摘　　要：研究用MAE(membrane-assistedelectrolysis)单阳膜技术控制造纸黑液的污染,探讨了这种膜技术从造纸黑液中回收氢氧化钠等有用化学品的途径;黑液中大量存在的硅,对离子交换膜可能产生的影响;黑液污染控制的可行性和控制的程度.研究表明:MAE单阳膜技术不但能回收有用的化学品,还可将黑液的CODCr值从112000mg/L处置到2000mg/L左右,具有明显的控制效果.The application of single-positive membrane（SPM） technique in the treatment of paper-making black liquor （PMBL） pollution was studied. The questions, the way for recovering such chemicals as NaOH from PMBL, the potential effect of a large amount of silicon existing in PMBL on ion-exchange membrane performance,and the possibility and degree of PMBL pollution controlling, were investigated. The results show that not only SPM technique can recover chemicals from PMBL, but also it can reduce efficiently the COD values of PMBL from 112 000 mg/L to 2 000 mg/L.
