摘要
耦合两步硝化-反硝化活性污泥法数学模型和对流-扩散标准形式二沉池分布式参数模型,建立了一个新的活性污泥-沉淀池动态模型。基于MATLAB/Simulink仿真平台,组态完成了某常规完全混合式AO工艺系统的仿真模型。经过模拟进行调控优化预演,所建模型能完整体现系统的状态变量随各操作变量变化而呈现出的时变性、非线性、耦合性、大滞后性等特征;所建模型可以作为工艺智能分析、挖掘、优化、预测的基本仿真备选工具。
A novel integrated activated sludge-settler dynamical model was established by integrating a two-step nitrificationdenitrification activated sludge model with a standard convection diffusion settler model. Based on the MATLAB / Simulink platform,a traditional CSTR AO process system was configured according to the integrated activated sludge-settler dynamical model. The model could representatively reflect the main characteristics of the wastewater treatment system,such as the time variation trait,nonlinearity trait,coupling trait and large time delaying trait,thus,the model could be used as an alternative tool for process intelligence analysis,data mining,optimization and prediction.
