摘　　要：综合比较了不同活化剂对Al2O3除氟能力的影响,从而选定Al2(SO4)3为活化剂;并对活化和再生方法进行了研究,提出了最佳的活化和再生工艺参数:对于Al2O3使用前的活化,采用4%Al2(SO4)3以滤料/活化剂=1∶1的体积比活化4h即可取得良好的效果;而Al2O3吸附饱和后,再次使用前要再生以恢复其除氟能力,对于本试验使用的Al2O3,采用4%Al2(SO4)3再生2h即可取得良好的再生效果。This paper comprehensively compared various impacts on removing fluorin of Al2O3 activated by different agents. And Al2 （SO4）3 was determined as the effective activated agent; moreover, activated and regenerated methods were also studied in this paper, the optimal process parameters of activation and regeneration were determined as follows： Al2O3 was activated by 4% Al2 （SO4）3 at the volume ratio of Al2O3 to groundwater 1 ： 1 during 4 hours ; for the regeneration of used Al2O3 , 4% Al2 （ SO4 ） 3 in 2h can achieve good result.
