The non-linear and lagging usually appears seriously in the neutralization course of acid and alkali, it not only brings a great difficulties for PH value control, but also wastes a large amount of neutralizer, so PH value is recognized as one of the most difficult control variables.
酸碱中和过程通常呈现严重非线性和滞后性，给PH值控制不仅带来极大的不确定性，也浪费大量中和剂，为此PH值被公认为最难的控制变量之一。
The level of automation of the pH value control system in China relatively falls behind, research and development of automatic system with good control effects and easy realization has much practical mean.
我国污水处理pH值控制系统的自动化水平相对落后,开发出具有良好控制效果、易于实现的自动化成套系统具有现实意义。
