农药中间体氯化废水处理技术研究

RESEARCHES ON THE TREATMENT OF WASTEWATER CONTAINING CHLORIDE IN PESTICIDE INTERMEDIATE

甲胺磷生产过程中的氯化碱性废水（简称含磷废水）经回收甲醇后，该废水中含有高浓度的有机磷、ＣＯＤ和ＮａＣｌ，环境不允许未处理就排放。作者介绍了该废水的处理工艺技术以及在生产中应用结果，ＣＯＤ去除率达８０％，有机磷去除率达８５％。

The wastewater containing phosphor in pesticide parathion production can be discharged by biochemical treatment after multiple dilution, and the wastewater with alkality in methamidophos production after methylalchol recovery,which contains highly concentrated organophosphorus, COD and sodium chloride,has not been treated before, and polluted the environment. In this article, we give the treatment technique of the wastewater, and has been applied in the production. The ratio of COD removement reaches 80%,and of organophosphorus reaches 85%.We get good effect.
