Abstract

The present invention relates to a processing unit suitable for scattered type rural sewage, and belongs to the field of environmental protection. The processing unit includes an anaerobic area, an aerobic area and a precipitation area; the three areas are in a combination structure formed by mutual nesting of three sleeves, the precipitation area, the aerobic area and the anaerobic area are arranged in turn from outside in, a three-phase separator is arranged on the top of the aerobic area and the anaerobic area, an exhaust pipe is arranged on the three-phase separator; an aeration device is arranged on the lower part of the aerobic area, the aerobic area and the precipitation area bottoms are communicated; the top of the precipitation area is provided with a ring water gathering area, the ring water gathering area is provided with water quality testing equipment, and the precipitation area bottom is a sludge gathering area. The processing unit has the advantages of being low in cost, simple and effective, high in degree of automation, and suitable for small enterprise to use.

Description

technical field [0001] The invention relates to a sewage treatment device suitable for rural scattered dwellings, which belongs to the field of environmental protection. Background technique [0002] With the development of the economy, the widespread use of pesticides and chemical fertilizers and the increase in the discharge of rural domestic sewage, a large amount of nitrogen and other biological nutrients are continuously discharged into rivers and lakes, which accelerates the degree of eutrophication of water bodies. At present, my country's rural sewage discharge is large and the effective treatment rate of sewage is low. The water area is seriously polluted, and the treatment is difficult to meet the national standard. [0003] Although our country has taken a lot of measures to solve the problem of rural water pollution, there are still some problems in terms of technical equipment, such as high infrastructure construction cost and operating cost, and treatment effici...
