摘要
近年来,随着生活水平的提高,我国药品生产和使用量急剧增加;同时个人护理产品的消费量也在快速增长,由此引发水环境中持续存在药物和个人护理产品等新污染物,其中抗生素类药物污染尤为突出。目前,基于过硫酸盐的高级氧化法,因其具有反应时间短、降解效率高、适用范围广等优点,被视为一种具有应用前景的水净化技术。本综述首先详细介绍国内抗生素的使用和污染现状,剖析抗生素的来源和迁移过程,其次系统阐述过硫酸盐的活化体系(热活化、辐射活化、超声活化、金属/非金属催化剂非均相活化等),再次深入探讨过硫酸盐高级氧化技术对抗生素的降解机理(自由基和非自由基机制),最后对该技术仍存在的问题进行了分析,对未来研究方向进行了展望。本文以期为活化过硫酸盐高级氧化技术在降解抗生素的实际应用中提供一定的参考。
In recent years,with the improvement of living standards,the production and use of pharmaceutical increased sharply in our country,and pharmaceutical and personal care products(PPCPs)is also growing rapidly,which leads to the continuous existence of emerging contaminants such as pharmaceuticals and PPCPs in the water environment,with antibiotic pharmaceutical contamination being particularly prominent.At present,advanced oxidation technology of persulfate is regarded as a promising water purification technology due to its advantages such as short reaction time,high degradation efficiency and wide application range.This review firstly introduces the use and pollution status of antibiotics in China,and analyzes the source and migration process of antibiotics,then systematically expounds the activation system of persulfate(heat activation,radiation activation,ultrasonic activation and heterogeneous activation of metal/non-metallic catalysts),and discusses the degradation mechanism of advanced oxidation technology of persulfate on antibiotics(radical and non-radical mechanisms).Finally,the existing problems of this research direction are analyzed,and the future development direction is prospected.This review is expected to provide useful information for the practical application of persulfate advanced oxidation process in the degradation of antibiotics.
