摘　　要：简要叙述了聚氨基葡糖超滤膜的制备方法。着重研究了其在印染废水处理中的应用，结果表明用聚氨基葡糖超滤膜处理实际印染废水，其ＣＯＤ去除率可达８０％左右，脱色率超过９５％。A chitosan ultrafiltrating membrane was prepared by phase reverse technique involving coagulation of the chitosan sloution in NaOH solution. The membrane prepared by the technology has excellent separation performance for such an acid red B dye which was hard of treatment by common coagulation technology. The decolorization efficiency of acid red B aqueous solution achieved 91%～98%. To real printing and dyeing waste water, the decolorization efficiency was above 95% and the removal of COD was 88%. Its effect was better than that of tranditional treatment methods.
