| Abstract: | Aimed at the large fluctuation of neutralization agent concentration and the serious lag of neutralization action during the process of acid waste water neutralization, a mathematical model of the controlled object-pH-value of waste water neutralization is built up. Adopting double-closed-loop accommodate system, the hardware circuit with the core of the 8031 single-chip microcomputer has been designed and the software program with the core of the large-lag sampling algorithm and PI strategy has been designed. |
