• 中文摘要： 本文研究液-固流體化床中利用離子交換的方法將廢水中的銅和鎳離子去除。流體化床之內徑和高度分別為8.1和150公分。使用之廢水為硫酸銅/硫酸鎳溶液; 離子交換樹脂為Amberlite 200C。研究結果顯示流體化床出口流之銅和鎳離子的濃度隨著床內離子交換樹脂量或液體流速增加而降低,但隨著進口流中銅和鎳離子之濃度增加而增加。進口流之pH不影響銅和鎳離子之貫穿曲線。軸向分散模式結合「擬化學反應」模式可用以描述此一流體化床之多成分離子交換程序。本文亦比較流體化床離子交換和固定床離子交換之優劣。
• 英文摘要： Removal of Cu/sup +2/ and Ni/sup +2/ from wastewater by ion exchange in a liquid-solid fluidized bed is studied. The column diameter and height of the fluidized bed are 8.1 and 150cm, respectively. CuSO/sub 4//NiSO/sub 4/ solution is used as the synthetic wastewater and the resins used are Amberlite 200C. It is found that the effluent Cu/sup +2/ and Ni/sup +2/ concentrations of the fluidized bed decrease with an increase in the solids loading or liquid velocity. However, they increase as total concentration of Cu/sup +2/ and Ni/sup +2/ in the feed is increased. Moreover, the effect of the pH of the influent solution on the breakthrough curves of Cu/sup +2/ and Ni/sup +2/ is negligible. An axial dispersion model with the "analogy to chemical reaction" model are employed to satisfactorily describe the multicomponent ion exchange process in the fluidized bed. A comparison of the performance of ion exchange in the fluidized bed and the packed bed is also made in this study.
