水环境中药物类PPCPs的赋存及处理技术进展

Review on Occurrence and Treatment Technology of PPCPs in Water Environment

药品和个人护理品(PPCPs)类新兴污染物在水环境中被广泛检测出,因其生物累积性和潜在的生态危害性,近年来受到高度关注。文中总结了水环境中PPCPs的赋存状况,解析了水环境中PPCPs的来源和迁移、转化路径,发现传统污水处理厂尚不能彻底、有效地去除PPCPs,污水厂的尾水排放是水环境中PPCPs的重要来源。同时,比较了污水厂常规处理和三级处理工艺对PPCPs的去除效果,指出污水处理厂基于宏量常规污染物和微量新兴污染物的同步去除技术或复合去除技术是削减水环境新兴污染物浓度的核心途径,开发能够经济、高效地去除各类PPCPs的深度处理技术仍然十分必要。

Emerging pollutants such as pharmaceuticals and personal care products(PPCPs)have been widely detected in water environment,and have aroused tremendous attention in recent years due to their bioaccumulation and potential ecological hazards.The sources,migration and conversion routes of PPCPs in water environment summarized.It is found that some kinds of PPCPs can’t be completely or effectively removed in traditional wastewater treatment plants,and the effluent discharged from wastewater treatment plants is an important source of PPCPs in water environments.Moreover,removal effects of the PPCPs in conventional treatments and tertiary treatment processes are compared.It is suggested that simultaneous removal technologies or integrated removal technologies of wastewater treatment plant based on macro-conventional pollutants and trace emerging pollutants are the core approaches to reduce the concentration of PPCPs in water environment.And it is still necessary to develop advanced treatment technologies that can efficiently remove various types of PPCPs.
