| 摘 要： | 该文通过混凝+沉淀+超滤联用工艺中试试验,探讨中试规模超滤膜对于原水中有机物亲水/疏水性组分、不同分子量的分布以及有机物属性的去除规律.试验得出,极性亲水性组分和中性亲水性组分经膜过滤DOC浓度下降明显,最容易被膜截留,造成膜通量下降.同时,在混凝沉淀阶段,可以有效去除6 000～1 000 Daltons范围的较大分...

| Abstract: | Through the pilot-scale experiment of coagulation-sedimentation-UF membrane,membrane's operation situation in treating water in a river was investigated.The paper analyzed the characteristics of the raw water,including the hydrophilic / hydrophobic properties,molecular weight(MW) distribution,and 3D-EEM analyse.From the results of MW distribution,it could be concluded that: the coagulation-sedimentation section removed some organic matters of bigger MW of 6 000 to 1 000 Daltons;moreover,the UF membrane coul... |
