摘要：

为了提高PVDF中空纤维膜在处理含油废水过程中的亲水性能、抗压实性能和抗污染性能,实验以介孔Al₂O₃为无机添加粒子,采用溶液纺丝法制备出介孔Al₂O₃/PVDF复合中空纤维膜。通过扫描电子显微镜和傅里叶红外光谱观察介孔Al₂O₃/PVDF复合中空纤维膜的形貌和成分,结果证明介孔Al₂O₃成功地添加到PVDF中空纤维膜中。通过接触角,纯水和含油废水通量的测试,结果表明介孔Al₂O₃的添加改善了PVDF膜的亲水性能、抗压实性能和抗污染性能。

Abstract:

In order to improve the hydrophilic performance,anti-compaction performance and anti-fouling performance in the process of treating oil-bearing wastewater,mesoporous Al₂O₃ has been used as inorganic additive particles,and solvent spinning method has been used for the preparation of mesoporous Al₂O₃/PVDF composite hollow fiber membrane. The morphology and components of mesoporous Al₂O₃/PVDF composite hollow fiber membrane are observed with SEM and FT-IR. It is demonstrated that mesoporous Al₂O₃ can successfully be added into PVDF membrane. Through contact angles and the tests of the flux of pure water and oil-bearing wastewater,it is found that the addition of mesoporous Al₂O₃ has improved the hydrophilic property,anti-compaction property and anti-fouling property of the PVDF hollow fiber membrane.

Key words: PVDF, mesoporous Al₂O₃, hollow fiber membrane
