PROBLEM TO BE SOLVED: To provide an oxidative decomposition apparatus and method for solid organic substance-containing organic waste liquid which can oxidatively decompose the solid organic substance-containing organic waste liquid sufficiently without hindrance to make the waste liquid harmless at low cost in a short time without environmental load. SOLUTION: The oxidative decomposition apparatus for solid organic substance-containing organic waste liquid comprises a reaction column which receives the continuous supply of the solid organic substance-containing organic waste liquid and the supply of oxygen or air is fed, and carries out the wet oxidative decomposition of the solid organic substance-containing organic waste liquid in a subcritical state and converts the organic waste into an intermediate product comprising solubilized solid organic substances, and a catalyst column which is serially connected to the downstream side of the reaction column, receives the supply of oxygen or air, and mineralizes the intermediate product supplied from the reaction column by a catalyst. A milling device for milling and atomizing the solid organic substances in the solid organic substance-containing organic waste liquid supplied from the reaction column is disposed on the upstream side of the reaction column. The oxidative decomposition method uses the apparatus. COPYRIGHT: (C)2006,JPO&NCIPI
