摘　　要：碘代造影剂(iodinated contrast media,ICM)是药物和个人护理产品中的一种,被广泛应用于医学临床检查和治疗.ICM稳定的结构使其难以在污水处理厂中降解,从而在地表水和地下水中聚集.ICM在饮用水消毒过程中还会转换成毒性更强的消毒副产物,对生态环境和人体健康造成严重威胁.因此,国内外学者现已提出多种技术去除水体中的ICM,本文从物理法、生物法、高级氧化法3个方面,系统地总结了当前ICM废水处理技术研究现状,并对今后ICM处理技术的研究趋势进行了展望,为难降解污染物的处理提供了新的思路.Iodinated contrast media(ICM)is one of the pharmaceutical and personal care products(PPCPs),which is widely used in medical clinical examinations and treatments.ICM is difficult to be eliminated in sewage treatment plants because of its stable structure.Thus,it will be accumulated in surface water and groundwater.ICM can also be converted into more toxic disinfection by-products in the process of drinking water disinfection,which poses a serious threat to the ecological environment and human health.Therefore,scholars at home and abroad have proposed a variety of technologies to remove ICM in water environment.This paper systematically summarizes the current research progress of ICM wastewater treatment technologies from three aspects:physical,biological and advanced oxidation method.The research trend of ICM treatment technologies in the future has been prospected,which provides new ideas for the treatment of refractory pollutants.
