摘　　要：针对目前城市污水处理厂进水水质以生活污水为主转向以难生物处理的工业废水为主的现状,进行了A/O工艺的耐受性试验。结果表明随着工业废水比例的增加,厌氧、好氧污泥活性都显著下降,厌氧污泥的耐受性较高;随着运行时间的延长,两类污泥的活性逐步得到不同程度的恢复;工业废水比例越高,活性恢复所需时间越长;两类污泥的协同代谢作用保证了出水效果。A/O工艺所能耐受的进水中制药废水、印染废水和生活污水的分配比(体积比)为3∶3∶4。In this paper,the tolerance of anoxic/oxic process was studied with the consideration of the situations of wastewater quality from the historical domestic sewage histroly to the difficultly biodegradable realistic industrial wastewater in influent flowing into the municipal sewage treating plant. The results demonstrated that with increasing of rate of industrial wastewater in influent,the activities of anaerobic and aerobic sludge declined markedly and the tolerance of anaerobic sludge was higher. With the prolonging of the operation, the activities of anaerobic and aerobic sludge recovered gradually and the time for activity recovery was directly proportional to the ratio of industrial wastewater in influent. The removal rate of substrate was related with the cometabolism between anaerobic and aerobic bacteria. The tolerance value of A/O process treating the composite wastewater was 3 ： 3 ： 4 for the ratio of pharmacy producing wastewater,dyeing and printing wastewater and domestic sewage in influent.
