The extensive use of tetracycline-series antibiotics in the breeding and medical industries has caused continuous selection pressure on bacteria,resulting in the wide distribution of tetracycline resistance genes(TRGs)in the environment.A variety of TRGs are classified as Class Ⅰ environmental risk,posing a serious threat to human health and ecological security.Waste water Treatment Plants(WWTPs)are an important reservoir for TRGs and an important pathway to eliminate resistance genes.The occurrence characteristics of TRGs in WWTPs are summarized,conventional treatment techniques are compared and analyzed,and novel advanced treatment techniques are mainly explored,aiming to provide a reference for further effective removal of TRGs and comprehensive prevention and control of antibiotics resistance genes contamination.
