Efficient ecological purification system for domestic sewage treatment

Abstract

The invention belongs to the technical field of domestic sewage treatment, and particularly relates to an efficient ecological purification system for domestic sewage treatment. The efficient ecological purification system comprises a first-stage purification system, a second-stage purification system and a third-stage purification system which are communicated in sequence, wherein the first-stage purification system is communicated with an external water inlet pipe, the third-stage purification system is communicated with an external water drainage pipe, the first-stage purification system consists of a first-stage purification pond, emergent aquatic plants A and floating-leaved plants A which are planted in the first-stage purification pond, and mollusks A and fishes A which are cultured in the first-stage purification pond, the second-stage purification system is composed of a second-stage purification pond, emergent aquatic plants B and floating-leaved plants B which are planted in the second-stage purification pond, and mollusks B cultured in the second-stage purification pond, and the third-stage purification system is composed of a third-stage purification pond and a biological system planted in the third-stage purification pond. The ecological treatment system can effectively treat domestic sewage and has important environmental value and social value.

Description

technical field [0001] The invention belongs to the technical field of domestic sewage treatment, and in particular relates to an efficient ecological purification system for domestic sewage treatment. Background technique [0002] With the rapid development of society and the continuous improvement of people's living standards, the discharge of industrial sewage and domestic sewage has surged, and unreasonable discharges have occurred. Excessive nitrogen, phosphorus and other nutrients have entered natural water bodies, exceeding the self-purification capacity of rivers and lakes, resulting in Water bodies such as vast rivers and lakes are polluted, which in turn causes eutrophication of water bodies. Especially in some remote areas or concentrated resettlement areas, such as villages and towns, the infrastructure construction is not perfect, the pipe network is not complete, and the pollution points of villages and towns are scattered, domestic sewage cannot be collected a...

AI Technical Summary

Problems solved by technology

[0003] Traditional treatment systems, such as the construction or improvement of sewage collection pipe networks, and centralized collection and treatment of sewage, can solve the problem of direct sewage discharge, but this method is costly, and the cost of later operation and maintenance is high, so it can only be applied to cities and towns with complete supporting facilities And industrial parks, etc., for these scattered areas without supporting pipe network, the system is not practical
