Description

A rural domestic sewage recycling system

Technical Field

The invention relates to the technical field of domestic sewage recycling, and in particular to a rural domestic sewage recycling system.

Background Art

Rural domestic sewage treatment is to remove harmful substances and environmental pollutants in domestic sewage, degrade them and treat them harmlessly. Rural domestic sewage treatment should focus on the selection of mature and reliable technologies that are suitable for rural characteristics and actual sewage treatment. Rural sewage treatment can neutralize water quality and agricultural products according to actual conditions, so as to achieve the purpose of environmental protection and recycling.

After searching, the public (announcement) number is: CN214019523U. A rural domestic sewage comprehensive utilization system can double-treat the sewage generated in rural areas, treating the sewage into purified water and fertilizer, wherein the purified water is used to irrigate farmland, and the fertilizer is used to fertilize crops; in addition, the sewage treatment device uses a filter membrane to filter the sewage to form raw water and raw sludge, wherein the raw water must be purified before it can be used to irrigate crops. Among them, the filter membrane adopts an inclined shape, which increases the contact area between the sewage and the filter membrane, thereby improving the efficiency of sewage-water separation.

Although the existing sewage recycling system can filter and treat sewage, the filtered impurities cannot be effectively treated and will still cause environmental pollution.
