摘　　要：分别选取一种内压式和一种外压式中空纤维膜超滤组件,从超滤膜材质、运行参数和出水水质等方面对这2种组件在海水淡化反渗透预处理中的应用做了比较。结果表明:由于超滤膜的材料不同,使得2种组件运行工艺有较大差异:内压式组件在跨膜压差和膜通量方面要好于外压式组件,而2种组件出水水质在同一水平上。在进水浊度小于20NTU时,内压式膜组件更适合作为反渗透的预处理工艺。An inside-out and an outside-in hollow fibre membrane ultrafitraion module were chosen, the application effect of them in pre-treatment of sea water reverse osmosis were compared from the materials of UF membrane, operation parameter, effluents quality and some other aspects. The results show that： because the materials of the UF membranes are different, the operation craft of these two modules has big difference： the transmembranous pressure （TMP） and the membrane flux of the inside-out UF membrane module are better than that of the outside-in UF membrane module. However, the quality of the effluents from these two modules are on the same level. When the turbidity of the influent water is below 20 NTU, inside-out UF membrane module is more fit for the pre-treatment of reverse osmosis.
