将混凝沉淀法应用于低浓度含氟废水处理，同时对其影响因素进行了系统的研究。结果显示：当进水pH控制在6.6~7.0，PAC投加量为800 mg/L，PAM投加量为3 mg/L时，可将原水中氟离子质量浓度从20 mg/L降至5.0 mg/L，远远低于国家规定的《污水综合排放标准》（GB 8978-1996）中的一级排放标准。

The coagulation precipitation method has been applied to the treatment of wastewater containing fluoride with low concentration,and its influencing factors have been studied systematically. The results show that when the influent pH is in range of 6.6-7.0,PAC dosage is 800 mg/L,and the dosage of PAM is 3 mg/L,the fluoride ion con-centration in the raw water can be reduced from 20 mg/L to 5.0 mg/L ,far less than the first level of state-stipulated Integrated Wastewater Discharge Standard(GB 8978-1996).
