摘　　要：综述了芳香污染物、金属和金属纳米颗粒、抗生素等3种污水中常见微量污染物对厌氧氨氧化(Anammox)菌群的抑制效应,分析了导致Anammox活性丧失的抑制机理,指出抑制作用多表现为对细胞膜的损害,抑制效果受污染物在细胞质中扩散、溶解和摄入细胞能力的影响。针对不同的污染物提出了相应的应对策略,可以通过淘洗菌种、投加新鲜种群、添加促进剂等方式提高Anammox活性和胞外聚合物(EPS)含量,也可以利用驯化手段诱导抗性基因的产生,或采用生物膜法增强Anammox群落对污染物的耐受性。This review summarized the inhibitory effects of three common trace pollutants in sewage,namely aromatic pollutants,metals and metal nanoparticles,and antibiotics,on Anammox bacterial community,and analyzed the inhibitory mechanism leading to the loss of Anammox activity.It pointed out that the inhibitory effects was mainly the damage to the cell membrane,and the inhibitory effect was influenced by the ability of pollutants to diffuse,dissolve and ingest cells in the cytoplasm.Corresponding response strategies were proposed for different pollutants,such as increasing Anammox activity and extracellular polymeric substance(EPS)content by washing the bacterial strains,introducing fresh populations and adding enhancers,and inducing the production of resistance genes by domestication,or using biofilm method to enhance the tolerance of Anammox community to pollutants.
