摘　　要：全氟化合物(PFCs)作为一种完全氟化的有机物,具有极强的物理及化学稳定性,难以用常规处理方法去除。由于PFCs对人类健康的危害极其严重,如何有效地去除全氟化合物是水处理的一个重要研究方向。文章选取全氟化合物中的全氟辛酸(PFOA)及全氟辛烷磺酸盐(PFOS)作为主要论述对象。文章主要列举了4种处理方式,包括:吸附去除法、膜处理法、高级氧化法及一些新型技术。就去除效率而言,结合吸附去除法及膜处理法是最理想的处理方式,然而花费较高。因此,吸附去除法是目前处理全氟化合物最实用的方法之一。Perfluorinated compounds(PFCs)is a kind of totally fluorinated organic compounds.Usually,PFCs is too stable to be removed.However,because PFCs can stay in natural waterbody in a very long time and is harmful to human being,removing PFCs in eff iciently is a very important topic in water treatment science.The common control methods of PFCs have been listed,including adsorption removal process,membrane treatment process,advanced oxidation process,and some new techniques.In terms of eff iciency,the best way to remove PFCs is to combine adsorption and membrane treatments;however,the cost stands high.Thus,adsorption turns out to be the most practical solution,which is the main point of this paper.
