摘要
以磷酸三丁酯(TBP)为载体、煤油为膜溶剂、NaOH水溶液为内水相,采用乳状液膜法处理兰炭废水。实验结果表明:当TBP体积分数为4%、表面活性剂质量分数为4%、内水相NaOH质量分数为12%、油内比(乳状液的油相与内水相的体积比)为3∶2、乳水比为1∶5、萃取时间为15 min时,废水中的酚类(以苯酚计)去除率达到85%以上,COD去除率达83%以上。
The semi-coke production wastewater was treated by emulsion liquid membrane method using tributyl phosphate（TBP） as carrier,kerosene as membrane solvent,and NaOH solution as aqueous phase.The experimental results show that when the TBP volume fraction is 4%,the surfactant mass fraction is 4%,the mass concentration of NaOH in the internal phase is 12%,the volume ratio of oil to internal phase is 3∶2,the volume ratio of emulsion liquid to wastewater is 1∶5 and the extraction time is 15 min,the removal rats of phenols（calculated in phenol） and COD are above 85% and 83% respectively.
