摘　　要：介绍了氯苯类化合物的结构、性质、污染现状。在对催化臭氧技术降解氯苯类化合物效能评述的基础上,针对催化臭氧机理研究的难点进行了分析,重点讨论了催化臭氧产生羟基自由基(·OH)的机理、降解氯苯类化合物的作用、影响因素等,最后讨论了该技术的研究方向。Structure, properties and present situation of pollution of chlorobenzenes were introduced. The degradation efficiency of chlorobenzenes（CBs） by the catalytic ozonation was reviewed. The reaction mechanism of the catalytic ozonation was discussed. And more attention was focused on the discussion of the generated mechanism of hydroxyl radicals（.OH） , the degradation mechanism and influencing factors of chlorobenzenes（CBs） that may exist in the catalytic ozonation process. At last the research direction of the catalytic ozonation was discussioned.
