PROBLEM TO BE SOLVED: To provide a waste heat recovery device for wet oxidation decomposition equipment of organic waste capable of recovering a heat of product from an oxidation decomposition furnace for wet oxidation decomposition equipment, cooling the product up to a desirable post-cooling temperature, heating liquid organic waste supplied to the oxidation decomposition furnace up to a desirable prescribed supply temperature with the recovery heat and, at the same time, preventing scale production due to carbonization etc. in a supply line of the liquid organic waste. SOLUTION: The waste heat recovery device for wet oxidation decomposition equipment having the oxidation decomposition furnace by which the liquid organic waste is subjected to wet oxidation decomposition in a subcritical state is provided with: a cooler which cools the product discharged from the oxidation decomposition furnace up to the prescribed post-cooling temperature through thermal exchange with heat medium; a preheater which raises the temperature of the liquid organic waste supplied to the oxidation decomposition furnace up to the prescribed supply temperature through thermal exchange with the heat medium; a heat medium circuit through which the heat medium is circulated between the cooler and the preheater; and a cooler which is inserted into the heat medium circuit and cools the heat medium.
