活性氧化铝处理含氟地下水
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. Abstract: 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. 作 者: 武道吉 李秋梅 尹萌萌 孙梅 李满 张丽 WU Dao-ji LI Qiu-mei YIN Meng-meng SUN Mei LI Man ZHANG Li 作者单位: 武道吉,李秋梅,尹萌萌,李满,张丽,WU Dao-ji,LI Qiu-mei,YIN Meng-meng,LI Man,ZHANG Li(山东建筑大学市政与环境工程学院,山东,济南,250101)孙梅,SUN Mei(济南工程职业技术学院,山东,济南,250200)
