摘要
阐述了脱氨氮的方法,重点介绍了吹脱法处理含氨氮的AC废水,经过试验得到吹脱的较佳条件:pH11,温度70℃,气液比1000,吹脱时间2h。在此条件下氨氮脱除率为97%以上。吹脱后的废水可进行生化处理。
Removal methods of ammonia and nitrogen by blow-off are introduced with emphasis on treatment of AC wastewater which contains ammonia and nitrogen. Through the tests of blow-off, we can get better conditions: pH 11, temperature 70℃, ratio of gas and liquid 1000,blow-off time 2 h. At these conditions, removal of ammonia and nitrogen is over 97%. Wastewater after blow-off can be treated biochemically.
