摘　　要：四环素类抗生素(TCs)的广泛应用导致其在水体及土壤环境中大量残留,严重破坏水体生态平衡,危害人体健康.近年来,基于硫酸根自由基的活化过硫酸盐高级氧化技术具有效率高、速度快、反应彻底且作用条件温和等优点,已被广泛应用于处理废水中各类有机污染物的研究.本文综述了近几年来国内外利用紫外光、热、超声波、电活化、过渡金属、炭材料、负载金属催化剂活化以及联合活化技术在过一硫酸盐和过二硫酸盐氧化降解TCs中的研究与应用现状,并围绕催化剂的制备及特点、活化过硫酸盐的内在机制、自由基及非自由基产生途径、TCs的降解效果及降解途径等方面展开阐述.最后指出了该技术目前面临的问题及未来的发展方向,以期为过硫酸盐活化技术在抗生素废水处理中的进一步推广和应用提供参考.The extensive application of tetracycline antibiotics(TCs)leads to a large number of residues in water and soil environment,which seriously damages the ecological balance of water and harms human health.In recent years,activated persulfate advanced oxidation technology based on sulfate radicals has been widely used to treat various organic pollutants in wastewater due to its advantages of high efficiency,fast speed,thorough reaction and mild action conditions.In this paper,the research and application of ultraviolet,heat,ultrasound,electric activation,transition metal,carbon materials,supported metal catalyst activation and combined activation technologies in the oxidative degradation of TCs by peroxymonosulfate and peroxydisulfate were reviewed,and around the preparations and characteristics of catalyst,the intrinsic mechanism of activation persulfate,the generation pathways of free radical and non-free radical,the degradation effect and pathways of the TCs etc.In the end,the current problems and future development direction of this technology were pointed out,to provide a reference from further popularization and application of persulfate activation technology in antibiotic wastewater treatment.
