The invention discloses an anti-corrosion conductive ceramic electrode material for sewage and sludge treatment and a preparation method of the anti-corrosion conductive ceramic electrode material. The anti-corrosion conductive ceramic electrode material is characterized in that carbon is used as aggregate; the anti-corrosion conductive ceramic electrode material is prepared from artificial graphite, graphitized mesocarbon microbeads, a reinforcement binder, graphitized carbon fiber and E-44 epoxy resin. The preparation method comprises the following steps of adding a Ti4O7 functional additive having strong electrode performance, simultaneously adding one or several of ceramic anti-wear-corrosion components of TiB2, TiO2, TiC, B2O3, SiO2 and SiC, carrying out solidification, compression molding and high-temperature sintering after adding a mixing solvent and completely mixing the mixture, and finally preparing the anti-corrosion conductive ceramic electrode material. According to the anti-corrosion conductive ceramic electrode material and the preparation method, disclosed by the invention, aiming at an actual working situation of a sewage and sludge treatment environment, unique anti-corrosion components are added while low specific resistance of the anti-corrosion conductive ceramic electrode material is ensured, not only are wearing resistance and corrosion resistance of traditional ceramics obtained, but also excellent conductivity and excellent electrochemical performance are obtained, and the service life is up to more than 3500 hours.
