Biological purification tank for integrated treatment on excrement and sewage

Abstract

The invention discloses a biological purification tank for integrated treatment on excrement and sewage. The device comprises a vertical biological septic tank and a vertical biological purification tank, the vertical biological septic tank comprises a first outer tank body and a first inner tank body, the first inner tank body is located in the first outer tank body, the upper end of the first inner tank body is connected to the first outer tank body, a first flow guide seam is formed between the lower end of the first inner tank body and the first outer tank body, the vertical biological purification tank comprises a second outer tank body and a second inner tank body, a second flow guide seam is formed between the lower end of the second inner tank body and the second outer tank body, an aeration pipe is arranged above the inner wall of the bottom of the second outer tank body, a biological filler is arranged in the second inner tank body, comprehensive domestic sewage of farmers flows into the first inner tank body of the vertical biological septic tank and then is subjected to primary sedimentation, then the sewage goes through the first flow guide seam in the lower portion ofthe inner tank body and the lower portion of the outer tank body, enters the interlayer between the inner tank body and the outer tank body and is subjected to secondary sedimentation, so that the excrement and sewage separation effect is better, and then the sewage enters the second inner tank body and then undergoes a biochemical reaction.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a biological purification tank for the integrated treatment of feces and sewage. Background technique [0002] Farmer toilets in natural villages in China are generally unsanitary dry toilets, and daily sewage is discharged in an orderly manner, causing certain environmental pollution around the village. Promoting the rural "toilet revolution" is an important part of the implementation of the rural revitalization strategy and a key task of improving the living environment in rural areas. It is related to the most direct and practical interests of the peasants, and it is related to the realization of a comprehensive well-off in the countryside. Therefore, it is an urgent problem to solve the problem of toilet sanitation and domestic sewage treatment in a unified manner. [0003] There is an invention patent with the application number 201820776210.3, which disc...

AI Technical Summary

Problems solved by technology

[0004] However, there are the following problems in the comparison documents and the existing vertical purification tanks. 1. The sedimentation and separation effect of feces is poor, and at the same time it is short in the height direction, and the feces need to be separated by gravity. Due to the short distance in the vertical direction, It also leads to poor sedimentation and separation effect. 2. It is inconvenient to clean the sedimented manure, which increases the difficulty of cleaning. 3. It occupies a large area and has poor practicability.
