A method for treatment of sewage sludge using ozone is provided to decompose organic matters of sewage sludge consistently and effectively through the oxidation reduction reaction by maintaining the flux of ozone to a predetermined range or more. A method for treatment of sewage sludge using ozone comprises controlling the flux of ozone to a range of 4 to 10 L/min, thereby constantly maintaining the ORP(Oxidation Reduction Potential) to consistently decompose organic matters of sewage sludge when treating sewage sludge through a reaction between ozone and sewage sludge. The reaction between ozone and sewage sludge is carried out for 2 to 7 hours. |
