The invention belongs to the field of water environment governance and particularly relates to a bacterium-alga filler strengthened combined type ecological floating bed and a water body purificationmethod therefor. The bacterium-alga filler strengthened combined type ecological floating bed comprises a filtering device, a purifying device and a strengthened adsorbing device which are arranged sequentially according to a water flow direction, so as to form a preliminary filtering-efficient purifying-advanced strengthened treatment repair process, and the water quality of water body can be effectively improved from an upstream to a downstream; the purifying device comprises an emergent-plant bed, a suspending filler layer, a microporous aerating layer, a submerged plant layer and an immobilized bacterium-alga filler layer which are arranged sequentially from top to bottom, the microporous aerating layer serves as a limit, an aerobic zone is formed upwards, and a hypoxic-anaerobic zoneis formed downwards throug
