摘　　要：超滤工艺被广泛应用于城镇污水厂二级出水的深度处理,其膜污染问题是阻碍水回用系统经济、稳定运行的重要因素。当前突发环境事件频发,已对污水厂深度处理的稳定性构成严重威胁。综述了二级出水有机物特征对超滤膜污染的影响,总结了典型环境突发事件对污水处理系统中微生物代谢和群落结构的影响,在此基础上对典型突发事件影响下二级出水超滤膜污染的未来研究方向提出了建议,旨在降低未来突发环境事件对污水厂运行的负面影响。Ultrafiltration is widely applied as an advanced treatment process to treat the secondary effluent of municipal wastewater.However,membrane fouling has long been an important factor influencing the economy and stability of the water reuse system.Currently,high frequent occurrence of environmental emergencies poses huge threats to the advanced treatment of sewage plants.Characteristics of effluent organic matter and their influence on ultrafiltration membrane fouling were reviewed.The effects of environmental emergencies on microbial metabolism and microbial community structure in wastewater treatment systems were summarized.Based on this information,the research directions of mechanism and control of ultrafiltration membrane fouling under the influence of environmental emergencies were recommended.It is hoped to reduce the negative impacts of future environmental emergencies on the operation of wastewater treatment plants.
