摘要(Abstract)：

重金属废水的处理在环境保护和重金属资源综合利用方面都受到广泛的关注。采用中空纤维支撑液膜技术,用CuSO4水溶液模拟工业含Cu(II)废水,二(2-乙基己基)磷酸(D2EHPA)/煤油为液膜相,盐酸为接受相,研究了液膜相组成、两相流速、流动方式等因素对中空纤维支撑液膜过程传质性能的影响。结果表明,料液相在管程流动时的传质通量大于料液相在壳程流动时的传质通量,传质通量随着管、壳程两相流速的增大及液膜相中载体浓度的增加而增大。模拟实验结果表明,中空纤维支撑液膜技术可同时实现废水中Cu(II)的去除与浓缩,处理效果好。废水中Cu(II)的去除率达97%以上,富集液中Cu(II)浓缩倍数达5倍以上。
