摘　　要：酒钢焦化酚氰废水系统生化单元采用的是一级曝气加两级AO的生化系统。自2020年6月份酚氰废水系统投运,生化单元效率较低,造成后续物化单元药剂添加量过多,导致废水运行成本居高不下。经过两年的探索、实验,发现生化单元中各水池溶解氧、pH、温度对于废水中COD和氨氮的去除率有很大的影响,本文通过对溶解氧、pH、温度调整控制,找出了最佳的控制范围,可有效提高生化效率,为今后的生化单元调节积累了宝贵经验。The biochemical unit of phenol cyanide wastewater system in JISCO adopts the one-stage aeration and two-stages AO biochemical system.Since June 2020,phenol cyanogen wastewater system was put into operation,the biochemical unit efficiency is low,causing excessive addition reagent of subsequent physical and chemical unit,resulting in high wastewater operating costs.After two years of exploration and experimentation,it was found that dissolved oxygen,pH,and temperature in each pool of the biochemical unit have a significant impact on the removal rate of COD and ammonia nitrogen in wastewater.The paper identified the optimal control range by adjusting and controlling dissolved oxygen,pH,and temperature,which can effectively improve biochemical efficiency and accumulate valuable experience for future biochemical unit regulation.
