玻璃面板蚀刻含氟废水的处理研究进展

Research Progress in Treatment of Fluoride Wastewater from Glass Panel Etching

随着氟资源在现代化工业中的广泛应用,含氟废水的排放问题也需要解决。本文基于玻璃面板蚀刻含氟废液的处理问题重点介绍了处理含氟废水常用的沉淀法、吸附法,简单介绍了电化学法、反渗透法、离子交换法。在说明这些方法处理含氟废水的应用情况的基础上,结合工程实例评价了这些方法的优缺点。

With the wide application of fluoride resources in modern industry,the discharge of fluoride wastewater also needs to be solved.In this study based of the problems of the treatment of fluoride wastewater from glass panel etching we introduce the commonly used precipitation,adsorption methods for the treatment of fluoride wastewater briefly introduce the electrochemical,reverse osmosis,ion exchange methods.On the basis of explaining the application of these methods in the treatment of fluoride wastewater,the advantages and disadvantages of these methods are evaluated combined with engineering examples.
