摘　　要：根据当前抗生素研究领域的最新文献报道,污水脱氮除磷系统通常无法完全去除四环素,四环素是污水处理厂最频繁、广泛检出的抗生素之一。四环素长期存在于水体中会引起环境风险,威胁人类健康。根据当前抗生素研究领域的最新文献报道,对四环素在水环境中的迁移转化,四环素对污水生物脱氮除磷过程的影响以及相关机理最新研究情况进行了综述,并对今后的研究方向进行了展望。According to the latest literature reports in the field of antibiotic research,tetracycline is one of the most frequently and widely detected antibiotics in sewage treatment plants.Existing sewage treatment processes usually cannot completely remove tetracycline.Long-term presence of tetracycline in water can cause environmental risks and threaten human health.According to the latest literature reports in the field of antibiotic research,the migration and transformation of tetracycline in water environment,the generation of tetracycline-resistant microorganisms and resistance genes,and the effects of tetracycline on activated sludge structure and microbial community are reviewed.And the research direction is prospected.
