METHOD AND SYSTEM FOR TREATING NITROGEN-CONTAINING COMPOUND

摘要

A method for treating a nitrogen-containing compound in the water to be treated by an electrochemical process, characterized in that a cathode comprises a metal material comprising an elecrocondutive material containing an element belonging to Group Ib or IIb of the Periodic Table, or comprising an elecrocondutive material and the element belonging to Group Ib or IIb covering the elecrocondutive material. The method allows the removal of a nitrogen-containing compound with good efficiency and also the miniaturization and the cost reduction of a system for the treatment.
