摘　　要： 焦化尾水中小分子种类丰富,大分子有机物含量较少,但都含有大量苯环结构,难以降解,是造成尾水难以达标的主要成分。本文主要研究采用多段蒸馏强化蒸氨过程对COD的分离效果,并通过SBR法对中馏液与现有蒸氨工艺条件下的蒸氨废水的可生化性能进行对比,证明多段蒸馏对蒸氨过程的COD分离是有效的,并能提高焦化废水的可生化性能。 The coking tail water is rich in small and medium-sized molecules,but contains large amounts of organic compounds,but it contains many benzene rings,which is difficult to degrade. It is the main component of tail water which is difficult to reach the standard. In this paper,the separation effect of COD by multistage distillation and ammonia distillation process was studied.The biochemical performance of ammonia distillation wastewater was compared with the existing ammonia distillation process by SBR.
