Abstract: PURPOSE: A method for neutralizing regeneration waste of ion exchange resin in pure water manufacturing system is provided, in which carbon dioxide gas from a carbon dioxide stripping tower is used to neutralize a mixed regeneration waste solution of alkali and acid. CONSTITUTION: Waste acid solution generated from cation exchange resin tower(12) and waste alkali solution generated from anion exchange resin tower(16) flow into a mixed regeneration waste solution tank(21). At this stage, flue gas containing carbon dioxide gas exits a carbon dioxide stripping tower(14) through an exit valve(23) to the outside of system. As the mixed regeneration waste solution, however, exceeds pH 8.6, discharge of the mixed regeneration waste solution outside the tank is restricted because it goes beyond the maximum permissible guideline listed in environmental regulations. In such cases, flue gas containing carbon dioxide gas is supplied into the mixed regeneration waste solution tank by closing the exit valve(23) while opening a connection valve(22). Such operations cause excess alkali contained in regeneration waste solution to react with carbon dioxide gas for neutralization and it is represented by follow chemical equations: (i) CO2 + H2O ↔ H2CO3 ↔ H¬+ + HCO3, (ii) NaOH + H¬+ + HCO3 ↔ NaHCO3 + H2O.
