AI Technical Summary
In existing water treatment technologies, the fixed control of flocculant dosage cannot adapt to dynamically changing operating conditions, resulting in poor coagulation effect or waste of reagents. Furthermore, the detection of turbidity in the produced water has a time lag, affecting the control accuracy.
A fractal dimension-based intelligent control method for coagulation dosing is adopted. The fractal dimension is calculated by real-time monitoring of the morphological characteristics of flocs, and the feedforward compensation and initial dosage are generated by combining the influent flow rate. A cascade control structure is constructed to achieve rapid response and precise adjustment of flocculant dosing.
It significantly improves the control precision and dynamic response speed of the coagulation process, overcomes the lag in turbidity of the product water, enhances the ability to suppress fluctuations in influent flow rate, and ensures stable effluent quality.
