Abstract: A method for treating pentachlorophenol-treated wood is provided to recycle the treated wood, and reuse the recovered solvent as an extraction solvent by recovering a solvent from a pentachlorophenol extract. A method for treating pentachlorophenol-treated wood comprises the steps of: crushing the pentachlorophenol-treated wood, adding a solvent to the crushed wood, and performing solvent extraction and centrifugation; distilling the objected pentachlorophenol extract to separate the solvent and residues containing pentachlorophenol; and treating the separated residues containing pentachlorophenol with supercritical water oxidation at a pressure of 22.1 to 30 MPa, an excessive oxygen condition of 50 to 200%, and a temperature of 374 to 600 deg.C.

Abstract: An apparatus and method for chemical agent disposal by a 2-step process is provided to treat a chemical agent safely and completely, by converting the chemical agent into a substance harmless to a human being. An apparatus for chemical agent disposal includes: a hydrolysis reactor(10) to hydrolyze or neutralize a chemical agent and to obtain a nontoxic substance; and a super critical water oxidation device to supply process water and oxygen. The super critical water oxidation device is constituted by an oxidation reactor(20), a main body including the oxidation reactor, and a heater inside, a pressure reducing set, a separator(33) to separate a product into a gas substance and a liquid substance; a heat exchanger(34) to cool the product, a filter to remove any particles in the product, and a treated water reservoir(36) to reserve treated water and to recycle it as process water.
