摘    要:采用乳化液膜分离技术处理造纸工业废水,研究了表面活性剂用量、乳水比(Rew)、油内比(Roi)、载体用量、搅拌速率及处理时间等对COD去除率和透光度的影响,得出了最佳实验条件:表面活性剂3%,膜增强剂(液体石蜡) 5%,载体(正三辛胺)4%,乳水比1:10,油内比1:1,制乳时搅拌速度2 300 r.min-1,处理时搅拌速度200r·min-1,处理时间为15min。在此条件下,造纸废水的COD去除率可达85%以上,色度去除率达98%以上.具有较大的推广应用价值。

关 键 词:乳化液膜  造纸工业废水  COD去除率

Abstract:The application progress of liquid membrane separation technology on papermaking industry wastewater treatment is discussed; The conditions of preparing steady membranes and the effects of different experimental factors(such as surfactant concentration, the inner solution, membrane strengthening reagent, stirring speed, carrier dosage, stirring time,Rew Roi ) are studied. The optimal experimental condition is obtained. The results show: the papermaking industry wastewater is treated by liquid membrane technology, its COD removal rate is about 85%, color removal rate can reach 98%, so it has a good efficient and the oil phase can be reused. Papermaking wastewater treatment by emulsion membrane has both economic and environment advantages.
Keywords:emulsion membrane  papermaking wastewater  COD removal rate
