Optimization of Aeration Tank Process based on Nonlinear Constrained Wastewater Treatment

针对污水处理曝气池过程中关于COD问题的优化,通过定量分析、相关分析、变量控制等方法,建立了主成分分析、时间序列分析、非线性预测、SQPM非线性约束等模型,得到了活性污染泥浓度和氧化还原位点对出口COD的时间延迟影响程度最大,出口COD的最优非线性预测函数,为使COD浓度稳定在一定水平各指标浓度调节额等结论.

For sewage aeration pool of COD problem in the process of optimization, through quantitative analysis, correlation analysis, variable control method, establishing the principal component analysis, time series analysis and nonlinear prediction, SQPM nonlinear constraint model, got the active mud pollution concentration and the REDOX sites for COD of the impact of time delay, the biggest export COD nonlinear prediction function, the optimal stability for the COD concentration in a certain level of concentration adjustment amount for each indicator, conclusion.
