摘　　要：采用非流动载体乳状液膜法处理高碱性含氨和苯胺类化合物的染化废水.考察了表面活性剂种类和浓度、内水相硫酸浓度、外水相pH等对迁移率的影响.实验表明,当采用2%LMA-1煤油溶液为油膜相和2mol/L硫酸溶液为内水相时,经过二级液膜提取分离,含有5000mg/L氨和600mg/L苯胺类化合物的高碱性染化废水中氨和苯胺类物质的迁移率可达98%以上.An emulsion liquid membrane process is developed to treat anilines dyeing wastewater.The effects of surfactants categories and concentration,sulfuric acid concentration in the internal aqueous phase,the pH in the external aqueous phase,and φew on the transports of ammonia and anilines are examined.The experimental results show that 98% of ammonia and anilines is removed from wastewater containing 5 000 mg/L ammonia and 600 mg/L anilines with two-step membrane process when the membrane phase consists of 2%LMA-1 and kerosene and the internal aqueous phase is 2 mol/L sulfuric acid solution.
