Activated sludge wastewater treatment method and activated sludge wastewater treatment equipment

摘要

PPROBLEM TO BE SOLVED: To provide a control method of high precision for an activated sludge type wastewater treatment apparatus based on a plurality of the measured amounts in the wastewater treatment apparatus. PSOLUTION: In the activated sludge type wastewater treatment method adapted to the activated sludge type wastewater treatment apparatus wherein a nitrification/denitrification process is performed using an aeration device, at least the concentration of ammoniacal nitrogen and the concentration of nitrate nitrogen in the wastewater treatment apparatus are measured or the concentration of dissolved oxygen or the flow rate and/or the concentration of wastewater is measured along with these concentrations, the optimum operation values of the respective measured amounts are set, a control signal is successively operated and outputted from the respective measured amounts on the basis of the optimum operation values using Karman operational processing and linear operational processing, and the driving of the aeration device is controlled from the control signal.
