The invention relates to a mass transfer disc capable of effectively improving the mixing intensity and mass transfer rate of a single-phase or multi-phase system and belongs to the technical field of chemical equipment. A single face or two faces of the mass transfer disc are divided into multiple areas, and the multiple areas are provided with multiple guide ribs and/or guide grooves; the multiple areas are in regular and/or irregular shapes; the regular shapes are that multiple fan-shaped areas are arranged in a uniform divergence mode with the mass transfer disc as the center and/or multiple concentric circle-shaped areas are arranged with the mass transfer disc as the center; the edge of the mass transfer disc is provided with multiple guide ribs or guide grooves which are in regular and/or irregular shapes, and the regular shapes are lines, arcs or regular polygons; the guide ribs are 0.1-20 mm high, and the guide grooves are 0.1-20 mm deep. By the adoption of the mass transfer disc, the mixing intensity and mass transfer rate of the single-phase or multi-phase system can be effectively improved.
