水环境中全氟化合物的去除技术研究综述

Research Overview of Technology of Perfluorinated Compounds Removal in Water Environment

全氟化合物(PFCs)是环境中普遍存在的一类污染物质,具有持久性、生物放大性和难降解性。文中介绍了目前水环境中PFCs的主要去除技术,包括物理法、化学法和生物法,阐述了其主要降解效果和降解机理,并比较其优缺点,以期为控制PFCs的污染技术发展提供参考。此外,建议将不同处理技术耦合,开发高效经济的去除方法以减少PFCs的污染。

Perfluorinated compounds （ PFCs） are the kind of pollutants that exist ubiquitously in the environment with persistence, biomagnification and refractory properties. In this paper, the authors introduce the major methods to remove PFCs in water, including physical, chemical,and biological methods,and also summarize the removal effects and mechanisms of each technology,and compare their advantages and disadvantages in the purpose of providing reference for the further related removal technologies of PFCs. In addition,it is suggested that researchers should work on coupling several methods to develop more economic and effective approaches to remove PFCs in water in order to control PFCs pollution.
