摘　　要：根据广州某公司特定的含氟废水,探讨了含氟废水的处理机理和处理工艺流程。实验表明:用熟石灰调pH值,同时采用沉淀剂氯化钙+混凝剂PAC的联合处理,可使含氟废水的氟离子浓度下降到10mg/l以下,达到国家污水综合排放的一级标准。The mechanism and technological process of treatment on fluoride - containing wastewater are discussed according to the specific wastewater of a company in Guangzhou. The experimental results show that ： the concentration of fluoride ion in wastewater will reduce to I0 mg/L with the combined treatment of precipitation agent calcium chloride and coagulant PAC, and hydrated lime for adjusting pH value, which reaches the national level of integrated wastewater discharge standard.
