摘　　要：长期滥用抗生素导致细菌耐药性增强,并使抗性广泛传播.污水处理厂既是耐药菌(antibiotic resistance bacteria,ARB)与抗性基因(antibiotic resistance gene,ARG)的储存库,排放的污水与污泥是向自然环境中传播抗性的重要污染源,也是削减ARB和ARG及控制抗性传播的重要环节.本文总结了天然水体中的耐药菌和抗性基因污染现状,分析了近年来耐药菌与抗性基因在污水/污泥处理过程中的转归与去除方面的研究进展,同时对将来的重点研究方向提出展望,以期为今后耐药菌和抗性基因的污染控制提供参考.The abuse and overuse of antibiotics lead to increasing bacterial resistance to actibiotics and extensive dissemination of resistance. As a reservoir for antibiotic resistance bacteria （ARB） and antibiotic resistance gene （ARG） , the effluent and biosolids of wastewater treatment plants （WWTPs） are the important contamination sources for the antibiotic resistance dissemination. Meanwhile, WWTPs play an important role in controlling of resistance dissemination. The purpose of this paper is to summarize pollution status of antibiotic resistance in the aquatic environment, to thoroughly review the advances of removing ARB and ARG during WWTP treating processes, and to propose the future research direction.
