摘要
以含氟化物的矿井废水为研究对象,比较了两种聚合硫酸铁(FPS)和聚合氯化铝(PAC)混凝剂的除氟效果,研究了混凝剂的不同投加比例、沉淀剂以及p H值对矿井废水除氟的影响,确定了含氟矿井废水的最佳混凝反应条件,并将其应用于工程实践,为含氟矿井废水治理提供了技术支持。
Taking fluoride-containing mine wastewater as a research object, the effects of FPS and PAC coagulants for removing the fluoride were compared. The influence of coagulant dosage, precipitant and pH on removal rate of the fluoride was studied. The best coagu-flocculation condition was determined, and the coagu-flocculation process was applied in practical projects.
