The invention discloses efficient biological deodorization equipment. The efficient biological deodorization equipment comprises a dripping filter (1), wherein the dripping filter (1) is successively provided with a demister (9), a first spray thrower (71), a first porous aggregate bed layer (61), a second spray thrower (72), a second porous aggregate bed layer (62) and a gas diffuser (5) from top to bottom; the gas diffuser (5) is communicated with an air blower (2), and the bottom of the dripping filter (1) is respectively communicated with a liquid inlet of a fungus liquid tank (3) and a liquid inlet of a first water pump (41); a liquid outlet of the fungus liquid tank (3) is communicated with the liquid inlet of the first water pump (41), a liquid outlet of the first water pump (41) is respectively communicated with the liquid inlet of the first spray thrower (71) and a liquid inlet of second spray thrower (72), and the fungus liquid tank (3) is internally provided with deodorization fungus liquid. The efficient biological deodorization equipment provided by the embodiment of the invention has the advantages of improving the growth rate of a biological membrane, shortening the growth cycle of the biological membrane, improving the deodorization capacity, and effectively preventing the porous aggregate bed layer from being blocked.
