Study on the Treatment of Fluorine Containing Wastewater with Fly Ash Ceramisite;

Experiments on treatment of wastewater containing fluoride by Polysilicate-metals Salts;

the feaslbility of treating wastewater containing fluoride 190 mg/L and pH7.

The industrial wastewater containing fluoride are harmful to environment.

Treatment of fluoride wastewater of color display with sludge cycled technology;

Studies on purifying technology of fluoride wastewater are introduced as well as the mechanism and their applications.

The treatment process of the wastewater that is produced in the microeletronic industry chip manufacture field is expounded,including fluoride wastewater and silica grind wastewater and the high acid and caustic concentration wastewater coming from the mixed bed regeneration in the D.

This paper has simply summarized on the application and research of the internal processing of fluoric wastewater in recent years, and shows the development of the research on the processing of fluoric wastewater .
