摘　　要：纳米材料的生态效应已经引起人们的广泛关注,其中污水处理厂作为纳米材料重要的聚集地,其生态效应研究却刚刚起步。已有研究表明纳米材料会对活性污泥中微生物量、群落结构及功能基因等产生一定的影响,从而降低了污水处理的性能。该文综述了纳米材料对污水处理厂处理效能的影响及其潜在的毒性机制,并对该领域未来的发展方向进行展望。Ecological effects of nanomaterials have attracted extensive attention. However, the research of nanomaterials ecological effects on wastewater treatment plants （WWTPs）, the important receptors of nanomaterials, is just beginning. Studies have shown that nanomaterials can affect the biomass, microbial community structures and functional genes of activated sludge systems, which will result in the decrease of wastewater treatment efficiency. In this paper, the effects of nanomaterials on the WWTPs treatment process and the probable toxic mechanisms are summarized, the future research direction is prospected as well.
