摘要

抗微生物耐药性（AMR）是现代社会面临的一个严重问题，不仅与临床环境有关，还与自然环境有关。常规废水处理厂（WWTP）是向水生环境传播抗生素耐药性的重要节点，因为它们是抗生素耐药性细菌（ARB）、抗生素耐药性基因（ARGs）和抗生素残留的宿主。污水处理厂并不是为了从废水中去除这些抗生素耐药性决定因素而设计的，因此，它们存在于处理过的废水中，导致了废水处理和再利用方面的环境和公共卫生问题。与传统WWTP相结合的额外治疗可能是AMR向环境传播的障碍。为了了解废水处理方法对去除ARB和ARGs的影响，进行了广泛的文献研究。本文综述了传统消毒方法、三级废水处理和高级氧化工艺（AOPs）去除废水中ARB和ARGs的效率。在修订后的《城市污水处理指令91/271/EEC》中，需要对AOP的去除潜力进行全面的进一步研究，因为与传统消毒方法相比，AOP在去除ARB和ARG方面具有巨大潜力，且有毒副产物的形成量较低。

The Fate and Occurrence of Antibiotic-Resistant Bacteria and Antibiotic Resistance Genes during Advanced Wastewater Treatment and Disinfection: A Review

Antimicrobial resistance (AMR) is a serious problem for modern society, not only associated with clinical environments, but also the natural environment. Conventional wastewater treatment plants (WWTPs) are important nodes for the dissemination of antibiotic resistance to the aquatic environment since they are reservoirs of antibiotic-resistant bacteria (ARB), antibiotic resistance genes (ARGs), and antibiotic residues. WWTPs are not designed to remove these antibiotic resistance determinants from wastewater, and as a result, they are present in treated effluent, leading to environmental and public health concerns regarding wastewater disposal and reuse. Additional treatments combined with conventional WWTPs can be barriers to the spread of AMR to the environment. In order to understand the effect of wastewater treatment methods on the removal of ARB and ARGs, an extensive bibliographic study was conducted. This review summarizes the efficiency of conventional disinfection methods, tertiary wastewater treatment, and advanced oxidation processes (AOPs) to remove ARB and ARGs from wastewater. In the context of the revised Urban Wastewater Treatment Directive 91/271/EEC, further studies are needed on the removal potential of AOPs on a full-scale, as they offer great potential for the removal of ARB and ARGs with a low formation of toxic by-products compared to conventional disinfection methods.

期刊介绍： Water (ISSN 2073-4441) is an international and cross-disciplinary scholarly journal covering all aspects of water including water science and technology, and the hydrology, ecology and management of water resources. It publishes regular research papers, critical reviews and short communications, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
