摘　　要：针对粘胶纤维厂排放的含锌废水，对乳状液膜的制备条件、乳状液与废水的混合分离工艺和交流高电压破乳器设计方法进行了较为详细的理论和实验研究。结果表明，在最佳操作条件下，经一级液膜分离，废水中锌离子浓度可降至５ｐｐｍ以下。The preparation for emulsion liquid membranes , the emulsion liquid membranes separation process and the design methods for A.C. high voltage electric demulsifier concerning with the recovery of zinc from wastewater of viscose industry have been studied by means of theory and experiments. The experimental results indicate that under the optimal operation condition, the zinc concentration in wastewater can be reduced to less than 5 ppm by one stage of emulsion liquid membranes separation.
