| 中文摘要: |
| 膜污染是聚偏氟乙烯膜在污水处理工程应用的主要障碍，膜亲水改性是改善膜污染的主要方法。本文根据改性方法的异同，按照表面涂覆、表面接枝、共混改性、共聚改性等方法进行了综述。通过分析不同改性方法对PVDF亲水效果、渗透能力、抗污能力及长期有效性等方面的影响，讨论了各种改性方法的优缺点，为PVDF膜处理的应用提供技术和理论支持。 |
| 英文摘要: |
| Membrane fouling constitutes a bottleneck limiting the efficient and wide application of polyvinylidene fluoride (PVDF) membrane. One of the main way to improve the antifouling performance of PVDF membrane is surface hydrophilic modification. This paper reviews surface coating, surface grafting, blending modification, copolymerization modification in different modification methods. By analyzing the effects of different modification methods on hydrophilic effect, permeability, antifouling ability and long term effectiveness of PVDF, the advantages and disadvantages of various modification methods were discussed, providing technical and theoretical support for the application of PVDF membrane treatment. |
