The present invention removes the particulate matter contained in the odor gas introduced by the operation of the blower 160 by using the washing water and the particulate matter removal unit that is supplied through the washing water supply unit and can be discharged through the washing water discharge unit Cleaning tank 110； two chemical tanks 141 and 142 each containing caustic soda and sulfuric acid as a ph neutralizer to supply a ph neutralizer to the cleaning tank 110 through a ph neutralizer supply unit； Microorganisms caused by the microbial fluid sprayed from the nozzles 170 spaced apart from the plurality of bio-filters 121 arranged alternately in a zigzag manner to arrange a plurality of bio-filters 121 arranged downward in a straight line form from top to bottom. A bio-filtering unit 120 to form a liquid film on the front surface of the plurality of bio-filters 121； A microbial storage tank 150 that stores microorganisms or nutrients for removing odors； And a microbe or nutrient supplied from the microbial storage tank 150 through the microbial supply unit, water supplied from a water source through the water supply unit, and the nozzle 170 toward the plurality of biofilters 121 through the microbial fluid circulation supply unit. ), The supply of oxygen from the air blower 190 to the microbial liquid formed by mixing the microbial liquid flowing down through the plurality of bio-filters 121 among the microbial liquid sprayed and maintaining the microbial growth temperature in advance It includes a microbial activation tank 130 for a time set in the, the plurality of bio-filter 121, the hook-type locking piece (21-1a) to induce individual alignment on the grid frame； A hollow pipe 21-1 that is interconnected with the engaging piece 21-1a and is provided with a plurality of through holes 21-1h； And a breathable woven fabric (21-2) woven in a cylindrical shape to fit into the pipe (21-1) but woven from polyethylin (PE) microfiber. It is about deodorizer.본
