摘　　要：PhACs(pharmaceutically active compounds)作为一类"新兴"污染物,由于持续不断地排放及对人类和野生生物的潜在毒性风险,引起了科学界和公众的广泛关注,成为当前环境科学与工程领域的研究热点。NSAIDs(nonsteroidal anti-inflammatory drugs)作为PhACs的一大组成部分,在水环境中普遍检出。本文以非甾体抗炎药(NSAIDs)为研究对象,综述了它们在常规城市污水处理过程中的去除特性。由于污水处理厂的不完全去除是水环境中PhACs的主要来源途径,出水的深度处理工艺的研究与开发势在必行。文章第二部分重点探讨了目前国内外研究的几种去除NSAIDs的不同的深度处理工艺,最后对PhACs污染的研究方向进行了展望。Pharmaceutical active compounds（PhACs） which was a class of emerging contaminance had raised worldwide concern from scientists and the public during recent years and regarded as ＂pseudopersistent＂,due to their continual discharge and their potential toxic effects on wildlife and humans.Because of incomplete treatment of conventional sewage treatment plants,sewage effluents are widely recognized as the main source of PhACs,A large fraction of PhAC pollution in water was composed of nonsteroidal anti-inflammatory drugs（NSAIDs）which were usually detected in the aquatic environment.The first part of this paper reviewed the removal characteristics of NSAIDs residues in conventional sewage treatment plants,the second part focuses on the advanced treatment processes that were promising solutions to the ultimate degradation and/or conversion of such medical residues in sewage effluents,finally,the future research direction was prospected.The aim of this paper was to provide theoretical guidance and reference for the research and development of PhACs reduction and advanced treatment technologies.
