| 摘 要： | 探讨了Ｎ２５３－煤油－Ｈ２ＳＯ４－ＮａＯＨ化学萃取－反萃取体系提取浓缩Ｊ酸废母液中间体的工艺特性，试验结果表明，通过萃取工艺，Ｊ酸废液中的ＣＯＤｃｒ去除率可达９５％，萃余液ＣＯＤｃｒ在５００￣２０００ｍｇ／Ｌ之间，色度去除率可达９５％，该工艺可使废母液中的回收物浓缩５－１０倍，萃取剂可以循环使用而不改变性质，损失较少。

| Abstract: | J acid waste liquors is a high concentration organic waste water.In this research N 235 was used as extratant to extract useful substance from the J acid waste liquors. The tests indicated that more than 95% of CODc r in J acid waste liquor can be removed and CODc r in the remained liquors can be dropped to 500-2000 mg/L.95% of colourity can be removed from the waste liqours. By back extraction tests,extracted organic from waste liquors can be concentrated 5 to 10 times. In the process the extractant could be recycled for that its properties don't vary and it's lost is little. By recovery tests, the concentrated solution could be back to the appropriate section of the producing process directly to recovery useful substance, which will have no detrimental effects on the comprehensive indexes controlled in producing. |
