Intelligent fusion control technique application research for biochemical wastewater treatment

摘要

The wastewater treatment process has the character of nonlinear, time-varible, uncertain and hysteresis and control process is very complex, the traditional control methods are difficult to carry out real-time control. This paper focuses on the characteristics of the urban sewage treatment to put forward a sort of the control strategy based on the intelligent fusion for the sewage parameter. The paper analyzed the key parameter needed to be controlled and the process characteristic of polluted water treatment, discussed the fusion strategy for the polluted water parameter control, constructed the structure model of controller, studied the control algorithm, and made the contrast research on simulation experiment based on the control model. The simulation experiment verified that the fusion control strategy proposed by the paper would be better in dynamic and static quality by than PID control strategy. The Simulation results show that the fusion control strategy has strong robustness. Its control quality is relatively good.
