▎ 摘　　要

NOVELTY - Preparing multi-component electro-wet combined catalytic modified electrode membrane, comprises (a) adding graphene oxide and polyvinylpyrrolidone into N-methylpyrrolidone, ultrasonically dispersing, adding polyethersulfone, transferring to water bath in pot, heating, ultrasonically degassing for 2 hours, (b) using polyacrylonitrile-based carbon fiber cloth as base, spreading polyacrylonitrile-based carbon fiber cloth on glass plate, and iron polyacrylonitrile-based carbon fiber cloth with steam iron, pouring casting solution on polyacrylonitrile-based carbon fiber cloth, utilizing scraper to scrape film, (c) dissolving yttrium oxide and cobalt oxide in water to prepare composite impregnation solution, placing electrode pre-membrane in aqueous ethanol solution for pretreatment, dissolving porogen polyvinylpyrrolidone to create pores, washing with deionized water, and soaking in composite dipping solution, and (d) modifying Y-Co/GO/PES membrane. USE - The method for preparing multi-component electro-wet combined catalytic modified electrode membrane for sewage treatment device and printing and dyeing, leather, paper making, cosmetic, paint, rubber, plastic, pesticide, wood, and preservative industries. ADVANTAGE - The method improves the traditional advanced oxidation treatment after solid-liquid mixing condition, saving the processing procedure and time, and reducing the processing cost as much as possible. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a sewage treatment device. DESCRIPTION OF DRAWING(S) - The drawing shows a whole structure diagram of the sewage treatment device (Drawing includes non-English language text).
