摘要

以含氟饮用水为研究对象,分别采用人工冷冻和自然冷冻法对高氟饮用水进行分离净化研究.实验结果表明:冷冻处理能够有效降低高氟水中氟离子含量,达到国家饮用水标准;人工冷冻在-5～-25℃的温度下处理2～8 mg/L的高氟水,氟离子浓度在0.6 mg/L以下;温度在-10～-20℃条件下处理效果较好,冰层融水中氟离子含量平均在0.52 mg/L,冰融水中氟离子可以得到很好的去除;冰层融水中氟离子浓度随原水浓度的升高而增大.
Fluoride solution was selected as the sample in this study.Artificial freezing and natural cold method was use to study the fluoride solution purification.Result indicates that freezing treatment can reduce the fluoride concentration to reach the standard of the drinking water.Under the artificial freezing condition to treat with 2～8 mg/L fluoride concentrationt,he water quality is affected better in the temperature in the range of-10～-20 ℃ and the fluoride concentration is 0.52,mg/L.As the temperatures in the range of-5～-25 ℃t,he concentration of F-is lower than 0.6 mg/L.The concentrations of F-increased in ice layers while the samples′ concentrations increased.
