| Abstract: | The fluoride ions of quartz industrial wastewater were purified by chemical precipitation, coagulation and auxiliary coagulation using calcium chloride, polymeric aluminum chloride and polyacrylamide respectively. The results showed that the effects had been obviously affected by pH, dosage of reagent, adding order and reaction time. The fluoride ion concentration of wastewater were degraded from 100 mg/L to 8 mg/L under the condition of simulating mineral processing wastewater. Optimized conditions were used to deal with the fluoride ions of quartz industrial wastewater, and it meet the criteria of the nation first grade standard. It will provide a technical support for purification of industrial wastewater containing fluoride. |
