【Abstract】 The interaction between gelatin and polyacrylonitrile or polysulfone membranes and the effects of operating parameters on the performance of the membranes were studied. The results show that the polyacrylonitrile hollow fiber membrane is useful for the recovery of waste colour developing solution. The hollow fiber ultrafiltration equipment has several adevan-tages, such as the better flow properties, the lower investment and maintenance cost, the high efficiency and the shorter period for recovering investment and so on.更多还原
