| 摘 要： | 文中研究一种新型纳滤膜对大孔树脂再生废碱液的过滤纯化作用。工业废碱的碱含量为2％-3％，COD在5000-10000mg／L之间，透光度为10％以下。通过S-357纳滤膜，可回收用于树脂再生的稀碱液。稀碱液的碱含量为2％，COD在400mg／L以下，透光度接近100％。纳虑过滤过程通量稳定，简单的化学清洗可恢复通量。

| Abstract: | The purification of waste alkali solution, which came from the regeneration of macroporous resin, was studied in this paper. Eighty percent alkali can be recycled from waste alkali solution, which contain 2%-3% alkali and 5000-10000 mg/L COD. The transmittance increased from 10% to 100% after nano-filtration. The COD of reclaimed alkali was less than 400 mg/L. The flux of filtration was stable and reversable after simple chemical clean. |
