摘　　要：本文提出了稀型乳状液膜分离方法的新概念。作者用稀型乳状液分离技术,在φ500mm×3000mm的机械搅拌柱中,处理粘胶纤维的酸性含锌废水,经一次接触后,废水中锌含量可从500ppm降至5ppm,达到国家允许排放的要求。过程中无二次污染;过程中回收锌的价值大于治理过程中所消耗的一切费用的价值。A new concept of the dilute emulsion liquid membranes was advanced in this paper. Treating zinc-containing acidic waste water of viscose staple fibre by the dilute emulsion liquid membranes in a stirring column of φ500mm × 3000mm, the concentration of Zn^(2+) in waste water after one step treatment reduced from 500ppm to less than 5ppm, which is less than the discharge standard. In this process, there is not second pollution. All operation cost and cost of reagents are less than the profit of the recovered ZnSO_4.
