the air in the deodorizing chamber is used as first deodorizing tail gas and is discharged out of the deodorizing chamber by a second active fan, and the air with ozone in the deodorizing chamber is replaced by matching with the first active fan, so that the ozone concentration is maintained;
in the deodorizing working process of the deodorizing chamber, the leakage liquid in the garbage seeps out and drips into the deodorizing liquid collecting tank, and the deodorizing chamber is periodically started to spray the cleaning liquid by the spray cleaning device to clean the deodorizing chamber, wherein the leakage liquid and the cleaned cleaning liquid contain substances with easily volatile malodorous gas or are dissolved with malodorous gas, and sewage mixed in the deodorizing liquid collecting tank is conveyed into the treating tank by the malodorous liquid pump;

meanwhile, the gas discharged from the treatment pool is taken as second deodorizing tail gas to enter a tail gas deodorizing device, the water content in the second deodorizing tail gas is increased after the second deodorizing tail gas passes through the treatment pool, and more free hydroxyl groups can be generated by the action of a low-temperature plasma component in the tail gas treating device, so that organic components, such as putrescine, cadaverine and the like, which are not easy to dissolve in water, remained in the second deodorizing tail gas are reacted and oxidized, further, the discharged tail gas is free from bad odor, an ultraviolet lamp is used for activating ozone in the second deodorizing tail gas, accelerating the reaction of the ozone, reducing ozone in the discharged tail gas, and avoiding bad influence on the environment caused by ozone which is not decomposed by the self in time;
therefore, the system treats the malodorous gas dissipated by the garbage and source substances for dissipating the malodorous gas, ultraviolet light is used in the deodorizing room to play a role in sterilizing, fermentation of the garbage in the short-term storage process of the transfer station is slowed down, the malodorous gas is removed, the generation of the subsequent malodorous gas is reduced, and compared with the existing method for treating the malodorous gas only, the system is more efficient and reduces the bad influence of the malodorous gas dissipated to the environment when the garbage is transported from the garbage transfer station to a final treatment point.
Preferably, the cleaning liquid for cleaning the deodorizing chamber by the spray cleaning device is an alkaline liquid.
By adopting the technical scheme, ozone has extremely strong oxidizing property under the activation of ultraviolet light, and can oxidize the inner wall of the outer box body and the metal surface of the deodorizing indoor device to form a compact peroxide film, and alkaline cleaning liquid is used for preventing the peroxide film from being damaged, so that the inner wall of the outer box body and the deodorizing indoor device are prevented from being corroded; meanwhile, the sewage obtained by using the alkaline cleaning liquid is alkaline, so that the absorption capacity of the treatment tank on acid gas generated by decomposing malodorous gas is improved.
