摘　　要：综述了应用离子液体作为溶剂的萃取工艺在治理冶金电镀废水、油田采出水、印染废水和化工制药废水中的应用,其可以高效地、高选择性地除去工业废水中的金属离子、有机染料、有机酚类和其他芳香族化合物,使水体净化。与使用传统有机溶剂的萃取工艺相比较,该萃取工艺具有萃取效率高、萃取过程中不产生二次污染和可回收利用溶剂等特点,因此该工艺有望被广泛地应用于工业废水的治理。The application of ionic liquid as the extracting solvent in sewage treatment was reviewed according to the sources of the sewage such as metallurgical and electroplating wastewater, oilfield produced water, printing and dyeing waste water and chemical pharmaceutical waste water. Typical water pollutants such as metal ions, organic dyes, organic phenolic and other aromatic compounds can be seperated from industrial sewage efficienctly and selectively by ionic liquid extraction technology. In comparison with traditional organic solvent extraction process, ionic liquid extraction process has many advantages such as higher extraction efficiency, zero secondray pollution and easy solvent recycle. For these reasons, the ionic liquid extraction technology will be applied in sewage treatment widely.
