摘要
研究了吸附柱柱高、原水氟离子浓度、流速、活性氧化铝粒径等因素对氢氧化钠改性活性氧化铝动态除氟效能的影响。结果表明,氢氧化钠改性活性氧化铝的动态除氟效果明显好于未改性活性氧化铝。通过测定动态吸附容量发现:氢氧化钠改性活性氧化铝的吸附容量是未改性活性氧化铝吸附容量的6.7倍,表明改性活性氧化铝对氟离子具有良好的吸附去除效能。
The paper studied the impact of factors such as the height of adsorption column,initial concentration of fluorinated water,velocity of flow and activated alumina grain diameter on the dynamic defluoridation performance of the sodium hydroxide modified activated alumina.The result indicated that the effect of the defluoridation by the sodium hydroxide modified activated aluminum was better than that of the unmodfied activated alumina.The determination of the dynamic loading capacity showed that the loading capacity of the modified activated alumina is 6.7 times compared with the unchanged activated alumina,which showed the modified activated aluminum had good adsorptive efficiency.
