This scheme introduces the malodorous waste gas into the microbial deodorization box by starting the wind-inducing device. When the waste gas contacts the microbial soil When filling the layer, microorganisms are used to absorb and transform hydrogen sulfide, ammonia and other gases in the exhaust gas. At the same time, the water vapor in the exhaust gas reacts with the sodium peroxide powder in the reaction powder to generate oxygen and release heat at the same time. On the one hand, it can Provide oxygen for the life activities of microorganisms. At the same time, with the help of the deliquescence effect of sodium hydroxide in the product, the absorption of water vapor in the exhaust gas can be further improved, thereby improving the moisture absorption effect of the entire elastic connecting conduit, thereby improving the water vapor and water vapor. The reaction efficiency of sodium peroxide powder, on the other hand, with the help of the generated oxygen and the reaction of reducing iron powder, it can further generate heat, thereby accelerating the conversion efficiency of microorganisms to waste gas.
