The effluent quality of the wastewater treatment is significantly influenced by the amount of dissolved oxygen in the wastewater aeration tank. In this paper, we design a fuzzy control system to regulate the concentration of dissolved oxygen in the aeration tank based on the fact that the control process of dissolved oxygen concentration in actual engineering is characterized by nonlinearity, large fluctuation, and severe hysteresis. The dissolved oxygen concentration is real-time controlled by the control system using the dissolved oxygen concentration as the controlled variable and the aeration of the blower as the manipulated variable. The simulation of the fuzzy control system using MATLAB software demonstrates that the response of the control system to the level of dissolved oxygen in the aeration tank is accelerated, and the outcome has strong robustness and good stability. With this design, the aeration tank's energy loss is decreased while the efficacy of the wastewater treatment is maintained.
