摘　　要：文章根据化学沉淀法和同离子效应,推导出用氯化钙处理含氟废水所需的理论投加量,并采用氯化钙-聚合氯化铝联合处理某铝加工工厂高浓度含氟废水,此种废水平均含氟浓度为500 mg/L,pH=6-7,效果较好,达到了国家排放标准,并据此提出了该厂污水处理工艺。The paper was based on the chemical precipitation and the same ion affection theories, derived the theoretical dosage of fluoride containing wastewater with calcium chloride, and conducted the highly concentrated fluoride-containing wastewater of the aluminum processing factory with calcium chloride-polyaluminum chloride, the average concentration of fluoride ion was 500 mg/L and the value of pH was 6-7, which had a good effect and reaches the national emission standard, and put forward the process of the wastewater.
