INFLUENCE OF PROPERTY-MODIFICATION OF DIATOMITE ON REMOVING FLUORINE IN INDUSTRIAL WASTEWATER

Property_modified diatomite was used to remove fluorine in industrial wastewater. The micro_structure and physicochemical characteristics of Shengxian diatomite were studied before and after the property modification. The results show that the hole volume and the ratio of surface area of the property_modified diatomite are increased, and its pile density is decreased. As a result, the ability of property_modified diatomite removing fluorine in industrial waster water by its absorption and chemical reaction with fluorine is significantly increased.
