Efficient integrated sewage treatment system

Abstract

The invention provides an efficient integrated sewage treatment system comprising a filter tank, an anaerobic tank, an aerobic tank and a purification tank, wherein the filter tank and the anaerobic tank are connected by a first communication pipe, the anaerobic tank and the aerobic tank are connected by a second communication pipe, the aerobic tank is connected to the purification tank through athird communication pipe, a water inlet is arranged on the upper portion of the side of the filter tank, a drain outlet is arranged on the lower portion of the water inlet, a linear motor is fixedly mounted on the top of the filter tank, and a push rod of the linear motor passes through the top of the filter tank, and is fixedly connected to a filter screen plate. The fine mesh filter screen platein the filter tank can filter solid pollutants in a suspended state in sewage, the fine mesh filter screen plate can realize automatic backwash cleaning without disassembly, and does not affect normal sewage treatment, the sewage treatment efficiency is improved, and an anaerobic biofilm in the anaerobic tank can remove organic pollutants in colloid and dissolved states in the sewage.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an efficient integrated sewage treatment system. Background technique [0002] At present, more than 50 million tons of domestic sewage are directly discharged in rural areas of our country every year, causing pollution to rivers and ponds. Compared with cities, the infrastructure construction in rural areas of our country is relatively backward, the living environment is poor, and environmental safety hazards and problems It is relatively prominent and seriously affects the living environment and health of rural residents. [0003] In addition, due to the small and scattered intermittent discharge of rural sewage, the high concentration of nitrogen and phosphorus, and a large number of bacteria and viruses have brought certain difficulties to the collection and treatment of rural sewage. However, current sewage treatment technologies such as activated sludge ...

Problems solved by technology

[0003] In addition, due to the small and scattered intermittent discharge of rural sewage, the high concentration of nitrogen and phosphorus, and a large number of bacteria and viruses have brought certain difficulties to the collection and treatment of rural sewage

However, the current sewage treatment technologies such as activated sludge and artificial wetlands are not suitable for rural sewage treatment due to factors such as high investment, large area, complex operation, and high personnel management requirements.
