The application discloses an AnDMBR dynamic membrane assembly for sludge anaerobic digestion, which comprises a sealed membrane frame, a plurality of flat plate membranes and a plurality of detachable aeration pipes; the sealed membrane frame is used for bearing various components of the AnDMBR dynamic membrane assembly and is in the shape of a cuboid composed of a stainless steel grid; the plurality of flat plate membranes are arranged in parallel and equidistantly in the sealed membrane frame; a membrane water outlet is arranged above the flat plate membranes, and the height of the membrane water outlet is higher than the upper surface of the sealed membrane frame; the gap between the plurality of flat plate membranes is filled with conductive particles; the plurality of detachable aeration pipes utilize the circulating biogas from the air guide holes to form a cross flow on the surface of the flat plate membranes and disturb the conductive particles between the flat plate membranes. The application effectively solves the problem of flat plate membrane surface mud cake deposition caused by the operation of AnDMBR at high sludge concentration, prolongs the service life of the dynamic membrane assembly, and improves the anaerobic digestion performance of the reactor.
