摘要
抗性基因(ARGs)污染已被联合国卫生组织列为21世纪新型三大污染问题之一,具备种类多样、转移方式灵活、污染风险存在极大的不确定性等特点.通过相应技术措施削减水体中的抗性基因污染,具有突出的现实意义.高级氧化技术(AOPs)降解效率高、条件可控、可操作性强,在水体深度处理上展现了良好的优势.本文综述了基于高级氧化技术的抗性基因污染治理方法研究进展,讨论了不同高级氧化技术(类Fenton氧化、光催化氧化、过硫酸盐氧化以及臭氧氧化)对抗性基因去除的影响,同时以此为背景展望了处理抗性基因污染的未来可研究方向.
Antibiotic resistant gene(ARGs) pollution has been listed as one of the three latest pollution problems in the 21 st century by the United Nations health organization, which has the characteristics of diversity, flexible transformation mode, and great uncertainty of pollution risk. It is of great practical significance to reduce the resistance gene pollution in water by employing relevant technical measures. Advanced oxidation progress technology(AOPs) has the advantages of high efficiency, controllable preparation conditions and strong operability, which have shown good performance in the advanced treatment of water body. This paper briefly reviewed the research progress of resistance gene pollution control methods based on AOPs technologies, and the influence of different AOPs technologies(Fenton-like oxidation, photocatalytic oxidation, persulfate oxidation and ozone oxidation) on ARGs elimination was discussed. Simultaneously, based on this background, the future research direction of ARGs gene pollution treatment was prospected.
