摘要

       抗生素抗性基因 (ARG) 已被视为当今关注的新兴污染物。没有专门的技术可以直接去除废水处理厂 (WWTP) 中的 ARG。为了降低 ARGs 的风险，了解先进处理技术在去除污水处理厂中抗生素抗性基因方面的效率至关重要。本综述基于对污水处理厂中 ARGs 的发生和归宿的了解，重点介绍了三级处理技术在消除 ARGs 方面的应用和效率。这些技术包括化学工艺，如氯化、臭氧、紫外线和高级氧化技术，以及物理分离工艺、人工湿地和膜生物反应器等生物工艺，以及土壤含水层处理。讨论了这些过程的优点、局限性和改进措施，以优化未来的治疗策略并确定新的研究方向。

       Antibiotic resistance genes (ARGs) have been considered as emerging contaminants of concern nowadays. There are no special technologies designed to directly remove ARGs in wastewater treatment plants (WWTPs). In order to reduce the risk of ARGs, it is vital to understand the efficiency of advanced treatment technologies in removing antibiotic resistance genes in WWTPs. This review highlights the application and efficiency of tertiary treatment technologies on the elimination of ARGs, s, based on an understanding of their occurrence and fate in WWTPs. These technologies include chemical-based processes such as chlorination, ozonation, ultraviolet, and advanced oxidation technology, as well as physical separation processes, biological processes such as constructed wetland and membrane bioreactor, and soil aquifer treatment. The merits, limitations and ameliorative measures of these processes are discussed, with the view to optimizing future treatment strategies and identifying new research directions.
