Compared with urban domestic sewage, the odorous substances in the hospital sewage have less mass, stronger odor and larger danger after diffusion. The main components of the odor of the hospital sewage station are malodorous gases such as hydrogen sulfide, ammonia, methyl mercaptan, dimethyl sulfide, dimethylamine and the like, and a large number of pathogenic bacteria are carried by the malodorous gases, so that the malodorous gases are potential pollution hazard sources, once being emitted into the atmosphere, the malodorous gases tend to affect surrounding areas and affect the surrounding environment, and therefore the malodorous gases must be deodorized to reach the emission standard. The existing deodorization measures comprise an activated carbon adsorption method, a low-temperature plasma purification method, a biological method and a UV (ultraviolet) photolysis method, and although the existing deodorization measures can effectively purify the sewage odor, the existing deodorization measures still have a plurality of defects, such as: the purification means of the activated carbon adsorption method needs to replace new activated carbon after the saturation of the adsorption, and the replaced activated carbon after the saturation needs to be treated by dangerous waste by professional personnel, so the operation cost is high; the low-temperature plasma purification method has high one-time investment and potential safety hazard; the biological purification method needs to constantly put medicaments to keep the microbial activity, has high requirements on circulating water, and generates secondary pollutants such as sludge, sewage and the like; and the final UV photolysis method, wherein UV refers to the English abbreviation of Ultraviolet rays, the original English name of the UV is Ultraviolet, and due to the adoption of the lamp tubes which are distributed more, and under the closed box use state, an operator cannot detect or replace the lamp tubes in time, so that the purification efficiency cannot be ensured.
