Device for treating dispersed sewage

Abstract

The invention discloses a device for treating dispersed sewage, which is composed of a box body, a cavity is formed in the box body; an inner cavity of the box body is divided into a sedimentation tank, a primary filter tank, a primary aerobic tank, an anoxic tank, a secondary aerobic tank, a phosphorus removal tank, a secondary filter tank and an adsorption clarification tank which are communicated in sequence by partition plates; a grid is arranged in the sedimentation tank; wherein a first filter sponge is arranged in the primary filter tank, a filler and an aeration disc are arranged in the primary aerobic tank, a filler and an automatic stirring device are arranged in the anoxic tank, a filler and an aeration disc are arranged in the secondary aerobic tank, pyrite is arranged in the phosphorus removal tank, a second filter sponge is arranged in the secondary filter tank, and ceramsite is arranged in the clarification tank. According to the device for treating the dispersed sewage,the sewage is sequentially subjected to sedimentation, primary filtration, primary aerobic treatment, anaerobic treatment, secondary aerobic treatment, phosphorus removal, secondary filtration and adsorption treatment, effluent of the sewage can be directly discharged or used for farmland irrigation, and the technical problem that existing rural dispersed sewage treatment does not reach the standard is solved.

Description

technical field

[0001] The invention relates to a device for treating dispersed sewage, and more specifically, relates to a device for treating dispersed sewage suitable for purifying rural dispersed sewage. Background technique

[0002] my country's rural area is vast, and rural sewage treatment is an urgent problem to be solved at present. The decentralized treatment mode of rural domestic sewage is an important part of rural water environment governance. The treatment of scattered sewage in rural areas or with small amounts of water must follow the principles of economy, high efficiency, energy saving and simplicity.

[0003] At present, the application of decentralized sewage treatment technology in rural areas in my country lacks norms and guidance, the market is chaotic, the industrial support capacity is weak, and the quality of facility construction is not high. It is difficult to collect decentralized sewage in remote areas, and centralized treatment is extremely u...
