摘要
近年来由于抗生素滥用而导致的水污染日益严重,抗生素残留及耐药性已成为当今社会面临的最严峻挑战之一。高级氧化工艺以其快速的反应速率和良好的处理效果,越来越多地被用于治理含抗生素的废水。本文首先阐述了抗生素的污染现状;其后根据起主导作用的自由基种类,分类对比了传统高级氧化和过硫酸盐高级氧化处理抗生素及耐药性的特征,深入分析了过硫酸盐高级氧化的反应机理,重点介绍了热活化、紫外活化、零价铁及其改性活化和电活化等不同活化过硫酸盐的方式,并研究总结了这些技术用于处理抗生素及其耐药性的降解效果和进展;综合分析了目前高级氧化降解抗生素及去除耐药性的环境影响因素和存在的问题;最后对高级氧化的未来发展进行了展望。
In recent years,the water pollution caused by the abuse of antibiotics has become increasingly serious,so antibiotics residue and antibiotic resistance have become one of the most serious challenges today.With fast reaction rate and good treatment effect,advanced oxidation processes are increasingly used to treat wastewater containing antibiotics.This article firstly describes the current status of antibiotic pollution.Moreover,according to the classification of free radicals,the characteristics of antibiotics and antibiotic resistance bytraditional and persulfate advanced oxidation treatments were compared.Later,the basic characteristics and reaction mechanism of persulfate advanced oxidation were analyzed in depth.Meanwhile,the degradation effects and research progress of different activation methods for antibiotics and antibiotic resistance were reviewed and summarized,mainly focusing on thermal,ultraviolet,transition metal,and electrical activation,and the environmental impact factors and existing problems of advanced oxidation degradation of antibiotics and antibiotic resistance removal were comprehensively analyzed.Finally,the future development of advanced oxidation was prospected.
