【摘要】 本文研究了活性氧化铝的预处理措施及机理,并通过静态和动态吸附试验研究了经不同预处理后活性氧化铝的吸附性能。结果表明,硫酸铝溶液浸泡可显著改善活性氧化铝的吸附性能,即:活性氧化铝经2%硫酸铝溶液浸泡后,用于氟含量为3.7 mg/L的高氟水处理,其初始出水氟浓度降低至1.0 mg/L以下,穿透吸附容量1.532 mg/g,穿透BV值可达342。更多还原

【Abstract】 The measures and mechanism for pre-treatment of the activated alumina are studied herein,and then the adsorption performances of the activated alumina after various pre-treatments are also studied through static and dynamic adsorption tests.The results show that the adsorption performance of the activated alumina can be significantly improved after being marinated with in aluminum sulfate solution;i.e.if the activated alumina marinated with the aluminum sulfate solution with the content of 2% is applied to the treatment of the high fluorine water with fluorine content of 3.7 mg/L,the fluorine content of the initial out-water after the treatment would be lowered to below 1.0 mg/L with the penetrable adsorption capacity of 1.532 mg/g and the penetrativity BV reaching to 342.更多还原
