintenance cost is almost nil requirement, and effluent quality effect is fine.
Preferably, the descending wetland of sewage and the up wetland of sewage comprise plantation soil layer, coarse sands layer, microbe stuffing layer and pebble bed from top to bottom all successively, and the volume of this microbe stuffing layer accounts for more than 1/3 of current wetland cumulative volume.
Preferably, microbe stuffing layer comprises minor diameter microbe stuffing layer and major diameter microbe stuffing layer, the filler diameter of this minor diameter microbe stuffing layer is less than the filler diameter of major diameter microbe stuffing layer, pebble bed comprises minor diameter pebble bed and major diameter pebble bed, and the cobble diameter of this minor diameter pebble bed is less than the cobble diameter of major diameter pebble bed.
Preferably, the top of the descending wetland of sewage is provided with perforation water distributor, and the feed-water end of this perforation water distributor is connected with the water side of biochemistry pool group, and this perforation water distributor is evenly distributed on the descending wetland of whole sewage.
Preferably, biochemistry pool group comprises the septic tank, anaerobic biofilter and the oxygen compatibility pool that are connected successively, the feed-water end of this septic tank is equipped with grid, the water side of this oxygen compatibility pool is connected to the feed-water end of current wetland, and the water inlet of this septic tank, anaerobic biofilter and oxygen compatibility pool is highly all higher than freeboard.
In order to improve the ventilation of oxygen compatibility pool, meet unpowered requirement, Unpowered ventilation device is equipped with at the top of oxygen compatibility pool simultaneously.
Preferably, in anaerobic biofilter, the volume of biologic packing material accounts for more than 80% of anaerobic biofilter useful volume.
The beneficial effects of the utility model are: the utility model adopts a whole set of unpowered systems to process country sewage, has good outlet effect.
