Real-Time Control of Sewage Aeration Treatment System Based on Fuzzy PID

In recent years, China has improved the standard of river sewage treatment, and the requirement of “double carbon” has made the study of accurate aeration control an important research content. In order to reduce the energy consumption of aeration, improve the automation degree of river sewage treatment, this paper for the traditional PID controller in the dissolved oxygen control adjustment time is too long and overshoot, the fuzzy control algorithm is introduced based on the PID algorithm, and controls the dissolved oxygen concentration in the river, so that it quickly reachs the set value. In the river sewage aeration treatment, the fuzzy PID controller can control the amount of dissolved oxygen in the water by adjusting the frequency of the blower, achieve accurate control, and further improve the control performance. The simulation experiment results prove that the improved fuzzy PID controller significantly reduces the overshoot and control time, and the control system can control the dissolved oxygen concentration to reach the set value more quickly and accurately after obtaining the optimized setting value, and improves the control effect.
