Zusammenfassung:PROBLEM TO BE SOLVED: To treat a cyan waste liq. at a low cost. SOLUTION: A cyan decomposing pressure vessel 1 and a heating furnace 2 are integrated, a cyan waste liq. is preheated and supplied into the pressure vessel 1, the waste liq. in the vessel 1 is heated, pressurized and thermally hydrolyzed in the furnace 2, the gaseous ammonia as the decomposition product is used as a fuel for the furnace 2, and the fuel cost is reduced.
