<p>PROBLEM TO BE SOLVED: To provide a method for supercritically oxidizing org. waste water by which the deposition of salt on the wall surface of a reaction vessel is prevented, hence the clogging and corrosion of the vessel is effectively obviated, the frequency in replacing the vessels is decreased, the running cost is lowered, and the consumption of energy to prevent the salt deposition is low. SOLUTION: A fluid contg. at least water, a mixture of inorg. matter and org. matter or the org. matter chemically combined with the inorg. matter is supplied from one end of a reaction vessel 4 into a reaction region 7 of supercritical water oxidation formed in the reaction vessel 4 consisting of a porous cylinder to bring about supercritical water oxidation, and air is injected into the region 7 from the outside through the porous cylinder forming the vessel 4 to prevent the deposition of salt.</p> |
