The objective of this work was to optimize (minimize) the compressed air required to control the rate of ammonia removal in a commercially operated wastewater bioreactor, while still maintaining operation within environmental consent limits. In order to do this, a nonlinear dynamic model based on the International Association on Water Quality (IAWQ) activated sludge model No. 3 was developed, expressing the nitrification kinetics and hydraulic dynamics of the system. From this model a steady state representation of the plant was derived, and simulated for various load characteristics experienced at the facility, and as a result an optimal load profile was developed for the compressed air distribution to the four aerobic zones. The optimal load profile will ensure that the amount of compressed air required to control the rate of ammonia removal is optimized.
这项工作的目标是优化（最小化）控制商业运行的废水生物反应器中氨去除率所需的压缩空气量，同时仍在环境许可范围内维持运行。为了实现这一目标，基于国际水质协会（IAWQ）活性污泥模型第3号开发了一个非线性动态模型，该模型表达了系统的硝化动力学和水力动力学。从该模型中得出了该工厂的稳态表示，并针对该设施所经历的各种负荷特性进行了模拟，结果为向四个好氧区分配压缩空气制定了最佳负荷曲线。最佳负荷曲线将确保控制氨去除率所需的压缩空气量得到优化。
