Abstract

The invention provides a detachable constructed wetland-based domestic sewage treatment system. The detachable constructed wetland-based domestic sewage treatment system comprises a water collecting tank and a body, wherein the body comprises a first cavity and a second cavity; the first cavity is connected with the second cavity through a detachable connecting component; the second cavity is communicated with the water collecting tank; a plurality of supporting nets are arranged inside the first cavity and the second cavity; the first cavity is sequentially filled with a soil layer with a vegetation area, a zeolite layer and a limestone layer from top to bottom; the second cavity is sequentially filled with a soil layer, a wheat husk layer or a wood chip layer, a quartz sand layer and a ceramsite layer from top to bottom. Through the simulation of a variety of biological, chemical and physical properties and the like of a matrix, soil, plants and microorganisms in a constructed wetland, various pollutants in sewage and sludge are comprehensively adsorbed, absorbed and purified, so that the purpose of safe discharge is achieved. The detachable constructed wetland-based domestic sewage treatment system is miniaturized and modularized, the dredging convenience thereof is improved, and the sewage treatment efficiency of the wetland is not affected while the convenience is ensured.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment, in particular to a detachable artificial wetland domestic sewage treatment system. Background technique

[0002] Constructed wetland is a kind of artificially constructed comprehensive ecosystem similar to natural wetland. Constructed wetland system gives full play to the advantages of biological coexistence, material recycling and resource recycling in the ecosystem, greatly reduces the cost of pollution control, and realizes The purification of sewage prevents the spread and impact of pollutants to obtain the best benefits of sewage treatment. The convenience and operability of constructed wetlands play an important role in practical applications. It helps to remove pollutants in the matrix, and is also conducive to expanding the application range of wetlands and increasing their feasibility. Most of the existing constructed wetlands are relatively large-scale wetlands, the operation ...
