description	An electrode for the electrochemical degradation of biomass wastewater, and a preparation method therefor and the use thereof. The preparation method for the electrode comprises the following steps: subjecting a planar boron-doped diamond electrode to a surface oxidation pretreatment; adding a mixed solution of the pretreated boron-doped diamond electrode, a metal salt and a precipitant to a reaction kettle to perform a hydrothermal reaction, and uniformly growing a metal layer on the surface of the electrode; placing the metal/boron-doped diamond electrode into a tubular furnace, introducing hydrogen thereto to perform high-temperature etching under the catalytic action of the metal, and cooling same to obtain a metal/porous boron-doped diamond electrode; and soaking the metal/porous boron-doped diamond electrode in a strong acid to obtain a porous boron-doped diamond electrode. By means of the method, the active area of the electrode is effectively increased, the anodic oxidation efficiency is improved, and
