<p>PURPOSE: A wastewater treatment method capable of minimizing the scale of basins with reduced excess sludge generation is provided. CONSTITUTION: The apparatus is provided with an aeration tank in which wastewater is brought into contact with microorganism media under aerobic conditions and a complete oxidation tank, liquid in the complete oxidation tank is filtered by passing through a separation membrane, and the filtrate is discharged. Preferably, an s-BOD sludge load in the complete oxidation tank is 0.1 kg-BOD/kg-MLSS.day or below.</p> |
