The invention discloses an organic refuse deodorant. The organic refuse deodorant is prepared from the following raw materials in parts by weight: 40-60 parts of edible mushroom waste, 1-2 parts of bacillus licheniformis, 1-2 parts of nitrite bacteria, 1-2 parts of thiobacteria, and 1-2 parts of thiobacillus denitrificans. According to the invention, beneficial microorganisms take the edible mushroom waste as a growth accelerant; the obtained organic refuse deodorant can decompose hazardous substances containing putrid odor, such as ammonia, amine salt and sulfides; other substances, such as microbial inoculum, in the organic refuse deodorant achieve a mutual synergistic effect, so that the purposes of deodorization and decrement are achieved, and the organic refuse is turned into valuable from waste for producing a bio-organic fertilizer. The organic refuse deodorant is used for realizing deodorization and decrement on the organic refuse. Compared with the prior art, the organic refuse deodorant has the advantages of small productive investment, low production cost, environmental friendliness, high treatment efficiency, wide adaptation, and convenience in use.
