摘　　要：探讨了超滤法处理浆纱废水中PVA的工艺。研究了膜的孔径、操作压力、温度、pH值和透水量等对处理效果的影响。结果表明,PVA回收率和COD去除率分别达到90％和85％～90％。This paper reported the technology of treating PVA from sizing wastewater with ultrafiltration process. The effects of pore diameter of membrane, processing pressure, temperation. pH and filterable flow on treatment efficiency were studied. The results showed that recovery rate of PVA and removal of CODcr were more than 90% and 85%～90%, respectively.
