<p><P>PROBLEM TO BE SOLVED: To provide a treatment method of sludge which prevents the reduction in electrolytic efficiency to hold a stable electrolytic treatment performance by removing a scale and sludge scum, and enables the reduction of excess sludge to a minimum amount while preventing the decrease in sludge volume reduction effect. <P>SOLUTION: The treatment method of sludge for mineralizing the excess sludge generated associated with activated sludge treatment of organic waste water by carrying out electrolytic treatment and recirculating electrolytic treatment sludge to a biological reactor to carry out biological treatment comprises blasting high-pressure water between electrode plates 7 placing a cathode 71 and an anode 72 in parallel from above a water surface. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
