| 摘 要： | 本文开展了山西运城地区高氟地下水的降氟试验，对聚铁、硫酸铝和明矾等不同混凝剂降氟效果进行对比，探讨了地下水硬度对混凝沉淀除氟效果的影响。实验结果表明：明矾混凝沉降效果优于其它混凝剂，0．3g／L的明矾溶液可使含氟浓度4．0mg／L的地下水降低到浓度1．0mg／L以下；地下水的硬度对明矾混凝降氟效果没有明显影响。

| Abstract: | Effective fluoride removal technology is very important for people who drink high fluoride-bearing groundwater. A trial experiment of fluoride removal from high fluoride-bearing groundwater in Yuncheng Basin, Shanxi Province, is conducted and discussed in this paper. Several coagulants have been compared in this experiment, and the influence of the hardness of groundwater has been investigated. Experiment results indicate that alum is the best choice as a coagulant, and that for coagulative precipitation process using alum solution at 0.3 g/L has been successfully applied for fluoride removal from fluoride-bearing water whose initial concentration is less than 4 mg/L.Hardness of the groundwater is not important. |
