聚醚酮膜超滤深度处理造纸过程水的试验

Experiment Study on Ultra-Filter Treatment to Process-Water of Papermaking in Polyether-Ketone(PEK)

对聚醚酮膜超滤法深度处理造纸过程水进行了试验研究。结果表明,超滤操作条件为:压力0.25MPa,水温30℃,搅拌速度60r·min-1时,聚醚酮超滤膜(PEK-20000)超滤出水的浊度为0.153NTU,UV280为1.17,去除率分别为96.8%和63.4%,满足造纸过程水回用对悬浮物和胶体物质的要求,且膜通量较高,为92.3L·(m2·h)-1。

Ultra-filtration process parameter of process-water of papermaking was studied. The results showed that the optimized process-parameter, turbidity removal was up to 98.6%, UV280 reduced up to 63.4%, membrane flux was up to 92.3 L-（m2.h）-1.
