摘要：

本文采用乳化液膜法去除焦化废水中的苯酚，建立了以磷酸三丁酯(TBP)为载体，Span-80为表面活性剂，煤油作膜溶剂及以NaOH溶液为内相的乳化液膜体系。首先采用红外光谱分析手段，测定TBP负载苯酚红外光谱图，通过相应官能团的波数位移变化，得出TBP与酚类物质属氢键缔合。其次通过液膜稳定性实验表明：当表面活性剂浓度为5%、油内比为1:1、制乳时间为30min、制乳转速为2000r/min时，可以得到较为稳定的乳化液膜；最后根据分离实验结果得出：当表面活性剂浓度为5%、搅拌速度为300r/min、油内比为1:1、NaOH溶液浓度为0.5mol/L、分离时间为30min、载体浓度为0.2mol/L、乳水比为1/3时，苯酚的迁移率可达到95%以上。

The emulsion liquid membrane method was used to remove phenol from coking wastewater. An emulsion liquid membrane system was established with tributyl phosphate (TBP) as the carrier, Span-80 as the surfactant, kerosene as the film solvent, and NaOH solution as the internal phase. First, the infrared spectrum analysis method was used to determine the infrared spectrum of TBP-supported phenol. Based on the change of the wave number shift of the corresponding functional group, it was concluded that TBP was hydrogen-bonded with phenols. Liquid film stability experiments show that when the surfactant concentration is 5%, the internal oil ratio is 1:1, the milking time is 30min, and the milking speed is 2000r/min, a more stable emulsion film can be obtained; separation experiment The results show that when the surfactant concentration is 5%, the stirring speed is 300r/min, the oil ratio is 1:1, the NaOH solution concentration is 0.5mol/L, the separation time is 30min, the carrier concentration is 0.2mol/L, the milk When the water ratio is 1/3, the mobility of phenol can reach more than 95%.
