| 摘 要： | 利用基于ASM2D的数学模型对上海石洞口污水厂UniTank工艺内氨氮浓度的动态特性进行了仿真研究,发现该流程反应器氨氮浓度具有非稳态特征.反应器内氨氮浓度的变化规律与曝气时间设定及进水时间设定有关.增加曝气强度,能降低边池及中池的氨氮浓度,相应增大边池及中池的硝态氮浓度.

| Abstract: | Dynamic behavior of ammonia-nitrogen in a UniTank process in Shanghai Shidongkou Urban Sewage Treatment Plant was simulated by using a mathematic model basing on ASM2D. The results show that ammonia-nitrogen in the UniTank process is on a non-steady state. Variation of the concentration is influenced by the schedule of the aeration in reaction vessels and the schedule of the sewage entrance to the vessels. Strengthening aeration may decrease the ammonia-nitrogen concentration and correspondingly increase the nitrate-nitrogen in the vessels. |
