A combined processes facility of “oil separation, anaerobic tanks, A2O integrated equipment and subsurface constructed wetland” has been adopted for rural sewage treatment. The facility operates stably with a good water purification effect. During the monitoring period, the average removal rates of SS, COD, NH3-N, TN and TP by the combined process facility are 94.7%, 92.9%, 70.5%, 64.8% and 84.7%, respectively. The A2O integrated equipment has the largest contribution rate to the removal of SS, COD, NH3-N and TN, while the constructed wetland contributes the most to the removal of TP. Except for SS, the removal of pollutants is affected by seasonal changes, with a better removal effect in summer than in winter. The monitoring results show that the combined process facility is characterized with a good pollutant removal capacity and a high shock load resistance efficiency, which makes it suitable for popularization and application in rural areas.
