A treatment apparatus of the present invention includes a hermetic doorand a retortas an interface for taking out a gaseous emission containing vaporized substances from an object to be treated which is being heated in a reduced pressure state in a second hermetic chamberwhile maintaining conditions in the second hermetic chamber. When the retortis inserted into a first openingof the second hermetic chamber, the hermetic doorin an open state is shielded from the second hermetic chamber, whereby condensation of the gaseous emission at the hermetic door is prevented. Accordingly, condensates can be taken out while conditions such as temperature and pressure in the hermetic chamber are maintained without the treatment apparatus being stopped. The productivity of treatment is greatly improved by continuous operation of such a treatment apparatus.

Treating apparatus, treating method and method of treating soil

An object to be treated such as soil, burned fly ashes, or the like containing organic halides is introduced to a hermetically sealable thermal decomposition furnaceand heated under reduced pressure. Emitted gases of the object to be treated are treated so that the generation and recomposition of dioxins are supressed. A heated residue of the object to be treated is cooled after being purged with a purge gas which is organic halide-free and has no organic halide generating capacity. Thus, the concentration of organic halides remaining in the heated residue can be held to an extremely low level.
