摘要
      抗生素耐药性基因是一种新出现的污染物,在不同的水生环境中经常被检测到,对公众健康和生态系统构成潜在风险。设计和操作得当的废水处理工艺可以成为减少排放到环境中的ARGs数量的有效最终屏障。为了控制抗微生物耐药性在环境中的传播,有必要全面了解各种废水处理过程对ARGs的消除和灭活。本文系统地总结和分析了ARGs在不同废水处理工艺中去除的可行性和效率,包括生物工艺,如膜生物反应器工艺和人工湿地;化学工艺,如臭氧氧化、氯化、芬顿氧化和其他高级氧化工艺(AOPs);物理化学过程,如紫外线辐射、电离辐射;以及物理过程,如凝结和膜过滤。此外,还讨论了这些处理工艺在消除和灭活废水中ARGs方面的优势和局限性以及未来的发展方向,旨在为未来的研究提供更好的理解和支持。
Abstract
Antibiotic resistance genes (ARGs) are emerging contaminants, which have been frequently detected in different aquatic environments, posing potential risk to public health and ecosystem. A properly designed and operated wastewater treatment process can be an effective final barrier for reducing the quantity of ARGs discharged into the environment. In order to control the propagation of antimicrobial resistance in the environment, it is essential to comprehensively understand the elimination and inactivation of ARGs by various wastewater treatment processes. This review systematically summarized and analyzed the feasibility and efficiency of ARGs removal in different wastewater treatment processes, including biological processes, such as membrane bioreactor process and constructed wetlands; chemical processes, such as ozonation, chlorination, Fenton oxidation and other advanced oxidation processes (AOPs); physicochemical processes, such as UV radiation, ionizing radiation; and physical processes, such as coagulation and membrane filtration. In addition, the advantages and limitations as well as future direction of these treatment processes for the elimination and inactivation of ARGs in wastewater were also discussed, aiming to provide better understanding and support for future research.
