摘要
针对普通十字流膜滤中膜滤速率低下问题，试验研究了附加电场下的十字流膜滤．实验观察了电泳迁移作用使膜面沉积层消失的过程及膜滤中的电渗流，并从理论上分析了附加电场使膜滤速率大幅度提高的机理．
As the filtration flux of the ordinary cross flow membrane filtration is very slow, the cross flow membrane filtration with electrastatic field is studied. The disapearance of the deposit on the membrane surface as a result of eletrophoresis and electroosmosis during the membrane filtration was observed. The reason why the membrane filtration flux with electrostatic field increases sharply is also analysed theoretically.
