活性氧化鋁處理含氟地下水
摘要: 綜合比較了不同活化劑對Al2O3除氟能力的影響,從而選定Al2(SO4)3為活化劑;并對活化和再生方法進行了研究,提出了最佳的活化和再生工藝參數:對于Al2O3使用前的活化,采用4%Al2(SO4)3以濾料/活化劑=1∶ 1的體積比活化4h即可取得良好的效果;而Al2O3吸附飽和后,再次使用前要再生以恢復其除氟能力,對于本試驗使用的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 孫梅 李滿 張麗 WU Dao-ji LI Qiu-mei YIN Meng-meng SUN Mei LI Man ZHANG Li 作者單位: 武道吉,李秋梅,尹萌萌,李滿,張麗,WU Dao-ji,LI Qiu-mei,YIN Meng-meng,LI Man,ZHANG Li(山東建筑大學市政與環(huán)境工程學院,山東,濟南,250101)孫梅,SUN Mei(濟南工程職業(yè)技術學院,山東,濟南,250200)
