| 摘 要： | 针对焦化废水中氨氮对后续生物处理严重冲击的问题,利用实际废水作为研究对象,在试验规模的反应器中研究了废水温度、气液比、吹脱时间和pH值等参数对氨氮吹脱去除率的影响。利用所建立的优化操作条件在70m3/h规模的实际焦化废水处理工程实践中,对氨氮的处理效率稳定在68%~85%。对后续生物处理过程基本不构成影响。

| Abstract: | Aiming at the severe impact on the sequent biotreatment with ammonia nitrogen in coke plant wastewater,the influencing factors on the removal rate of ammonia nitrogen including the temperature of the wastewater,the air/liquid ratio,the stripping time and the predictive pH on the remove rate of ammonia nitrogen were investigated in the bench-scale reactor.The results showed that when treating the coke plant wastewater with the optimal operational conditions,under the wastewater scale of 70 m3/h,the removal rate of ammonia nitrogen reached 68%～85%,and there was basically no influence on the process of sequent biotreatment. |
