Abstract

The invention discloses a domestic sewage treating and recycling device and belongs to a sewage treatment device. The domestic sewage treating and recycling device comprises a water inlet pipeline and a first water outlet pipeline, wherein the water inlet pipeline is communicated with a first gravel column through a first pipeline; the first gravel column is communicated with a second gravel column by a second pipeline; the second gravel column is communicated with the first water outlet pipeline by a third pipeline; the first pipeline is also communicated with a solid residue channel; the solid residue channel is also provided with an interdicting device used for controlling on and off of the solid residue channel; and the second pipeline is also communicated with a second water outlet pipeline. Domestic sewage is filtered by a filter, the first gravel column and the second gravel column circularly, the sewage can be treated at different degrees according to different requirements of domestic water and irrigation, and the domestic sewage treating and recycling device provided by the invention is simple in structure, good in water quality, great in concentration ratio, low in cost, low in energy consumption and has multiple purposes, short flow, fast speed and wide application prospect.

Description

technical field [0001] The invention relates to a sewage treatment device, more specifically, the invention mainly relates to a domestic sewage treatment and recycling device. Background technique [0002] Agricultural non-point source pollution is the most important type of non-point source pollution. It mainly refers to various pollutants produced in agricultural production activities. Pollution caused by pollutants entering water bodies. Rural domestic sewage is one of the most important sources of agricultural non-point source pollution. The main components of rural domestic sewage include nitrogen, phosphorus, organic matter, LAS, pathogenic bacteria, etc. Some of these substances, such as nitrogen and phosphorus, are beneficial nutrients for plants and can provide important nutrients for plant growth. Organic matter can improve soil fertility and productivity levels . However, excess nutrients, organic matter, and some other substances may have an impact on the soil...
