摘要/Abstract

摘要：

不锈钢中空纤维膜基膜孔径大，直接涂覆分离层容易产生表面缺陷。在二氧化钛悬浮液中加入聚乙烯醇作为黏结剂，通过真空辅助抽滤法在不锈钢中空纤维基膜表面形成一层均匀的分离层。通过高温烧结得到了TiO₂/不锈钢中空纤维复合膜，考察了烧结温度对于TiO₂/不锈钢中空纤维复合膜表面分离层形貌和结构的影响。不同烧结温度时，TiO₂/不锈钢中空纤维复合膜的表面形貌有所差异；随着烧结温度的升高，不锈钢复合膜的孔径和纯水通量均先升高再下降。当烧结温度为500℃时，表面涂层均匀，孔径分布集中，水通量较高。最后，以SPT-500膜测试了水包油乳液分离效果，分离效率达到99%以上，且具有良好的抗污染性能。

Abstract:

Stainless steel hollow fiber membrane has large pore diameter, and the direct coating of the separation layer is liable to cause surface defects. In this paper, polyvinyl alcohol (PVA) is added to the suspension of titanium dioxide as binder, and a uniform separation layer is formed on the surface of stainless steel hollow fiber membrane by vacuum assisted method. TiO₂/stainless steel hollow fiber composite membrane was obtained by sintering at high temperature. The influence of sintering temperature on the morphology and structure of the surface separation layer was studied. The surface morphology of TiO₂/stainless steel hollow fiber composite membranes was different at different sintering temperatures. The pore size and pure water flux of the composite membranes increased first and then decreased with the increase of sintering temperature. It was found that the surface coating was uniform, the pore size distribution was narrow and the water flux was higher when the sintering temperature was 500℃. Finally, SPT-500 was used to separate oil-water emulsion. The separation efficiency was over 99% and it has a good anti-fouling performance.

Key words: stainless steel hollow fiber membrane, titanium dioxide particle, pyrolysis, polyvinyl alcohol, oil-water emulsion separation
