Integrated single-household domestic sewage purification device

Abstract

The invention relates to an integrated single-household domestic sewage purification device which comprises four stages of tank bodies which are integrally arranged, namely a first-stage anaerobic tank, a second-stage anaerobic tank, a third-stage facultative tank and a fourth-stage constructed wetland tank. The device comprises a first-stage anaerobic tank, a second-stage anaerobic tank and a third-stage facultative tank, and an anaerobic-anaerobic-anoxic three-stage septic tank structure is constructed, so that domestic sewage can be fully fermented; by arranging a four-stage constructed wetland pool with an opening in the top, a renewable adsorption matrix and planted wetland emergent water stain-resistant plants are arranged in the four-stage constructed wetland pool, and the effluentquality can be improved. The whole device is low in cost, convenient to transport, simple, practical and very suitable for rural single-household sewage treatment, and the field construction period isshortened.

Description

technical field [0001] The invention relates to the technical field of rural domestic sewage treatment, in particular to an integrated single household domestic sewage purification device. Background technique [0002] Domestic sewage in rural areas of our country is mainly treated by single households, and a single septic tank is widely used to purify domestic sewage. In order to adapt to the rural environment and conditions, most of the domestic sewage purification systems currently used are three-stage septic tank devices with simple structure and low cost. This device generates NH by anaerobic digestion of N-containing organic matter under anaerobic and anoxic conditions 3 and other odorous gases are directly emitted, affecting the comfort of the living environment. Moreover, the concentration of organic matter in the effluent is high, and the problem of black and odor is serious. Direct discharge will cause pollution of the receiving water body, and the breeding of mo...

Problems solved by technology

This device generates NH by anaerobic digestion of N-containing organic matter under anaerobic and anoxic conditions 3 Direct discharge of odorous gases, affecting the comfort of the living environment

Moreover, the concentration of organic matter in the effluent is high, and the problem of black and odor is serious. Direct discharge will cause pollution of the receiving water body, and the breeding of mosquitoes will affect the rural living environment

[0003] On the other hand, a sewage treatment system with high effluent quality usually includes multiple modules, all of which require on-site construction. The cost is too high, the structure is complex, and the construction period is long, so it is not suitable for rural areas.
