An apparatus and a method for ozone-treating biosludges and of reducing biosludges occurring upon a biological treatment of aqueous organic waste, wherein the apparatus is made up of a plurality of reactors for effecting the ozone treatment of the biosludge by contacting the biosludge with an ozone-containing gas, biosludge passages for flowing the biosludge to be ozone-treated through all the reactors in series, gas supply means for supplying the ozone-containing gas to each of the reactors, a pressurization means for maintaining each of the reactors under a pressurized condition and stirrers each disposed in each reactor for realizing a nearly equalized ozone absorption rate for all the reactors.
