摘要
研究流化床离子交换从含铀废水中吸附铀的过程。结果表明,在吸附溶液pH=3左右,铀浓度15～36mg/L,塔有效吸附段高6.65m的条件下,采用30～40m/h的空塔线速度,流量比400～600,用新旧树脂吸附都可使吸附尾液中的铀浓度≤0.1mg/L。
The process of Uranium absorption from mine wastewater containing Uranium with fluidized bed ion exchange column is investigated. The experimental results show that the less than 0. 1mg/L Uranium concentration in absorbed raffinate can be achieved with the new or used resin under the condition of adsorption solution pH about 3, Uraniumconcentration 15-36mg/L and the tower effective adsorption section 6.65m high, 30- 40m/h void tower link speed, 400-600 flux ratio.
