工业废水氟污染及其去除技术的研究进展OA

High-concentration fluoride pollution poses a severe threat to human health,and its primary sources are the modern industrial produc-tion processes of fluorine-based chemicals,including aluminum electrolysis,phosphate fertilizer production,iron and steel smelting,coal chemical engineering,and semiconductor manufacturing.This paper systematically sorts out the current status and discharge standards of typical industrial fluoride pollution,and focuses on reviewing the principles,treatment efficiencies,as well as advantages and disadvantages of mainstream deflu-orination technologies,such as precipitation,adsorption,membrane separation(including nanofiltration,reverse osmosis,and electrodialysis),ion exchange,and electrochemical methods.On this basis,the current development and future trends of fluoride removal technologies are further dis-cussed,which provides insights for future research directions.
