The invention discloses a multi-enzyme complex microecological probiotic deodorant, which is prepared from the following nine raw materials: a bacillus fermentation material, a yeast fermentation material, a lactic acid bacteria fermentation material, a photosynthetic bacteria fermentation material, protease, lipase, cellulase, spice and water. The multi-enzyme complex microecological probiotic deodorant has an efficient viable count of up to 5 billion/g, and the product is rich in bacillus, yeast, lactic acid bacteria, photosynthetic bacteria and protease, lipase, cellulase and other active enzymes to keep the air fresh, reduce the density of mosquitoes and flies, inhibit the growth of pathogenic microorganisms, and reduce the respiratory diseases of livestock, especially the respiratorydiseases prone to occur in animal breeding; the deodorant can quickly inhibit the growth of spoilage bacteria, effectively absorb and degrade ammonia nitrogen, hydrogen sulfide, methanethiol and othermalodorous harmful pollutants, has no harm to humans and animals and plants, no secondary pollution to the environment, and has the maximum removal rate of ammonia nitrogen of up to 95%, and the removal rate of hydrogen sulfide of up to 90%.
