摘要：

采用正辛醇为载体的乳化液膜体系进行了苯酚和邻甲酚废水的脱酚试验，研究了乳化液中的载体、表面活性剂、内相试剂浓度和油水比对脱酚效果的影响。在传质条件方面，考察了传质搅拌速率、传质时间、乳水比和初始酚含量等因素的影响。结果表明，在乳化液中正辛醇体积分数0.4%、油水比1∶1、液体石蜡体积分数5%、表面活性剂T154 体积分数6%、内相NaOH溶液浓度为0.6 mol/L、乳水比1∶6的实验条件下，经过一级乳化液膜分离过程，可快速脱除苯酚和邻甲酚，脱除率达到99%以上。

Abstract:

Phenol removal from wastewater containing phenol and o-cresol by emulsion liquid membrane with normal octanol as carrier was investugated by varying oil/water ratio，carrier concentration，surfactant and internal phase reagent. Mass transfer conditions including stirring speed，mass transfer time，emulsion/water ratio and initial phenol content were also examined. Removal rate of higher than 99% was achieved through one stage of emulsion liquid membrane separation in a short time at conditions as：the concentrations of octanol，liquid wax，surfactant T154，NaOH in inner phase were 0.4%，5%，6% and 0.6 mol/L respectively，while the oil/water ratio was 1∶1 and emulsion/water ratio was 1∶6.
