【摘要】 采用乳状液膜法处理造纸黑液，研究了各种因素对ＣＯＤ去除率的影响实验结果表明，每１００ｍＬ煤油中表面活性剂为３ｇ，载体为２ｍＬ，乳水比Ｒｅｗ＝１∶１０，油内比Ｒｏｉ＝１∶１和搅拌速度ｎ＝３００ｒ／ｍｉｎ时，黑液中ＣＯＤ去除率为９８％以上，而且油相重复使用１２次时，ＣＯＤ的去除率基本不变更多还原

【Abstract】 Emulsion liquid membrane was used in treating paper mill black liquor and the factors affecting on removal ratio were studied.The result shows that the removal ratio of COD can be over 98% when the concentration of surfactant is 3*!g/100*!mL kerosene,the concentration of carrier is 2*!mL/100*!mL kerosene,the ratio of emulsion to water is 1∶10,the ratio of oil phase to internal phase is 1∶1 and the stirring speed is 300*!r/min.The effluent can accord with the standard. The removal ratio of COD is almost the same after 12 times reuse of the oil phase.更多还原
