TREATING METHOD FOR WASTE SOLUTION FROM WET DESULFURIZATION AND DENITRATIONAPPARATUS FOR EXHAUST COMBUSTION GAS

摘要

PURPOSE:To reduce time required for hydrolysis to a minimum so as to increase treating capacity for waste solution by the hydrolysis of the waste solution under specified conditions in order to decompose N compounds contained in the filtrate to N2 by concentration, drying, and thermal decomposition of the filtrate which has been obtained through oxidation of the waste solution formed in desulfurization and denitration of exhaust combustion gas and separation of gypsum contained in the oxidized waste solution.
