介绍了焦化酚氰废水处理的工艺流程,对酚氰废水生化处理后氨氮浓度较高的问题进行了分析,并采取了改进措施,改进后氨氮浓度达到了设计要求。

Abstract:

The process of phenol-cynaide-containing waste water treatment in coking plants is introduced.The reasons for the high ammonia nitrogen concentration in waste water after bio-chemical treatment of phenol-cynaide-containing waste water are analyzed.Based on the analysis result,improvement measures are taken,after which the ammonia nitrogen concentration meets the design requirement.
