Through experimental calibration and optimization algorithms, the optimal fractional-order parameters are determined to ensure the accuracy of the model. The fractional-order model is used to calculate the required chemical dosage, and the operation parameters of the dosing pump are adjusted in real time to ensure the accuracy and timeliness of chemical dosing. According to the fractional-order model, the operation parameters of the aeration system (such as fan speed, aeration time) are dynamically adjusted to optimize the microbial treatment effect. The fractional-order model is used to predict the sedimentation velocity and concentration of suspended solids, and the operation time and sludge discharge frequency of the sedimentation tank are adjusted to ensure the solid-liquid separation effect.

Calculate the Lyapunov exponent of the system to evaluate the degree of chaos of the system. Use chaos synchronization technology to make the states of the system at different time points converge, thereby controlling the chaotic behavior of the system. By making small perturbations to the input parameters of the system, regulate the operation state of the system to avoid falling into the chaotic region. Use the chaos control strategy to dynamically adjust the chemical dosage, aeration volume and sedimentation time to optimize the treatment process. Monitor the system response in real time, and adjust the control parameters through the feedback control loop to ensure the stable operation of the system.
