摘要
本文主要研究了不同工艺运行参数对一体化AmOn工艺处理城市污水效果的影响,试验表明,AmOn工艺适宜的水力停留时间为8.5h,这使得工艺整体的处理效率处于较高水平;当水温在20℃以上时,AmOn工艺适宜的污泥龄为10d;好氧区DO浓度处于2.5～4.5mg/L之间时,AmOn工艺的整体脱氮除磷效果较好。
The influence of different operating parameter on AmOn integrated process is discussed in this paper. The results show that the suitable HRT of integrated process was 8.5h, which had not only better removal effect on wastewater treatment but also high integral efficiency in the view of whole process. The suitable SRT of integrated AmOo process was I 0 days when the water temperature was over 20℃. When the DO concentration was in range of 2.5 -4.5mg/L, integrated AmOn process had high efficiency on nitrogen and phosphorus removal.
