Abstract:

In the process of the advanced treatment of coking wastewater after biochemical processes with coagulation air floatation-BAF， and in order to improve the operational cycle and reduce the times of BAF backwashing， the suspended solids of raw water flowing into BAF must be effectively removed. Combined with practical engineering， the application of coagulation air floatation to the advanced treatment of coking wastewater after biochemical processes is introduced. And the amount of flocculant added is optimized. It provides reference for the advanced treatment of coking wastewater after biochemical processes.

Key words: coagulation air floatation, coking wastewater after biochemical processes, biological aerated filter

摘要：

在利用混凝气浮-曝气生物滤池深度处理焦化生化尾水的工艺中,为了提高曝气生物滤池的运行周期,减少反冲洗次数,必须有效地去除进入曝气生物滤池的原水悬浮物。作者结合实际工程介绍了混凝气浮在焦化生化尾水深度处理中的应用情况,优化了最佳加药量,为焦化生化尾水的深度处理提供参考。
