Abstract:

The highly concentrated fluoride-containing wastewater discharged from a quartz-producing enterprise has been treated by preliminary sedimentation-coagulation precipitatiobn-adsorption process. The results of engineering practice show that when the dosing amount keeps stable,the mass concentration of effluent fluoride can be controlled steadily under 5 mg/L,reaching the discharge standards required by the local Environmental Protection Agency.

Key words: fluoride-containing wastewater, coagulation precipitation, adsorption

摘要：

针对某石英制品企业排放的高浓度含氟废水，采用初沉-混凝沉淀-吸附组合工艺进行处理。工程实践结果表明：在加药量维持相对稳定的情况下，出水氟化物质量浓度可稳定控制在5 mg/L以下，达到了当地环境保护局要求的控制标准。
