[email protected] Abstract. In recent years, measures have been taken against rural environmental problems, and remarkable achievements have been made in the construction of sewage treatment facilities, but there are still some problems. This paper takes three small sewage treatment facilities in the hilly areas of Sichuan as the research object, through field research and data collection, statistical analysis and analysis of various facilities, combined with actual use, the corresponding optimization development proposals are summed up to optimize the utilization efficiency of the facilities and improve the living environment in the rural areas. The results show that the combination of A2O+MBBR is more suitable for the economy and performance at Sichuan hilly areas, but other options can be selected according to different situations to achieve the best results.
