摘要
近年来,个人护理品(personal care products,PCPs)的使用量越来越大。PCPs通过多种途径持续不断地被排放到环境介质中而被频繁检出,对生态环境与人体健康产生一定的风险,其关注度越来越高。PCPs使用后随洗漱和洗浴过程进入生活污水处理系统,大部分通过物理、化学和生物方法被去除,残余的PCPs和代谢产物随着污水厂的尾水排入水体。水环境的PCPs其它来源还包括游泳、消毒、化妆等。总结了PCPs的来源与种类、在水环境的赋存现状、归趋及潜在环境影响,评述了污水处理过程中PCPs的常规与深度处理技术,最后针对PCPs等新兴污染物的去除工艺的选择和优化等提出了建议。
In recent years,personal care products(PCPs)have been increasingly used.PCPs are continuously discharged into environmental media through a variety of ways and are frequently detected,and caused widespread attention for their potential risks to human health and ecological environment.PCPs enter the domestic sewage treatment system along with the washing and bathing process,and most of them are removed or degraded through physical,chemical and biological methods.The residual PCPs and metabolites are discharged into water bodies along with tail water of the sewage plant.Other sources of PCPs in water environment include swimming,disinfection and cosmetics and so on.This paper summarized the sources and categories,current status,fate and potential environmental impacts of PCPs in water environment,reviewed the conventional and advanced treatment technologies of PCPs in domestic sewage treatment process,and finally put forward suggestions for the selection and optimization of removal technologies of emerging pollutants such as PCPs.
