PROBLEM TO BE SOLVED: To realize stable and durable heat treatment by preventing mixture of steam and thermally cracked gas. SOLUTION: The heat treatment for a water containing organic matter heat-treats a target of treatment comprising a water containing organic matter in heat-treating furnaces in multiple stages. When the treatment target, after heat-treated in the front-end heat-treating furnace (drying furnace 1) that removes moisture contained in the treatment target as steam, is further heat- treated in the back-end heat-treating furnace (thermal cracking furnace 3), the moisture-removed treatment target is fed to the back-end heat-treating furnace via a gas dividing means 2 for dividing a gaseous phase whose principal component is steam generated by the front-end heat treatment and a gaseous phase whose principal component is thermally cracked gas generated by the back-end heat treatment.
