加压生物氧化法处理乙胺废水

Research on the Treatmemt of Ethylamine Wastewater by Pressurized Bio oxidation Process

用加压生物氧化实验设备处理乙基胺及异丙胺生产的工艺废水，进水ＣＯＤ１０００—３０００ｍｇ／Ｌ，设备ＣＯＤ容积负荷Ｆｖ为４—２３ｋｇ／（ｍ３·ｄ），经过２—６ｈＣＯＤ去除率为８５％—９５％，出水ＣＯＤ＜１５０ｍｇ／Ｌ。

The pressurized bio oxidation experiment equipment is used to treatment waste water in the production process of ethylamine and isopropylamine.The concentration of COD in the influent is 1000—3000mg/L and the COD volume load of the equipment is 4—23kg/(m 3·d).Through treatment for about 2—6h,the removal rate is 85%—95% and the conceneration of COD in the effluent is less than 150mg/L which reaches the national drainage standards.
