| 摘 要： | 利用系统动力学原理,并根据活性污泥模型,构建Orbal氧化沟系统脱氮过程模拟的系统动力学模型。通过与实际情况相比发现,将模型分解为溶解氧模块、COD去除模块和TN去除模块是合理的,模拟发现减少转碟数量可以提高氧化沟系统脱氮效果。通过与实际运行的Orbal氧化沟进行对比发现,减少曝气转碟数量后,总氮去除率70%,比去年同期提高30%。 |

| Abstract: | In this study,system dynamics was applied to simulating nitrogen removal in Orbal oxidation ditch.Based on the activated sludge model No.1,the model was divided into dissolved oxygen sector,COD removal sector and total nitrogen removal sector,it was showed that reducing the number of the aeration disc could enhance the nitrogen removal efficiency,and compared with the monitored data,after reducing the number of the aeration disc,the nitrogen removal efficiency was increased to 70%,which was 30% higher than that of the same period of last year. |
| Keywords: | system dynamics oxidation ditch wastewater treatment |
