Co-peasant household type sewage treatment plant

Abstract

The invention relates to a co-peasant household type sewage treatment plant which is characterized by comprising an anaerobic tank, an aerobiotic tank, an anoxic tank and a sedimentation tank which are connected with each other, the anaerobic tank and the aerobiotic tank are connected with each other, the aerobiotic tank is filled with second filler, the bottoms of the aerobiotic tank and the anoxic tank are communicated, the anoxic tank is filled with third filler; the middle-upper part of the anoxic tank is provided with a water outlet hole which is communicated with the sedimentation tank, the bottom of the anoxic tank is provided with an aeration device; the sedimentation tank is provided with a precipitation separation device, and a baffle area is arranged above the precipitation separation device. The co-peasant household type sewage treatment plant can purify and process domestic wastewater, operating cost is low, air can be charged only by a small air pump without any other power cost, a lot of energy consumption is saved, no specially-assigned person is needed for guarding, bottom sludge of the tank can be periodically cleared by a fecal suction truck, the co-peasant household type sewage treatment plant can be buried in the ground for use, and does not occupy ground space, the odor cannot overflow, and the co-peasant household type sewage treatment plant has no influence on the lives of the masses.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a combined household sewage treatment device. Background technique [0002] The rural water environment is not only the vascular system in rural areas, but also an important part of the national water environment. Domestic sewage is an important part of non-point source pollution in rural areas. Therefore, we must pay more attention to the problem of rural domestic sewage treatment, continuously improve infrastructure in the construction of new rural areas promoted by governments at all levels, and promote the coordinated development of economy, society and ecological environment. . [0003] The main characteristics of rural domestic sewage in my country are: (1) wide area, scattered and difficult to collect; (2) rapid growth rate of sewage volume; (3) low treatment rate. Taking the situation of rural pollution in a city in Zhejiang Province being treated by septic tanks as an e...

[0003] The main characteristics of rural domestic sewage in my country: (1) wide area, scattered, difficult to collect; (2) rapid growth of sewage volume; (3) low treatment rate

Take the rural pollution in a city in Zhejiang Province treated by septic tanks as an example, the treatment rate is only 13%, far exceeding the self-purification capacity of the water body; (4) lack of technical personnel in rural areas and weak economic strength, low level of maintenance and management

After the analysis of the current part of the rural sewage treatment mode, it is found that in the densely populated rural areas, the sewage flows into the terminal sewage treatment plant through the pipe network, and the investment in the pipe network accounts for about 70% of the total investment. The local area has caused great economic pressure; on the other hand, in areas with relatively sparse population distribution, domestic sewage has no treatment measures at all, and pollutants are discharged randomly, which seriously pollutes the rural ecological environment and directly threatens the health of farmers
