摘　　要：以水解调节池为A段、一体化生物转盘为O段组成A/O工艺处理生活污水,在回流比为300%左右、水温15~25℃、HRT为11 h时,COD、氨氮、TN的去除率分别能达到85%、90%和60%,出水水质满足《农村生活污水处理设施水污染物排放标准》一级A排放标准。水温降低至10℃以下,COD的去除出现小幅下降,氨氮的去除效率大幅降低,TN的去除稳定在10%左右。A/O process is composed of hydrolysis regulating tank as section A and integrated biological rotary table as section o to treat domestic sewage.When the reflux ratio is about 300%,the water temperature is 15~25℃and HRT is 11h,the removal rates of COD,ammonia nitrogen and TN can reach 85%,90%and 60%respectively.The effluent quality meets the class a discharge standard of the discharge standard of water pollutants for rural domestic sewage treatment facilities.When the water temperature drops below 10℃,the removal of COD decreases slightly,the removal efficiency of ammonia nitrogen decreases significantly,and the removal of TN is stable at about 10%.
