APPARATUS FOR DENITRIFICATION IN PURIFIED WATER AND WASTEWATER TREATMENT FACILITY USING ELECTROLYSIS

摘要

PURPOSE: An apparatus for removing nitrate nitrogen using electrolysis is provided to enhance reduction reaction efficiency of nitrogen and nitrous acid nitrogen ion in a cathode chamber by blocking the reduction of nitrogen gas and oxidation using a cation exchange membrane. CONSTITUTION: An apparatus(100) for removing nitrate nitrogen using electrolysis comprises: titanium electrodes which are an anode(10) and a cathode(20) and platinum is spread on; a cation exchange membrane(30) which is installed between the anode and the cathode; a catalyst plate(40) which is plated with palladium/nickel and a palladium/copper and is installed around the cathode. The catalyst plate a Ni-Foam-palladium(Pd)-based catalyst plate, Cu-Foam-palladium(Pd)-based catalyst plate, or Ni-Foam-Cu-Pd-based catalyst plate.
