摘　　要：采用超滤膜技术处理含铬、铜实验室废液，探讨了pH对废液处理效果的影响。结果表明，pH对铬、铜的去除率影响较大。在pH=9．9时，超滤膜对铬、铜离子去除率最高，分别为96．2％和99．2％，利用超滤膜处理含铬、铜废液是可行的。The chromium and copper wastewater in laboratories was treated by ultrafiltration membrane. The effect of different pH values on removal ratio was examined. The result shows that the removal ratios of chromium and copper were affected by pH values remarkably. The further experiment shows that removal ratios are maximal （96.2% for chromium and 99.2% for copper respectively） when the pH value is about 9.9. It is feasible to treat chromium and copper wastewater by ultrafiltration membrane.
