In recent years, China emphasizes environment-friendly treatment and standard treatment in the solid waste reduction treatment industry. In the process of reducing and treating solid waste, if the emitted pollution gases such as waste gas and dust are directly discharged without treatment, a large amount of toxic and harmful gas elements such as dust can cause adverse effects on the surrounding environment. At present, the pollution problem in the industry can be effectively solved by the complete equipment for reducing and treating the solid waste. Complete equipment for reducing and treating solid wastes becomes novel efficient treatment equipment for treating the solid wastes such as livestock and poultry manure produced by a farm, domestic organic wastes produced in cities, fruit and vegetable wastes and the like.

Complete equipment for reducing and treating solid wastes adopts an aerobic fermentation composting process, organic matters in the wastes are utilized to carry out biological decomposition and decomposition, a small amount of odor is inevitably generated in the fermentation process, for example, most of gases generated in the fermentation process are harmless gases such as water vapor, CO2 and the like and a small amount of NH3 and H2S, and in order to deal with odor pollution in the process of reducing and treating the solid wastes, a physical deodorization mode through adsorption and a biological deodorization mode through microbial decomposition are generally adopted at the present stage. But the harmless treatment of odor is difficult to be completed by adopting a single deodorization mode. A chinese utility model patent document named a two-tower type biological deodorization system discloses a two-tower system composed of a biological deodorization tower and an adsorption tower which are connected in sequence. Two layers of biological fillers are sequentially arranged in the biological deodorization tower from top to bottom, and a spraying device is arranged above each layer of fillers; the adsorption tower is internally provided with a plurality of activated carbon layers and activated carbon storerooms from top to bottom in sequence. When the biological deodorization device is used, a single-tower biological packing layer or a double-tower biological packing layer and an active carbon layer can be selected according to requirements for treatment, and odor is discharged into the atmosphere after being treated by biological packing and sprayed water in the biological deodorization tower or is discharged into the atmosphere after being treated by the biological deodorization tower and then being adsorbed by the adsorption tower. The sprayed water is recycled to supply nutrients to the microorganisms. However, when the two-tower type biological deodorization system is used, odor is directly contacted with microorganisms in the biological filler without being treated, so that strains in the biological filler are easily damaged by substances such as high temperature, smoke in the odor, peracid, over-alkali and the like, and the service life of the biological filler is shortened.
