以制药厂主要成分为苯胺盐酸盐的实际工艺废水为研究对象，采用中和分层-水相萃取-蒸馏回收联合工艺对该废水进行处理。结果表明，甲苯及二氯甲烷具有良好的萃取效果且可重复使用，经系列工艺处理后，分离出的苯胺可进行套用或回收，实现资源的再利用；处理后废水中苯胺降至200 mg/L以下，COD降至3 000 mg/L以下。

The actual process wastewater in the pharmaceutical factory, whose main component is aniline hydrochloride, is treated by a combined process of neutralization and stratification-aqueous phase extraction-distillation and recovery.It is indicated that toluene and dichloromethane have good extraction effect and can be reused.After the treatment by the process, aniline separated out can be reused or recycled.The contents of aniline and COD in the treated wastewater are reduced to below 200 mg·L^-1 and 3 000 mg·L^-1, respectively, both meeting the requirements of the enterprise's technical objectives and entering the subsequent desalination section.
