Rural domestic sewage is large in quantity and wide in range, and a decentralized processing mode taking villages as basic units is generally adopted. Under the mode, the existing rural domestic sewage treatment process is characterized in that treatment process equipment of urban sewage treatment plants is directly miniaturized, and the specific process is mostly based on an activated sludge process and an improved process thereof, such as a membrane bioreactor and the like. The treatment system adopting the biological treatment process needs a plurality of energy consumption devices such as lifting water pumps, aeration fans and the like, and the energy consumption of the operation of the devices is high.

Therefore, a biological membrane method-based aerobic biological treatment system for village domestic sewage is needed to effectively remove organic matters, ammonia nitrogen and other reducing substances in village domestic sewage.
The existing aerobic biological treatment technology for rural domestic sewage is also continuously improved, the water-driven biological rotating disc is more suitable for aerobic treatment of rural domestic sewage and can replace the traditional air-blast aeration activated sludge aerobic biological treatment, but the water-driven biological rotating disc has more problems, such as more electromechanical equipment and high energy consumption under the drive of a multi-water pump. Moreover, the sewage used for driving and purifying is combined and reflows without considering the water quality difference of the effluent, and the preposed anoxic treatment effect is influenced. In addition, the problems that the sewage flow for driving and purifying does not consider accurate distribution, the torque provided by the driving waterwheel for rotating the rotating disc is insufficient, the sewage in the biological rotating disc tank body flows in a short time, the tail end return water and the water outlet proportion of purified water cannot be accurately controlled and the like seriously affect the aerobic treatment effect and the operation effect of preposed anoxic treatment are urgently needed, and the problems that a novel aerobic biological treatment system occupies a large area, has more electromechanical devices, is high in water pump fan energy consumption, is unstable in operation, is complex in maintenance and the like in village domestic sewage treatment facilities are solved.

The beneficial effect of this application lies in:
(1) Water drive biological rotating disk has adopted waterwheel and biological rotating disk disc of different diameters in this application, and the waterwheel of bigger diameter can provide bigger rotation driving moment of torsion for the biological rotating disk disc when rotatory, can load more biological rotating disk discs, reinforcing water drive biological rotating disk's purification efficiency. The design of the waterwheel with the large diameter can provide larger rotation torque, reduce the lifting amount of required driving water, reduce the using series of the water-driven biological rotating discs, save more energy and reduce less construction investment.
(2) The rivers flow direction in the rotating biological disk piece turns to unanimously with the pivot, and a plurality of baffling baffles are add to the centre, can make sewage flow time upper and lower baffling, and increase rivers flow increases the contact time of microbial film and sewage on the rotating biological disk piece, and the short stream phenomenon that appears when only can avoiding flowing through the surface can strengthen the good oxygen purification efficiency of quality of water of rotating biological disk piece.

The design of the adjustable water distribution ratio of the tail end water distribution tank solves the problem that the reflux ratio of the sewage after aerobic treatment is difficult to accurately control, and simultaneously meets the technical requirements of setting different reflux ratios in different seasons. Through the multi-point water distribution design of the top distribution pool and the tail distribution pool, the accurate control of the flow proportion of different positions is ensured, and the water channel flow distribution of the system is clearer and more controllable.
(4) The system adopts a multi-point backflow design that drives water and purified water to respectively flow back. The driving water is not purified by the aerobic nitrification of the biological rotating disc plate, and the driving water does not provide nitrate for denitrification, so that the driving water independently flows back to the tail end of the front-end sewage treatment unit through the water pipe to participate in lifting and purification again. And the return water distributed by the tail end distribution tank is rich in nitrate because of being treated by the biological rotating disc, and needs to flow back to the front end of the preposed sewage treatment unit to be mixed with the incoming sewage to carry out anoxic denitrification together. Therefore, the design of multi-point reflux of the system solves the contradiction that the driving water and the purified water have different water quality and can not flow to the same position, can better ensure the preposed denitrification and deodorization conditions, and ensures the stable operation of the system.
