| 中文摘要: |
| 介绍了一种新的含油污水的油水分离方法，采取的主要措施是使用一种特殊设计的多孔材料，该多孔材料经过表面化学处理使其表面结构具有亲油的特性。当油水混合物流经该多孔材料时，其中细小的油滴被该材料粘住，而水则从该材料的多孔结构中流过。当不断聚集的细小油滴聚合成较大的油滴时，其斯托克斯力大于表面粘力。该油滴就受斯托克斯力的驱动，脱离粘住油滴的多孔材料向上浮升。 |
| 英文摘要: |
| A new technique for oil-water separation is presented, which is applied to oily wastewater treatment. A kind of specially manufactured porous material is used, the surface of which has the property of oil adhesion due to a chemical treatment. When an oil-water mixture flows through the porous material, fine oil droplets will adhere to the material, whereas water will pass through the porous structure. The adhering oil droplets gather together and a relatively large oil drop is gradually formed. When the buoyant force acting on the oil drop becomes larger than the adhesion, it will buoy up and separate itself from the porous material. |
