    • PURPOSE: Provided are a method and a system for controlling amount of oxygen to be supplied to wastewater, considering concentration and amount of organic material in the wastewater. CONSTITUTION: The method comprises the steps of introducing wastewater into an aeration tank with a DO (dissolved oxygen) meter and an ORP (oxidation reduction potential) meter, transmitting data of DO and ORP to a PLC (programmable logic controller), transmitting a signal to a PSA (pressure swing adsorption) to generate and supply a first gas with 90% of oxygen concentration to the aeration tank when the data indicate a figure lower than reference data for a predetermined time, transmitting a signal to the PSA to generate and supply a second gas with 60% of oxygen concentration to the aeration tank when the data indicate a figure greater than the reference data for a predetermined time, and transmitting a signal to the PSA to generate and supply a third gas with 21% of oxygen concentration to the aeration tank when the data indicate a figure greater than the reference data for a predetermined time.
