摘　　要：介绍了药品及个人护理品中的广谱抗菌消毒剂三氯生的性质、毒性及其在水体中存在的情况。考虑到三氯生在自然条件下会转化成致癌物等多种有毒有害物质,因此建议需要从源头对三氯生进行控制和去除,为后续饮用水的安全提供保证。本文对几种高级氧化技术降解三氯生的机理,影响因素,处理效果存在的问题及解决方法等进行了归纳总结。同时还对具有应用前景的光催化技术就催化剂的制备改性、机理研究、回收利用及与其它工艺组合等方面进行了展望,并预测光催化技术与其他技术组合是未来水处理研究的一个重要方向。Triclosan,as one of broad spectrum antimicrobial agent of PPCPs,was introduced in the article on its physical properties,toxicity and status in aquatic environment,briefly.Considering varieties of hazardous substances produced by triclosan in natural conditions,triclosan should be controlled and removed from sources which can guarantee the safety of drinking water.The article summarize the properties,the existing problems and the resolving methods as well as the mechanisms,influencing factors and removal effects for removing TCS by advanced oxidation processes（AOP）.The paper also indicated the orientation of photocatalytic technology with preparation,mechanism,recycle and combination with other technologies and predicts that the combination of photocatalytic technologies with other technologies was an important research field applied to water treatment in future.
