污水处理过程的多变量预测控制

Multivariable Predictive Control of Wastewater Treatment Process

摘要: 提出了一种针对活性污泥法污水处理系统的多变量预测控制策略,并将该策略应用到污水处理的脱氮上,对污水中氨氮与硝酸氮浓度实施多变量预测控制。通过对国际水质协会活性污泥1号模型(A SM 1)的闭环计算机仿真表明,应用该算法可实现对污水中氮含量浓度的有效控制,减小系统输出的波动,稳定最终输出。

Abstract: A multivariable predictive control strategy on activated sludge wasterwater treatment process is proposed.This strategy is based on activated sludge math model No.1,controlles the concentration of NO~-_3 and NH~ _4 in the last non-aerated reactor.Simulation results show that the controller achieves a high stability in a very short time.
