| 摘 要： | 研究了FeO（OH）动态膜的膜通量衰减与FeO（OH）胶粒的凝并关系。以阴离子表面活性剂对FeO（OH）胶粒表面修饰并将其形成的动态膜与未修饰时比较，结果显示：成膜时间从6～8h减少至1～2h；在同样成膜压力（0.11MPa）下，膜通量增大13．2％，在最大值条件（0．24MPa和0．11MPa）下，膜通量增大24．1％；用该膜处理印染厂二沉池排水，脱色率高达98．5%，膜通量增加40％-150％，运行周期提高2～3倍。

| Abstract: | The relationship between the flux and agglomeration of FeO(OH) colloid was investigated. The FeO(OH) colloid was modified with anionic surfactant to form a dynamic membrane. Comparing with that formed by the unmodified colloid, the results showed that the time of forming the membrane was reduced from 6~8 h to 1~2 h, the flux was increased by 13.2% at 0.11MPa and by 24.1% in maximum values condition(at 0.24 and 0.11 MPa respectively ). The color removal was up to 98.5%, the flux was increased by 40%~150% and the run period was increased by 2~3 times when using this dynamic membrane in treating the title wastewater. |
