摘　　要：随着各地污废水排放标准的提高,对含氟废水进行深度处理的需求日益增长。目前较为常用的几种除氟工艺主要有:化学沉淀法,混凝沉淀法,吸附法,电化学法,离子交换树脂及各类复合工艺。对比后发现吸附法、离子交换树脂及混凝沉淀法是较为适合的低浓度含氟废水的深度处理技术,而其中混凝沉淀法应用场景则最为广泛。With the increase of wastewater discharge standards in various regions,the demand for advanced treatment of fluoride wastewater is growing.This article analyzes several commonly used fluoride technologies,including chemical precipitation,coagulation precipitation,adsorption,electrochemical treatment,ion exchange resin,and various composite processes.After comparison,it was found that adsorption,ion exchange resin,and coagulation precipitation are more suitable for the deep treatment of low-concentration fluoride-containing wastewater,among which coagulation precipitation has the widest application scenario.
