【摘要】 主要采用"煤气吹脱解吸法"对焦化厂含氨废水中氨氮进行吹脱解吸的优选实验研究。实验的最佳反应条件为:T=80℃,pH=10.2,Q=5L/min(气液比为1500∶1),t=120min,C=0~25 mg/L。处理后废氨水中氨氮脱除率达到96%以上,取得了满意的效果,同时氰、酚和COD也都不同程度地被脱除。经生化处理后,氨氮含量可达到国家排放标准。更多还原

【Abstract】 This text adopted "gas stripping and adsorption process" to do experiments on removing the ammonia nitrogen from waste ammonia water in the coking plant.The best condition of the experiment is: T=80℃,pH= 10.2,Q=5L/min(air-liquid ratio is 1500:1),t=120min,C=0～25 L/min.The removing rate of the ammonia nitrogen in the treated ammonia water is over 96%,which obtains a satisfied result,simultaneously the cyanide,the phenol and the COD are removed in some degree.After bio-treatment,the target of NH3-N can meet the national discharge standard.更多还原
