高级氧化技术降解水体中抗生素的研究进展

抗生素是一类用于阻止和治疗微生物传染性疾病的人用和兽用药物,在人类和动物疾病治疗领域以及水产养殖业有着广泛的用途。近年来,抗生素作为一种新型污染物不断排入水体并且在水体中持续存在,对水生态环境以及人类健康造成了威胁。化学和生物等降解技术引起广泛关注,其中高级氧化技术(AOPs)由于其具有适用范围广、反应速率快、氧化能力强等特点,被成功应用到自然水体和污水中抗生素等多种有机污染物的降解。基于近年来的研究成果,综述了几种常见AOPs对抗生素的降解过程和机理,对比分析了对抗生素的降解效果,最后展望了AOPs应用于抗生素降解的研究方向和挑战。

Research Progress on Degradation of Antibiotics Via Advanced Oxidation Processes

Antibiotics,used in human and veterinary medicine,as well as in aquaculture,for the purpose of preventing or treating microbial infections,have been considered emerging pollutants due to their continuous input and persistence in the aquatic ecosystem,had posed a threat to ecological environment and human health over past few years.Many investigations on chemical and biological technologies have been reported for the decomposition of antibiotics in aqueous matrices during past years.Among them,the advanced oxidation processes （AOPs） have been successfully applied in degradation of antibiotics and other organic pollutants in water and wastewater for their characteristics of wide application,high reaction rate and strong oxidation ability.Based on recent research,degradation processes and mechanisms of several common AOPs on antibiotics were summarized,the degradation effect was compared and research prospects and challenges were also outlooked.
