In recent years,with the vigorous development of fluorine industry,the discharge of industrial fluorinated wastewater has increased rapidly year by year,which has caused adverse effects on human health and environment.Domestic scholars have made a lot of experiments on the treatment of industrial fluorinated wastewater with different concentrations and different types,and the research results have been widely used in practice,but there are widespread problems of high treatment cost and unstable treatment effect.The shortage of water resources is a big problem in China,wastewater reusing for production is a good way to save water resources,so the state now is promoting near zero discharge wastewater treatment,in order to achieve sewage resources.With the increasingly strict discharge standards of fluoride,the development of new method combinations and new materials which are more suitable for engineering practice to achieve low cost and high efficiency defluorination and reuse will become the focus of future research.
