| 摘 要： | 合成出了适合于含油污水处理的憎水性离子液体，研究了离子液体对含油污水的处理条件。当离子液体与含油污水体积比为1∶5，pH值为5,处理15min后，水中油的去除率为95.6%，CODCr的去除率为93.5%，表明应用离子液体可以有效地去除油田采出水中的有机物。同时考察了再生离子液体对除油效果的影响，其五次平行实验的除油率达95.4%,CODCr去除率为93.2%，表明离子液体可以回收利用。在此基础上，分析了离子液体对含油污水处理的作用机理。

| Abstract: | The hydrophobic ionic liquid, \BMIM\]\BF6\] was synthesized, and the treatment conditions were investigated. When the extraction ratio is 1∶5, and pH=5, after 15min, the oil removal ratio is 95.6% and the CODCr removal is 93.5%. At the same time, the recovery of ionic liquids experiment was carried out. By the recovery ionic liquid, the oil and CODCr removal were 95.4%and 93.2% respectively, the results showed that ionic liquid can be regenerated and the effects are not reduced. The results indicate that the hydrophobic ionic liquids can remove the oil and organic compounds in the oilfield wastewater effectively. And the mechanism of ionic liquids was proposed. |
