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6～8 h减少至1～2 h;在同样成膜压力(0.11MPa)下,膜通量增大13.2%,在最大值条件(0.24 MPa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.
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.
