| 中文摘要: |
| 由抗生素的不合理使用产生的抗生素抗性菌（Antibiotic-resistant bacteria，ARB）和抗性基因（Antibiotic resistance genes，ARGs）已广泛存在于各种环境介质中，对人类健康和生态安全造成了潜在危害。即使抗生素消减后ARB也能在环境中长期存在，ARGs可通过水平基因转移（Horizontal gene transfer，HGT）进一步扩散。污水处理厂是ARB和ARGs的储存库，也是实现其削减的重要环节。因此，探索可高效去除ARB和ARGs的污水深度处理工艺是十分必要的。本文综述了多种深度处理工艺对ARB和ARGs的去除研究进展，分析了氯消毒、紫外和臭氧氧化等传统消毒处理工艺和光/H2O2、光芬顿、光催化等高级氧化技术，以及人工湿地、混凝、膜处理等工艺对ARB和ARGs的去除效果与机理。在此基础上，对今后ARB和ARGs去除相关的研究重点和方向提出建议，以期为我国污水深度处理工艺的选择提供借鉴。 |
| 英文摘要: |
| Antibiotic-resistant bacteria (ARB) and antibiotic-resistance genes (ARGs), promoted by the improper use of antibiotics, have been frequently detected in various aquatic environments. They have caused potential hazard to both human health and ecological security. Antibiotic resistance exists for quite a long time, even in the absence of antibiotics, and ARGs can be further disseminated through horizontal gene transfer (HGT). Wastewater treatment plants (WWTPs) are a reservoir of ARB and ARGs and play an important part in their elimination. As a result, it is of great importance and necessity to explore an efficient advanced treatment process to remove ARB and ARGs properly. The aim of this review is to provide the current knowledge regarding inactivation of ARB and ARGs, with different advanced treatment processes in the effluent of WWTPs (chlorination, UV irradiation, ozonation, photo/H2O2, photo Fenton, and photocatalytic oxidation). The inactivation effects on ARB and ARGs with constructed wetlands, coagulation, and membrane treatment were also summarized. Finally, advice and suggestions were proposed for the future research direction:(1) The efficiency and mechanism of integrated processes on the removal of ARB and ARGs should be explored; (2) The behavior of various mobile genetic elements (MGEs) and their correlations with ARGs during the different advanced treatment processes should be further studied; (3) The scope of mechanism research should be extended to reverse transcription of ARB; and (4) More effective quantitative determination of ARGs should be exploited, as real-time fluorescence quantitative PCR may underestimate the removal efficiency of ARGs by advanced treatment processes. |
