高效氧化铝除氟剂及其除氟实用技术的研究

研究了选用经过特殊工艺处理的活性氧化铝作为高氟原水的除氟剂。在除氟剂对氟含量为10mg／L的原水处理试验中，当流速在80ml／min以下时，其终端流出水中的氟含量小于lmg／L；除氟剂的绝对饱和吸附量和相对饱和吸附量分别为1．67mg／g和1．57mg／g，再生活化后可恢复良好的除氟性能。研究结果显示活性氧化铝具有很好的实用前景。

Studies on the Activated Aluminum Oxide as a Fluorine-removal Agent and its Application

An activated aluminum oxide processed under a specific way was used as fluorine - removal agent for the treatment of fluorine - contained water. Original water was prepared by adding fluorine to 10mg/L in the experiment of fluorine - removal treatment. While the flowing rate of water was controlled at less than 80ml/min , the fluorine concentration of the end - flowing water was less than 1 mg/L. The absolute and relative saturated adsorptive were 1. 67mg/g and 1.57mg/g respectively. The results were also shown that the regeneration technique was very suitable to restore the fluorine - removal performance, The experiment indicates that activated aluminum oxide is very useful in the field application.
