城市污水处理厂中药品及个人护理品的去除研究

Research on Removal of PPCPs in Municipal Wastewater Treatment Plant

PPCPs原药及其代谢产物进入污水处理系统,会对生物处理进程产生负面影响,此外,这些代谢产物在接受水体中会进一步转化,成为毒性更强的污染物,因此传统的污水处理技术已不能满足当前污水处理的需要。先进的处理方法应运而生,包括膜过滤、活性炭处理、臭氧氧化和人工湿地法等,大量研究表明,这些技术对去除PPCPs单体具有良好的效果。本文介绍了目前污水处理厂常用的PPCPs处理技术,分析了污水处理中影响PPCPs去除效果的因子。

PPCPs and their metabolites enter the sewage treatment system,which will have a negative impact on the biological treatment process,in addition,these metabolites will be further transformed in the receiving water body and become more toxic pollutants,therefore,the traditional sewage treatment technology can no longer meet the current sewage treatment needs.Advanced treatment methods have emerged,including membrane filtration,activated carbon treatment,ozone oxidation,and constructed wetland methods,a large number of studies have shown that these technologies have a good effect on the removal of PPCPs monomer.This paper introduces the PPCPs treatment technology commonly used in sewage treatment plants,and analyzes the factors that affect the removal of PPCPs in sewage treatment.
