摘要
讨论了水厂自动投药控制系统的设计方法，提出了基于流动电流的检测技术和ＰＩＤ控制算法及广泛适用的自动加矾系统总体控制方案，并给出了该系统的建立和实际调试方法．
A method for designing the automatic alum dosage system of waterworks based on the streaming current detecting and PID control algorithms is mentioned.By the specific and practical way ,The system can be set up and regulated.This scheme can be wildly accommodated.
