摘　　要：采用双铝电絮凝法去除饮用水中的氟。研究了电极间距、原水pH值、原水氟浓度、电流密度对除氟的影响。结果表明,电絮凝法去除地下水中的氟不需添加可溶性盐和改变pH值,在选定的实验条件下,阳极面积与反应器容积比为52.5m2/m3,电极间距1.0cm,电流密度30A/m2,反应10min后,出水中F-浓度符合国家饮用水卫生标准。The present paper introduces the authors＇ study on a new method for removing fluoride from the drinking water by using aluminum diodes. The method has been developed on the basis of the influence of parameters such as inter-electrode space, the pH of the solution, the fluoride concentration and the current density on the electrocoagulation process. The results of the present study has shown that when the area/volume ratio, the interlectrode space, the current density, and the operation time are 52.5 m^2/m^3, 1.0 cm, 30 A/m^2 and 10 rain respectively, the fluoride concentration of the effluence above 1.0 mg/L can be expected to meet the sanitary standard for drinking water （GB 5749-85） once it is properly treated through the electrocoagulation process without adding soluble salts to the groundwater and then turning the pH value of the solution into the proper concentration.
