中文摘要：

研究了磁性离子交换树脂和超滤膜组合工艺对微污染水源水的协同净化性能，并对膜污染进行了分析。结果表明，MIEX对有机物有很好的去处效果，主要去除对象为分子质量低于3k的腐殖质类有机物。MIEX＋UF组合工艺对SUVA、c0D‰和DOc的去除率分别为71．61％、60．34％和51．46％，出水浊度维持在0．1NTU以下。三维荧光光谱显示，原水中的有机物主要为陆生腐殖质类物质，组合工艺对其有很好的去除效果。膜污染分析表明，MIEX预处理虽然对uF进水中的有机物具有很好的去除效率，但却不能有效减缓uF膜污染，运行过程中膜污染阻力仍然在膜过滤总阻力构成申占最大比例（46．75％）。因此，采取措施减缓膜污染是进一步提高该组合工艺效能的关键

英文摘要：

The combined purification performance of micro-polluted sotlrce water by magnetic ion exchange resin （MIEX） and ultrafiltratiou （UF） combined process was studied in this paper, and the effect of membrane fouling control was also analyzed. The experimental results showed that good removal ability for organic pollutant can be achieved by MIEX treatment, and the main removal part was the humic organics with molecular weight of less than 3 k. The removal efficiency of SUVA, CODMn and DOC were 71.61%, 60.34%, 51.46% respectively after treatment by the combined process of MIEX＋UF, and the effluent turbidity was maintained at 0.1 NTU. Three-dimensional fluorescence spectrum analysis showed that the main organics in the raw water was the humic substances formed by land organisms, and the combined process has a good removal effect for this kind of substance, Although the MIEX pretreatment has good removal efficiency for organics, it can hardly alleviate the membrane fouling. And the resistance analysis suggested the membrane fouling resistance still accounted for the largest proportion （46.75%） of the total resistance. Therefore, it is very important to take measures to alleviate the membrane fouling in order to increase the efficiency of the combined process.
