摘　　要：采用混凝沉淀工艺去除高氟水中的氟是一种有效的方法,但在除氟过程中影响因素较多.采用PAC作为高效混凝剂,通过试验研究,分析了在原水含氟量为10mg/L时,混凝剂投加量、pH值、水温、原水硬度、浊度及水中共存的几种干扰离子对混凝沉淀除氟工艺的影响情况,得出了PAC的最佳投药量、除氟的最适宜pH值范围等,并对其他几种影响因素得出了定性的结论.The coagulating sedimentation method for fluorine removal is an effective method.But there still exists some influence factors during the removal process.Using poly aluminum chloride（PAC）as a high coagulant,as the fluorine concentration is 10 mg/L in the raw water,this paper analyzes how the influence factors,such as coagulant dosage,pH,temperature,raw water hardness,turbidity and coexist ions in water,etc.,disturb the fluoride removal in this technology.Through the experimental study,the optimal dosage of PAC and the optimum scope of pH for fluorine removal are found.Also,some qualitative conclusions for other influence factors are drawn.
