The slow flux decline was mainly caused by neutral hydrophilic fraction of organics with MW between 1 000~10 000, which plugs membrane pore.
相对分子质量在1 000~10 000的中性亲水性有机物，主要通过堵塞膜孔而造成膜通量缓慢下降。
In general the nitrobenzene flux in all cross sections is more and more weak, but the attenuation trend is gradually slow down.
总体上随硝基污染物污染团的下移各断面硝基污染物通量呈减弱趋势，但是衰减趋势逐渐缓慢。
As the filtration flux of the ordinary cross flow membrane filtration is very slow, the cross flow membrane filtration with electrastatic field is studied.
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。
