Rural domestic sewage treatment is the focus and difficulty of promoting the improvement of rural human settlement environment.

Compared with urban domestic sewage treatment, rural domestic sewage composition is simpler, and the treatment method is not as large as urban scale. However, due to the large differences in population aggregation degree, natural environment and economic and social development level between different regions, the collection rate and treatment rate of domestic sewage in some rural areas are generally low, and the existence of a large number of black and odorous water bodies has become a difficult problem restricting the improvement of rural human settlement environment.

Therefore, to improve the rural living environment, it is necessary to take measures according to local conditions, and the collection and treatment rate of rural domestic sewage should be increased. Village development planning, distance of urban pipe network, population size and aggregation degree, economic conditions, topography and other factors should be fully considered, and treatment methods such as integration into urban sewage pipe network and construction of centralized or decentralized treatment facilities should be adopted according to the situation. Unified collection and centralized treatment is one of the most economical and effective ways to treat domestic sewage.

Therefore, it is necessary to improve the long-term management and protection operation system of sewage treatment facilities. Shandong Holy Shield sewage treatment equipment serves many enterprises and institutions, and the treatment effect is good, and the effluent quality meets the discharge standards of relevant departments. The buried WSB type sewage treatment equipment is not only simpler and more intelligent to operate, but also more scientific and efficient in sewage treatment process. It mainly uses A/O/O biochemical process, integrates BOD5, COD, NH3-N and other processes in one, and can effectively treat general rural domestic sewage and industrial wastewater like domestic sewage.

This kind of buried sewage treatment equipment, its performance in sewage treatment, has been recognized by the State Environmental Protection Administration, has been regarded as sewage treatment benign equipment, widely adopted as the necessary facilities for local domestic sewage treatment.
