Problems solved by technology

[0004] The invention solves the problem that the existing centralized sewage treatment mode is difficult to carry out in rural areas where residents live relatively scattered, and provides a sewage treatment device and method. The grid filter, artificial wetland and photocatalytic reaction tank make the pollutants in the sewage pass through the multi-stage treatment unit, and finally collect them into the sump for reuse, which improves the efficiency and effect of purification
The devices provided by the invention all adopt physical methods, do not involve the addition of any chemical reagents, can be controlled automatically or manually, and can be used at any time for the problem of large fluctuations in the amount of sewage in rural areas. source purification

Abstract

The invention provides a sewage treatment device and method. The device comprises an anaerobic tank for performing anaerobic treatment on black water, a filter tank for filtering sewage subjected to anaerobic treatment, a degradation tank for performing nitrogen and phosphorus degradation on the filtered sewage, a photocatalytic reaction tank for oxidizing ammonia nitrogen in the degraded sewage, and a collection tank for collecting water subjected to photocatalysis, wherein the anaerobic tank, the filter tank, the degradation tank, the photocatalytic reaction tank and the collection tank are sequentially communicated through pipelines arranged at the bottoms of the anaerobic tank, the filter tank, the degradation tank, the photocatalytic reaction tank and the collection tank. According to the reasonably-coupled whole set of sewage treatment system, pollutants in sewage can be simply and efficiently degraded, the problem that centralized treatment cannot be performed due to dispersion of rural sewage and large fluctuation of water quality and water quantity is solved, the rural sewage is treated from the source, and potential hazards caused by flowing of the rural sewage in ditches are reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device and method suitable for rural environment treatment. Background technique [0002] The discharge of domestic sewage in rural areas is an important factor causing water environment pollution. Strengthening the collection, treatment and resource utilization of rural domestic sewage is an urgent problem to be solved in improving the rural water environment, and it is also an important part of the rural revitalization strategy. However, due to the serious shortage of coverage of rural sewage treatment facilities in my country, the problem of rural domestic sewage has become an important factor affecting the living environment and ecological environment in rural areas. From the perspective of treatment methods, my country's rural sewage treatment mainly includes three methods: decentralized treatment, township centralized treatment and municipal uni...
