摘要： PROBLEM TO BE SOLVED: To provide a treatment technology for an object to be treated soil containing dioxins with superheated steam without causing lowering of treatment efficiency even if moisture content of the object is high, and to reduce load of treatment process of exhaust gas generated after treatment.
SOLUTION: The waste treatment apparatus has a superheated steam generator 2 generating superheated steam of 300°C or higher of roughly atmospheric pressure. Most of the object to be treated is decomposed by continuously bringing superheated steam generated in the superheated steam generator 2 into contact with the object 10 like waste in a treatment tank 3; part of the object is volatilized; and the object 10 is heated by an auxiliary heating device 4 by hot air when treating in the treatment tank 3. The object 10 is dried in advance by heating in an object heating device 11 by hot exhaust gas exhausted when treating in the treatment tank 3.
