| 中文摘要: |
| 世界生态环境逐渐恶化，为保护生态环境，含油废水的无害化处理排放成为保护生态环境的必要做法。膜处理技术作为20世纪最具发展前景的污水处理技术之一，具备低能耗，分离效率高等特点。聚四氟乙烯薄膜（PTFE）膜由于其具有的极高化学稳定性、良好的力学性能、过滤速度高、使用寿命长等特点，被广泛应用于水处理领域。为此本文概述膜分离原理，结合膜本身特点和改性方法，重点对PTFE膜及其改性膜在含油废水中的应用进行综述，并探讨了PTFE膜在应用过程中亟待解决的问题，为PTFE膜及其改性膜在水处理中的应用提供技术和理论支持。 |

| World ecological environment worsening, to protect the ecological environment, the oily wastewater disposal emissions are necessary to protect the ecological environment. As one of the most promising wastewater treatment technologies in the 20th century, membrane treatment technology has the characteristics of low energy consumption and high separation efficiency. Polytetrafluoroethylene (PTFE) film is widely used in the field of water treatment due to its high chemical stability, good mechanical properties, high filtration rate, long service life and other characteristics. This paper outlines the principle of membrane separation, combining with the characteristics of the film itself and the modification methods, the key of PTFE membrane and their modified membrane application in the oily wastewater were reviewed, and discussed the problem to be solved in the process of application of PTFE membrane, providing technical and theoretical support for the application of PTFE membrane and its modified membrane in water treatment. |
