摘要(Abstract)：

为了提高聚偏氟乙烯(PVDF)管式膜的亲油性,以PVDF管式膜作为基膜,采用不同处理剂对其进行后处理,得到亲油管式膜;研究不同处理工艺条件、不同处理剂对膜透油通量的影响以及处理前后膜结构和性能的变化情况;采用电子显微镜(SEM)、原子力显微镜(AFM)、Zeta电位测量仪对改性前后PVDF管式膜进行了表征。结果表明:改性后PVDF管式膜的接触角明显增加,粗糙度略有增大;处理剂1、处理剂2和处理剂3都能使基膜转化为亲油膜,在处理剂2处理1 h、晾干1 d的条件下,膜油通量可达到330.8 L/(m2·h),表明改性后PVDF管式膜的亲油性有了很大的提高;用改性PVDF管式膜对废冷镦油进行了过滤,对亲油管式膜过滤后的废冷镦油的黏度、浊度、密度和含水率进行测试结果表明过滤后的废冷镦油黏度下降,浊度整体小于0,密度和含水率也有了一定的改善,表明改性PVDF管式膜对废冷镦油的处理效果良好。
