The mixed odor of the halogen-containing compound and the biomass garbage can cause more serious pollution (high toxicity and low content) to the environment in the processes of collection, transportation, accumulation and disposal of the household garbage.
The most common odor of the composite odor is corresponding to the odor by a spraying method, but the composite odor only solves the sensitivity of people on smell, and cannot be truly degraded on various characteristic pollutants. There are three main internationally recognized deodorizing methods: biochemical, physical adsorption and medium-high temperature oxidation. If the medium-high temperature oxidation process is adopted for treatment, the treatment cost is high, and simultaneously, under the condition of high-temperature oxidation, a large amount of dioxin or various precursors are generated in many times, and if the dioxin is not effectively controlled, the dioxin becomes harmful environmental hormone which destroys the human immunity and then influences the health; the activated carbon can be recycled to a certain degree by adopting a physical adsorption method, but a new hazardous waste source can be formed finally; the land occupation and investment and reaction of biological processes are often also short panels of the process.
Particularly, the invention aims at solving the complex odor generated by thousands of domestic garbage transfer stations which are closely related to the life of people in domestic operation, and how to realize the efficient and low-cost implementation of removing mixed odor under the normal temperature condition and simultaneously realize the synergistic treatment of separating out the residual degraded substances in the waste gas and removing the residual degraded substances out of the gas flow is the gist of the invention.

H2S+O2-O＋>SO3+H2O，
NH3+O2-O2+－＞NOX＋H2O，
VOCS+O2-O2+－＞CO2+H2O；
