| 摘 要： | 采用离子交换和加入石灰的方法处理邻氨基苯甲酸生产废液，去除其中的Ｎａ＾＋和ＳＯ４＾２－，保留其中的ＮＨ４＾＋和邻硝基苯甲酸，处理后的废液回用于生产过程中，不仅消除了废液外排所产生的污染，还回收了ＮＨ４＾＋和ＯＮＡ，有较好的经济效益。

| Abstract: | The waste liquor from o-aminobenzoic acid production has been treated by ion exchangeand addition of lime to remove Na+ and SO2-4,and retain NH+4 and o-nitrobenzoic acid. The treated effluent was recycled to the production process. It not only eliminated the pollution caused bythe discharge of the waste liquor, but also recovered NH+4 and ownitrobenzoic acid, realizing a bet-ter economic benefit. |
