The invention relates to a cement-based composite carbon electrode, and a preparation method and application thereof. The electrode comprises a composite material and Pt-Bi supported on the compositematerial, the composite material comprises, by weight, 40-50 parts of cement, 25-35 parts of fly ash, 10-20 parts of activated carbon and 5-15 parts of graphite powder, and the composite material is also doped with graphene. The preparation method comprises the following steps: preparing an activated carbon-graphene compound, then preparing a slurry solid, carrying out cement curing to obtain thecomposite material, and loading Pt-Bi on the composite material to obtain the cement-based composite carbon electrode. The cement-based composite carbon electrode is used for degrading pollutants in sewage. Compared with electrodes in the prior art, the electrode in the invention has the advantages of greatly improved adhesion, prolonged service life, realization of efficient and rapid degradationof non-biodegradable pollu
