MEMBRANE-ELECTRODE ASSEMBLY, ELECTROLYTIC CELL USING THE SAME, METHOD AND APPARATUS FOR PRODUCING OZONE WATER, METHOD FOR DISINFECTION AND METHOD FOR WASTEWATER OR WASTE FLUID TREATMENT

摘要

This invention is to provide a membrane-electrode assembly, an electrolytic cell using the same, a method and an apparatus for producing ozone water, a method for disinfection and a method for wastewater or waste fluid treatment, by using which electrolysis reaction products or decomposition products obtained at the anode are produced at a high efficiency; channel pressure drop is minimized; and the apparatus is designed in compact size without sacrificing the production capacity. This invention relates to a membrane-electrode assembly comprising a solid polymer electrolyte membrane having a cation exchange membrane, an anode and a cathode tightly adhered to the respective surfaces of the solid polymer electrolyte membrane, with a plurality of through-holes with 0.1 mm or more in diameter over the entire surfaces of the anode, the solid polymer electrolyte membrane and the cathode, passing through these elements; an electrolytic cell using the membrane-electrode assembly; a method and an apparatus for producing ozone water; a method for disinfection; and a method for wastewater or waste fluid treatment.
