中文摘要：

研究了以磷酸三丁酯为载体的Span-80/甲苯/NaOH乳状液膜体系的制备及稳定性.通过乳液液膜法处理兰炭含酚废水，探讨了表面活性剂和载体用量、NaOH浓度、乳水比、乳水接触时间、油水比等对除酚率的影响.结果表明，在表面活性剂的体积分数为4%，膜助剂体积分数为3%，载体的体积分数为3%，内水相NaOH浓度为3%，乳水比1：3，乳水接触时间10 min，油水比1.2：1，废水pH值为5左右的条件下，除酚率达到96%以上.

英文摘要：

This study investigated the preparation and stability of Span-80/toluene/NaOH emulsion liquid membrane system in tributyl phosphate. In the investigation of phenol removal from semi-coke wastewater by the emulsion liquid membrane, the influence of different factors such as surfactant and carrier amount, NaOH concentration, emulsion/water ratio, mixing time and oil/water ratio on the extraction rate of phenol were examined. The experimental results show that extraction rate of phenol was more than 96% when the concentrations of tributyl phosphate, liquid wax, surfactant Span-80 and NaOH in inner phase were 3%,3%,4%,3%, the emulsion/water ratio 1：3, mixing time 10 min, the oil/water ratio 1.2：1 and the pH of external aqueous phas about 5.
