<p>PROBLEM TO BE SOLVED: To make exhaust gas and a residue harmless by a method wherein a harmful component contained in a material to be treated is deposited by decomposing with a thermally treating furnace, and simultaneously allowed to react with an alkaline material to generate a harmless chloride. SOLUTION: Two thermally treating furnaces 10. 20 equipped with a heating means for heating from outside a cylindrical body 11 are provided, and arranged by being horizontally placed up and down or on a plane. Then, a discharge opening 14 side of one side thermally treating furnace 10 thereof is communicated to a supply opening 23 side of the other side thermally treating furnace 20 by a duct 17, a harmful component is deposited by decomposing from a material to be treated with one side thermally treating furnace 10, and besides allowed to react with a treating agent comprising an alkaline material to execute a decomposition reacting treatment for generating a harmless chloride. The material to be treated after the decomposition reacting treatment is transferred to the other side thermally treating furnace 20 via the duct 17, and a volume-reducing treatment such as a charcoal fire or the like is executed with the thermally treating furnace 20.</p> |
