| Abstract: | The high concentration fluoride wastewater was treated with chemical precipitation method. It was investigated that effect of the fluoride removed was influenced on amount of the precipitant, the ratio,pH of the solution, temperature, the time of mixing, reaction and standing sedimentation. The temperature was under 50 ℃, emulsion of rt（Ca2＋）/n（F-） in 2.5,pH 8.0, the reaction time of 10 rain, standing sedimentationtime of 2 h. The results showed that the concentration of fluoride ion was less than 10 mg/L, below the wastewater discharge standards by the treatment. |
