摘　　要：目的:本实验采用微滤法对丁香挥发油含油水体进行油水分离,达到富集丁香挥发油的目的。方法:以丁香含油水体为分离对象,以通量和COD截留率为指标,来优化膜材质和压力、膜面转速、温度等操作条件。结果:应用QWLM亲水微滤膜,在压力为0.06 MPa,温度为60℃,搅拌速度150 r.min-1条件下油水分离效果最佳。结论:微滤法用于丁香挥发油含油水体的油水分离,富集丁香挥发油具有可行性。Objective： To separate essential oil of Caryophyllix flos from oil-in-water emulsion,and to enrich the essential oil by microfiltration（MF）.Method： Using membrane flux and removal rate of COD as the indicatrixes,the membrane material as well as the operating conditions containing pressure,surface speed,temperature were optimized.Result： The results showed that QWLM membrane of hydrophilic is the proper membrane,and the best operating conditions was at 0.06 MPa,60 ℃,and 150 r·min-1 stir speed.Conclusion： It can be concluded that MF is a reasonable way to enrich essential oil of C.flox.
