摘　　要：对于废水中有毒有机污染物的降解,高级氧化工艺(AOPs)因其反应速率快、氧化能力强而受到越来越多的关注。在AOPs中使用催化剂会改善臭氧的分解,从而产生高活性的自由基,进而促进有机物快速、有效地矿化和降解。由于这些优点,催化臭氧氧化已经获得了普及。然而,均相催化臭氧氧化通过添加金属离子催化臭氧降解污染物,会产生二次污染物。非均相催化臭氧氧化利用金属、金属氧化物和碳材料作为固体催化剂来克服这一缺点。文中综述了催化臭氧氧化的分类、催化剂类型和影响因素,对催化臭氧氧化在抗生素污染物现状进行了分析和总结,给出了结论性意见,并讨论了其未来的前景和挑战。For the degradation of toxic organic pollutants in wastewater,advanced oxidation processes(AOPs)have attracted more and more attention because of its fast reaction rate and strong oxidation ability.The use of catalysts in AOPs can improve the decomposition of ozone,resulting in the generation of highly active free radicals,which in turn promote the rapid and effective mineralization and degradation of organic matter.Advanced catalytic ozonation has gained popularity because of these merits.However,homogeneous catalytic ozonation has the disadvantage of producing secondary contaminants from the addition of metallic ions.Heterogeneous catalytic ozonation can overcome this drawback by utilizing metals,metallic oxides,and carbon materials as a catalyst of efficacy and stability.This review discusses the classification,catalyst types and influencing factors of catalytic ozonation in antibiotic pollutants wastewater,and prospects in advancing the techniques in heterogeneous catalytic ozonation.
