摘　　要：通过吸附及混凝沉淀除氟实验,证明以聚合氯化铝(PAC)为混凝剂除氟非常有效.在PAC加入量为35mL/L,pH在7.26~7.66之间,温度为室温,静置搅拌时间为20min的条件下,处理含氟为13.57mg/L的水样,氟离子的去除率达到93.52%.该方法可有效去除水中的氟离子,达到国家饮用水标准.In this paper, adsorption and coagulative precipitation defluorination experiments prove that the PAC is very effective for fluoride removal coagulant. To join in the PAC of 35 mL/L, pH at between7.26~7.66, the temperature is at room temperature, holding for 20 minutes stirring time conditions, to deal with fluoride to 13.57 mg/L in water samples, the removal rate of fluoride ion reached 93.52%. Effective removal of fluoride ions, up to the national drinking water standards.
