Rural domestic sewage resource classification efficient treatment system

Abstract

The invention relates to a rural domestic sewage resource classification efficient treatment system, and belongs to the technical field of sewage treatment. The system comprises a black water treatment tank, a domestic sewage first-stage treatment tank, a domestic sewage second-stage treatment tank and a domestic sewage third-stage treatment tank, wherein the black water treatment tank comprises ablack water deodorization tank, an anaerobic treatment tank, a composting tank, a liquid fertilizer tank and a urine tank. According to the system, domestic black water is intensively collected intothe black water deodorization tank through a black water collection pipeline; after being deodorized in the black water deodorization tank, the black water flows into the anaerobic treatment tank, andis subjected to a reaction to generate methane and black water, the methane is collected and utilized by a methane power generation device, and the black water enters the composting tank or the liquid fertilizer tank; and the black water in the urine tank and grey water are mixed and pass through the domestic sewage first-stage treatment tank, the domestic sewage second-stage treatment tank and the domestic sewage third-stage treatment tank so as to be purified. According to the invention, the method mainly solves the problem that rural domestic sewage is randomly discharged to pollute the environment, and has important effects in the improvement of rural ecological environments, the improvement of living quality of farmers, the increasing of resource utilization rate of domestic sewage,and the like.

Description

technical field [0001] The invention relates to a classification and high-efficiency treatment system for resource utilization of rural domestic sewage, which belongs to the technical field of sewage treatment. Background technique [0002] In recent years, with the rapid development of the rural economy, the living standards of farmers have been continuously improved, but the construction of its infrastructure has not been matched with the rapid economic development in the countryside. Under the background of the rapid development of the rural economy, what is hidden is the imperfection of infrastructure construction, which has caused a series of problems, among which the problem of water environment pollution is particularly serious. Rural domestic sewage treatment is an important part of the improvement of rural human settlements and an important measure to implement the strategy of rural revitalization. However, at present, rural domestic sewage treatment is still the m...

Problems solved by technology

However, although the patent published by the patent number CN201610337806.9 has a simple structure and is suitable for rural areas, it can realize the graded treatment and utilization of domestic sewage, but considering that it can only absorb solid impurities in domestic sewage, it is harmful to nutrients, organic matter, bacteria and viruses. There are no effective solutions, and it cannot alleviate the problem of non-point source pollution caused by the random discharge of rural domestic sewage

[0004] At present, the problem of domestic sewage treatment in rural areas has not been effectively solved. The main problem is that a suitable method for domestic sewage treatment in rural areas has not been found.
