新污染物在污水处理厂中的赋存及去除现状研究

Research on the Occurrence and Removal Status of Emerging Contaminants in Wastewater Treatment Plants

以污水处理厂中的新污染物为研究对象,选取四类典型新污染物(即持久性有机污染物、抗生素、内分泌干扰物和微塑料)开展研究,解析了其进入污水处理厂的来源,分析了其在不同污水处理工艺中的赋存状态及降解现状。为更好地对比分析新污染物降解途径,本文对当前新污染物去除技术进行探讨及比对,进而指出了污水处理厂中新污染物去除技术的发展趋势,从而为污水处理厂中新污染物高效去除的新技术及新工艺研发提供了宝贵借鉴。

The article takes emerging contaminants in wastewater treatment plants as the research object,selects four typical emerging contaminants(persistent organic pollutants,antibiotics,endocrine disrupting chemicals and microplastics)to conduct research,analyzes their sources of entering wastewater treatment plants,and analyzes their occurrence and degradation status in different wastewater treatment processes.In order to better compare and analyze the degradation pathways of emerging contaminants,this article discusses and compares current emerging contaminants removal technologies,and then points out the development trend of emerging contaminants removal technologies in wastewater treatment plants,providing valuable references for the research and development of new technologies and processes for efficient removal of emerging contaminants in wastewater treatment plants.
