Method for treating village sewage and specific device thereof

Abstract

The invention discloses a method for treating village sewage and a specific device thereof. The specific device comprises a sump pump and a multifunctional deflection processing module connected with the sump pump. The multifunctional deflection processing module consists of three anaerobic units which are named Pool 1-3, two aerobic units which are named Pool 4-5, and a depositing unit named Pool 6; the pools are connected by pipelines. The anaerobic units are all provided with vent holes; the aerobic units are both provided with suspended upper and lower metal meshes; compartments between the metal meshes are filled with fillings; the lower layer of metal mesh is provided with a gas distributing hole which is connected with an aeration machine. The detailed operation steps of the method are described in the specification. The method and the specific device of the invention integrates physical processing techniques including depositing, filtering and the like, and biochemical processing techniques including anaerobic oxidation, aerobic oxidation and the like, thereby degrading organic substances in the sewage, fixing inorganic salt and reducing nutriment like nitrogen and phosphorus. The method and the specific device have the advantages of large hydraulic load and excellent processed water quality. Therefore, the method and the specific device are especially suited to national conditions of our country.

Description

technical field [0001] The invention relates to a sewage treatment device and method, in particular to a rural sewage treatment method and a special device thereof, specifically adopting a multifunctional baffle combined biological filter treatment method. Background technique [0002] For a long time, the problem of random discharge of domestic drainage, domestic garbage and agricultural waste in vast rural areas has not attracted fundamental attention. Most of the wastes such as human and animal manure, domestic garbage and domestic drainage have not been treated, and they are randomly piled on both sides of the road and beside the fields. Fields, ponds, ditches or directly discharged into water bodies such as rivers and canals, making "sewage splashing, garbage dumping, excrement piles, firewood stomping, livestock and poultry running around", "indoor modernization, outdoor dirty and messy" have become some A true portrayal of the rural ecological environment. According ...

AI Technical Summary

Problems solved by technology

However, rural domestic drainage is characterized by dispersal, small volume, far away from groups and large water bodies, small water environment capacity, and low management level. If these technologies are applied to rural domestic drainage treatment, there are still problems such as low pollutant removal flux and year-round operation. Technical bottlenecks such as instability, easy blockage of matrix filter material, poor phosphorus and nitrogen removal efficiency, high operating costs, or waste of land resources
