针对常用的除氟工艺存在的缺点,以高氟地热水处理为研究对象,研究利用电絮凝法除氟过程.结果表明,电絮凝法处理高氟地热水的最佳工艺参数为面体比80m~2/m~3、极板间距0.5cm和电流密度10A/m~2,电耗为2.13kWh/t,酸性或中性水和较高的水温有助于提高处理效果.电絮凝法除氟机理为可溶性的铝电解产生Al~(3+)离子在适宜的pH值时形成Al(OH)~3,最后转换成Al_n(OH)_(3n),通过絮凝作用将氟化物去除.

According to shortcoming of commonly fluorine removal treatment technology, the fluorine removal process with electric flocculation is investigated with high fluoride geothermal water treatment as the research object. The result shows that the optimal parameters are area/volume ration80m~2/m~3, distance between polar plates 0.5cm, current density 10A/m~2, respectively. The power consumption is 2.13kWh/t. The result of treatment is improved by acid or neutral water and higher water temperature. The fluorine removal mechanism with electric flocculation is in suitable pH condition, Al(OH)~3 forming from soluble Al~(3+). The Al(OH)~3 are changed into Al_n (OH)_(3n) finally, fluoride are removed by flocculating function.
