基于模糊控制的污水处理实验研究

A Kind of Sewerage Treatment Experiment System Based on Fuzzy Control

分析了污水处理中溶解氧控制和化学需氧控制的重要性及复杂性.针对溶解氧量和化学需氧量这两个参数的变化无确定的规律可循的特点,提出用模糊控制的方法控制污水处理中的溶解氧量和化学需氧量.对溶解氧量和化学需氧量分别设计了双输入的模糊控制器,并且设计了以单片机为核心的模糊控制系统.实验结果表明,该控制系统能够保证污水处理后达标排放.

The importance and complexity of DO and COD control in sewerage are analyzed. According to the characteristics of DO and COD, fuzzy control methods are applied in DO and COD control. Two fuzzy controllers with two inputs are designed respectively for DO and COD control. A fuzzy control system based on single chip is designed. Experiment results show that the control system can ensure quality of wastewater processed.
