| 摘 要： | 以造纸废水为研究对象,通过化学混凝、氧化等处理方法,使COD指标由原来的11 000 mg.L-1降至150 mg.L-1。使处理后的造纸废水可重新用于造纸制浆,对所产生的污泥,用甲基异丁基甲酮、乙醇和水的混合溶液进行提取,将其中的木质素进行回收,实现了造纸废水的资源化。

| Abstract: | Papermaking wastewater was chemically coagulated and oxidized.Its COD value was dropped from 11 000 mg·L-1 to 150 mg·L-1, and the water could be reused in pulping.With solution of methyl isobutyl ketone,alcohol and water,lignin was distilled from the remained sludge.By such treatments,papermaking wastewater is utilized as a resource. |
