The embodiment of the invention discloses a deodorization method integrating an environment-friendly enzyme deodorant and fog gun equipment. The deodorization method comprises the following steps of:S1, deodorant preparation: inoculating beer yeast, lactobacillus acidophilus, lactobacillus plantarum and bacillus subtilis, mixing the beer yeast, lactobacillus acidophilus, lactobacillus plantarum and bacillus subtilis, carrying out fermenting, carrying out aerobic fermentation for 60-84 hours, and carrying out anaerobic fermentation for 5-9 days to obtain the environment-friendly enzyme deodorant; S2, carrying out equipment installation, specifically, placing the fog gun equipment in a refuse landfill, and connecting pipelines, the connecting the fog gun equipment to a water source; and S3,adding the deodorant, namely adding the environment-friendly enzyme deodorant prepared in the step S1 into an agent box of spraying equipment. According to the method, the environment-friendly enzymedeodorant is automatically sprayed to the refuse landfill through the fog gun equipment, and the spraying time, the spraying amount and the fog drop size can be well and automatically controlled; theenvironment-friendly enzyme deodorant fog drops fully react with odor molecules, and therefore, a large amount of deodorant and labor are saved, a good deodorization effect is achieved, and the costcan be saved while efficient deodorization is achieved.
