水环境中药物及个人护理品(PPCPs)的生物降解研究进展

A review of biodegradation of pharmaceuticals and personal care products( PPCPs) in aqueous environment

总结国内外水环境中药物及个人护理品(PPCPs)的生物降解研究现状,详述PPCPs在污水处理系统和地表水环境中的生物降解动力学方程,分析水力停留时间、污泥龄和温度等影响生物降解的主要因素,评述单一菌种和活性污泥中的混合菌种对典型PPCPs的降解路径,并对今后PPCPs生物降解领域的研究进行了展望。

This paper presents a review of current research on the biodegradation of pharmaceuticals and personal care products （PPCPs） in the aqueous treatment systems and surface water. environment and elaborates on biodegradation Dominant factors, including hydraulic reten kinetics of PPCPs in sewage tion time, sludge age, and temperature, which influence the biodegradation, are analyzed. The biodegradation pathways of single bacteria and mixed microorganisms in activated sludge are summarized for typical PPCPs classes. Furthermore, research topics related with biodegradation of PPCPs are proposed.
