地下水中除氟方法研究进展

The Research Progress of Fluoride Removal Methods in Groundwater

为降低饮用水中氟化物对人体健康的危害,目前国内外研究者已经对高含氟地下水中的F-的去除做了大量的研究工作,并提出了许多可行性方法,例如沉淀法、离子交换法、膜分离法、吸附法等。因此本文综述了近年来国内外高含氟废水除氟方法的研究进展,并进一步分析了这些方法的技术瓶颈,展望未来主要发展趋势,以期为高含氟废水处理技术的进一步研究提供参考。

To mitigate the risk to human health from fluoride in drinking water.Researchers,domestic and foreign,have done a lot of research on the defluorination work in highly fluoridated groundwater,and have presented many feasible methods,such as precipitation,ion exchange,membrane separation,adsorption and so on.Therefore,the research progress on fluoride removal methods for highly fluorinated wastewater was reviewed in recent years.By further analyzing the technical bottlenecks in the fluoride removal methods,the main future development trends was prospected,in order to provide references for further research of highly fluorinated wastewater treatment technology.
