Progress of research and application of coagulation defluorination technology
Fluorides are widely present in nature,and the rapid development of industrial production activ-ities also generates a large amount of fluoride wastewater,which seriously endangering human health and ecologi-cal environment.Among many defluorination methods,coagulation has been widely applied due to its advantages of low cost,high efficiency and simple operation.The research progress of defluorination coagulants,the main factors influencing the fluoride removal by coagulation and the current status of defluorination by coagulation combined processes,were elaborated;besides,the future research direction of coagulation defluorination was prospected.
