摘要
研究了废水(工业废水)pH控制过程中的明显非线性与时滞性特点,探讨了采用计算机处理系统,利用前馈数学模型控制,后馈数学模型反馈修正、自动控制中和剂投加量的方法,来有效控制废水的pH值。
Obvious non- linearity and characteristics of time delay during controlling the pH value of waste water were studied in the paper. The pH value is controlled effectively using computer processing system, feed forward mathematical mode control, feed backward mathematical mode feedback modification and auto- control neutralization agent addition.
