| Abstract: | The charged nanofiltration membranes were prepared by ultraviolet irradiation modification with poly-acrylonitrile (PAN)membranes as the matrix. The factors which influence the behaviour of nanofiltration membranes were studied. And treatment of chemimechanical pulping effluent by using the prepared nanofiltration membranes was carried out. It was showed that the retention ratio of Na increased by 15 times,and the permeation flux reduced by 12 times,as the charged nanofiltration membrane was prepared with the matrix (PAN). |
