Oxygen Process

Due to the characteristics of dissolved oxygen process, such as non-linear and time delay, the traditional control methods are not very ideal for the aeration quantity assignment in the major domestic wastewater treatment plants. An intelligent system that controls the aeration quantity of the wastewater treatment of biochemistry pools is adopted, which the feedback control and the intelligence model are used to keep the balance of aeration. Meanwhile, according to the concentration of dissolved oxygen, the rotational speed of the air blower is adjusted for the sake of saving energy. This control system has been realized by Schneider Premium TSX P57 PLC system and the results show that the system is stable and reliable.
