METHOD FOR REMOVING METAL MATERIALS AND ORGANIC MATERIALS FROM EDTA-METAL COMPOUND CLEANING WASTEWATER BY USING SUPERCRITICAL WATER TREATMENT

摘要

The present invention relates to a method for removing metal materials and organic materials from ethylenediaminetetraacetic acid (EDTA)-metal compound cleaning wastewater by using a supercritical water treatment and, more specifically, to a method for removing metal materials and organic materials from EDTA-metal compound cleaning wastewater by using a supercritical water treatment, which can remove the metal materials and the organic materials included in the EDTA-metal compound cleaning wastewater generated using EDTA during a chemical cleaning process in nuclear power plants or thermoelectric power plants through supercritical water treatment of the EDTA-metal compound cleaning wastewater.
