The right combination and sequence of treatment methods is the key to the successful handling of rural domestic sewage. This research aim was to carry out experimental study on the combined process and assess its efficiency, feasibility, robustness and suitability for rural domestic sewage treatment and explore the best treatment effect and operating parameters. The parameter optimized and controlled includes hydraulic retention time (HRT) and temperature during the entire research operations. The average COD, TN, NH4+-N and TP removal efficiency of the combined process was 78.2%, 70%, 76% and 87% respectively. Overall, the combined process proved to be efficient and suitable for rural domestic sewage treatment.
