摘　　要：以温度为主要特征参数,采用实验室模拟方法,研究A/O-MBR联合人工湿地系统处理农村污水的效果,一个处理周期内,温度分别设置9℃、13℃、18℃、23℃、30℃,探究系统对COD、总氮、总磷的处理效果。结果显示:温度会影响A/O-MBR联合人工湿地系统处理农村生活污水的效果,A/O-MBR系统随温度升高对COD的处理效率提升,对TP和TN的处理效率下降;A/O-MBR联合人工湿地系统对COD、TN、TP的处理效率均随温度升高而略有升高。Taking temperature as the main characteristic parameter, laboratory simulation methods were used to study the effect of A/O-MBR combined with constructed wetland system in treating rural sewage, and the temperature was set to 9 ℃, 13 ℃, 18 ℃, 23 ℃ and 30 ℃ respectively in one treatment cycle, and the treatment effect of the system on COD,total nitrogen and total phosphorus was explored. The results showed that the temperature would affect the effect of A/OMBR combined with constructed wetland system in treating rural domestic sewage, and the treatment efficiency of COD and TP and TN decreased by A/O-MBR system with the increase of temperature. The treatment efficiency of A/O-MBR combined with constructed wetland system for COD, TN and TP increased slightly with the increase of temperature.
