中国水环境中全氟化合物的污染水平及控制策略

摘要

The pollution status of perfluorinated compounds(PFCs) in the water environments,such as surface water,drinking water and wastewater,over China was introduced in this paper.It was observed that a general pollution of PFCs existed in various water environments,and the pollution level in some places,especially the industrial and densely populated areas,exceeded the average conditions overseas.The main pathways of PFCs pollutions in soil,water and air include the discharge of PFCs from manufacturers and daily use.Common control technologies for PFCs pollutions include advanced oxidation,biodegradation,and adsorption etc.Extended studies on PFCs pollutions in various water environments,especially in groundwater and sediment,would help further understanding on mechanisms of PFCs transformation and degradation,investigation on low-cost and efficient methods of the control of PFCs pollution.%介绍了我国水环境（地表水、饮用水和污水）中全氟化合物（PFCs）的污染状况,发现各种水体中普遍存在PFCs污染,局部地区特别是工业和人口密集地区的PFCs污染水平超过国外。PFCs主要通过含氟产品生产及使用进入土壤、水和空气等生态环境;目前对PFCs污染的控制方法主要有高级氧化、生物降解、吸附分离等。未来的研究方向将是加强各种环境尤其是地下水和沉积物中PFCs污染状况的研究,深入了解PFCs的迁移和降解机理,同时积极研发经济高效的PFCs污染控制方法及其替代品。
