Rural sewage treatment is an important component of the sewage treatment industry in China, only sewage generated in the production and living processes is treated in relative cities and towns, and the rural sewage treatment is accompanied with environmental improvement and protection contents such as rural drinking water source area protection, rural domestic garbage treatment, livestock and poultry breeding waste resource utilization, pollution prevention and control and the like. However, the treatment of the sewage in rural areas in China is influenced by various factors such as economy, policy, living habits and the like for a long time, the treatment rate of the sewage in the rural areas in China is as high as 91.9 percent, the treatment rate of the sewage in the county and city reaches 85.2 percent, and the treatment rate of the sewage in the rural areas in China is only 11 percent by 2015. Therefore, how to treat rural sewage efficiently according to local conditions becomes one of the primary tasks of the current social development.
At present, the rural sewage treatment mostly adopts centralized treatment, and the technical method comprises the following steps: an artificial wetland treatment system and an underground soil infiltration and purification system based on the natural ecological principle, an aerobic biological treatment system and an anaerobic biological treatment system based on biological treatment. However, in rural areas with dispersed residents and complex landforms, the cost of infrastructure construction (pipe network construction) in the early stage of centralized treatment is extremely high, and the treatment of rural sewage treatment is severely restricted. Therefore, the utility model discloses a solve the difficult problem among the current rural sewage treatment process of remote, developed the small-size normal position sewage microbiological treatment technique based on half fixed bed technique. This device is through intaking in succession, under centimeter level load microorganism's spherical carrier fluidization, continuous treatment domestic sewage effectively improves sewage treatment efficiency, reduces domestic sewage treatment cost. This device is integrated device includes: a water inlet, a regulating tank, a facultative anaerobic reaction tank, an aerobic reaction tank, a disinfection device and a water outlet. The device is provided with a temperature control system, and a series of automatic operations such as temperature control, water inlet, water outlet and the like are realized through PLC program control. The device has the characteristics of simple structure, low cost, large processing capacity, energy conservation, high automation degree, easy operation, safety, reliability and the like.

The technical scheme of the utility model:
the utility model provides a half fixed bed normal position purifies domestic sewage device which characterized by: the device is of an integrated structure and consists of a water inlet, a regulating tank, a facultative anaerobic tank, an aerobic tank, a clean water tank and a water outlet; the adjusting tank, the facultative anaerobic tank, the aerobic tank and the clean water tank are connected through partition plates; the settling tank is arranged at the front end of the regulating tank, and the side wall of the regulating tank is provided with an impurity discharge port for discharging settled impurities out of the device at regular intervals; the facultative anaerobic pool is internally provided with clapboards, fillers loaded with facultative anaerobic bacteria float among the clapboards, the fillers float among the clapboards along with the change of water flow, the bottom of the aerobic pool is provided with a gas distributor for continuously supplying oxygen to the aerobic pool, and simultaneously, the fillers loaded with microorganisms are maintained to be fluidized; a submersible pump is arranged in the clean water tank, and the clean water tank is connected with the regulating tank through a pipeline and is used for partial reflux; the treated purified water is sterilized by an ultraviolet device at the tail part of the water purifying tank and then is discharged.
The BOD, TN and SS of the domestic sewage are not higher than 250mg/l, 70mg/l and 170mg/l respectively.
The filler is a compound which is synthesized by an incomplete hydrothermal method and is loaded on lignin by macroporous chitosan.
The utility model has the advantages and beneficial effects that:
the in-situ domestic sewage purification device has the characteristics of small occupied area, high treatment efficiency, low energy consumption, low cost, high degradation speed, easiness in operation, safety and reliability. The energy consumption of the device is effectively reduced through the overflow design; the equipment is dispersedly used for each farmer, the cost for laying sewage pipelines in rural areas can be effectively reduced, and the cost is reduced.
