Abstract

The invention provides a composite biological deodorizing system and method for processing large amount high density stink. The system includes a deodorizing tower and a circulation liquid pool. A gas distribution layer, a circulation liquid collection tank, a biological washing layer, a biological trickling filter layer, a biological filter layer and a chimney are arranged in order from bottom to top in the deodorizing tower. The biological washing layer and the biological trickling filter layer are provided with nozzles and corresponding biological filling materials. The biological filter layer is provided with the corresponding biological filling materials and biological flora is inoculated. Stink ingredients let in the deodorizing tower are degraded and purified by the circulation liquid in the circulation liquid pool through a shower pipeline, and then the circulation liquid flows back to the circulation liquid pool for treatment. In this way, by circulation use, the high density exhaust gas with various kinds of stink mixed can be processed; simultaneously a deodorizing program is simplified, the operation cost of the devices is reduced, and the efficiency for purifying exhaust gas is improved.

Description

technical field [0001] The invention relates to a process for treating high-volume and high-concentration odor in biological environment engineering. More specifically, organically combine biological washing deodorization, biological trickling deodorization, biological filtration deodorization, circulating fluid aeration treatment and compound deodorizing bacteria liquid, and adopt different filler biological deodorization processes in each deodorization section . Background technique [0002] Odor pollution problems will occur in the production processes of landfills, garbage treatment plants, feces treatment stations, sewage sludge treatment plants, petrochemical, biopharmaceutical, leather, paint and other enterprises. In addition, urban waste landfills and polluted rivers also continue to emit some putrid odors, becoming one of the important sources of pollution in the city. These malodorous gas components include gases of malodorous substances such as hydrogen sulfide...
