提铝钠铁后赤泥残渣的除氟性能
|
摘要
赤泥近年来被广泛研究作为废水处理的吸附材料。采用无氧高温还原—浸出—磁选工艺回收赤泥中铁、铝及钠后的残渣仍含适量的活性物质,以该残渣为吸附剂,研究其对高氟水的除氟性能。以配制含氟25mg/L的水溶液为处理对象,获得的最适宜除氟条件为:溶液初始pH=5、残渣添加量25g/L、温度40℃、吸附时间30min,该条件下除氟效率到达72.19%。
Red mud has been widely studied as an adsorbent for wastewater treatment due to its containing active components in recent years.The residues,obtained from red mud after recovering aluminum,sodium and iron by reductive sintering-leaching-magnetic separation,still contain a certain amount of active components.Defluorination performance of residue for synthetic wastewater bearing 25 mg/L fluoride was investigated.Defluorination efficiency is 72.19% under the optimum conditions including initial pH value of 5,residue dosage of 15 g/L,temperature of 40℃,and adsorbing time of 30 min.
