Proportional Control of Dissolved Oxygen Concentration of Sewage Water Treatment in Oil Field

Abstract:

Activated sludge method is mainly used to sewage water treatment of water injection system in oil field, dissolved oxygen of sewage pond plays a important role in the sewage water treatment process. The proportional control algorithm of dissolved oxygen concentration is developed based on a first time delay model, and the parameter values of the controller is determined by using stability margins design approach. Simulation results are provided to illustrate the design procedure and the effectiveness of the proposed methods. When applying to the wastewater treatment system based on activated sludge, this method can achieve a satisfied treating performance with robustness. Simulation results are given to demonstrate the design procedure and the effectiveness of the proposed methods.
