聚合硫酸铁除氟效果的研究

Study on Removing Fluoride With Polyferric Sulfate

研究了聚合硫酸铁(PFS)对高含氟废水样的混凝处理,探讨了PFS的用量、初始pH值、反应时间分别对除氟效果的影响。结果表明,当絮凝剂PFS的用量为35ml/L,水样初始pH值为7.0,反应时间为25min时,F-的去除率可达96%以上。

Polyferric sulfate is a new inorganic coagulant used in treatment of municipal water and industrial waste water.In this paper,waste water containing high concentration fluoride was treated with polyferric sulfate.And effect of PFS dosage,initial pH,reaction time on fluoride removal was investigated.
