摘　　要：目的通过对经特殊工艺处理的不同粒径的活性氧化铝的除氟性能进行研究,开发实用的除氟剂.方法模拟A(粒径2.0～3.0 mm)、B(粒径3.5～5.5 mm)样除氟剂对氟含量为10 mg/L的原水进行处理试验,研究除氟性能.结果 A、B样除氟剂当流速分别为80 ml/min及以下和20 ml/min及以下时,其终端流出水中的氟含量均小于1 mg/L; A、B样除氟剂的绝对饱和吸附量分别为1.67 mg/g和1.30 mg/g,相对饱和吸附量分别为1.57 mg/g和0.17 mg/g.结论除氟剂粒径小、比表面积较大时,有利于除氟性能的提高.Objective To dew, lop a applicable fluorine-removal agent, two types of activated aluminum oxide processed under a specific way were used as fluorine removal agents for the treatment of fluorine-contained water. Methods Original water was prepared by adding fluorine to 10 mg/L.in the experiment of fluorine-removal treatment. Results While the flowing rate of water was controlled at ≤80 ml/min and ≤20 ml/min for fluorine removal agent A and B respectively, both fluorine concentrations of the end flowing water were less than 1 mg/L. The absolute saturated adsorptive amount of A and B was 1.67 mg/g and 1.30 mg/g respectively, and the relative saturated adsorptive amount was 1.57 mg/g and 0.17 mg/g respectively. Conclusion Reducing the diameter and enlarging the specific area of the agent is helpful to the improvement of the fluorineremoval ability.
