In recent years, with the degree of urban-rural integration, the economic level of rural areas and the improvement of residents’ health awareness, the water quality pollution of rural domestic sewage has increased year by year, and the problem of rural sewage discharge has become increasingly prominent. In order to improve the rural water environment and solve the problem of random discharge of sewage, this paper takes the rural domestic sewage as the research object, and takes the natural sedimentation and anaerobic fermentation as the main means to study the on-site resource utilization technology of sewage. It was found that after 3 hours of sewage sedimentation, organic suspended solids settled naturally, resulting in a significant decrease of COD in the upper sewage to 93.29 mg/L. Because of the special bimolecular structure of LAS, the concentration of LAS in surface sewage increased sharply to 7.68mg/L, but it was lower than 10mg/L, which met the irrigation water standard.
