Deodorizing device and deodorizing method using same

Abstract

The invention belongs to the field of biological deodorizing, and discloses a deodorizing device and a deodorizing method using the same. The deodorizing device comprises a casing, a spraying assembly, a filler layer, an air distribution layer, a liquid storage layer, an air inlet and an air exhaust port, wherein the spraying assembly, the filler layer, the air distribution layer and the liquid storage layer are positioned in the casing and are sequentially arranged along the height direction of the casing from top to bottom; the air inlet is arranged on the casing and is communicated with the air distribution layer; the air exhaust port is arranged at the top part of the casing; the liquid storage layer comprises a liquid inlet and a liquid outlet, and the liquid outlet of the liquid storage layer is communicated together with the spraying assembly through a connecting pipeline; a circulating pump is arranged on the connecting pipeline, and the liquid inlet of the liquid storage layer is communicated with an external liquid source; the filler layer comprises microorganisms for deodorizing; when the liquid inlet of the liquid storage layer is closed, and the liquid outlet of the liquid storage layer, the air inlet of the circulating pump and the air exhaust port are opened, the deodorizing device starts a circulating, spraying and deodorizing mode. The deodorizing device disclosed by the invention can treat ozone containing high concentration of hydrogen sulfide gas at high efficiency.

Description

technical field [0001] The invention relates to the field of biological deodorization, in particular to a deodorization device and a deodorization method using the same. Background technique [0002] Biological deodorization mainly uses microorganisms to deodorize, transforms odorous substances through microbial metabolism, and effectively decomposes and removes target pollutants to achieve the purpose of odor control. Because biological deodorization is more targeted and more economical and environmentally friendly, the treatment of odor by biological deodorization has been widely used in various industries, especially in the treatment of odor generated by municipal sewage. [0003] At present, the existing biological deodorization method is mainly the biological filter method. The biofilter method is mainly based on the filled biofilter. At present, the filled biofilter technology in the market is mainly based on the biofiltration method and the biotrickling method. The ...

AI Technical Summary

Problems solved by technology

In the existing sewage odor treatment, the concentration of odorous substances contained in the odor produced by some sewage plants is relatively low, and the existing biological filtration method and biological trickling filtration method can still meet the deodorization requirements , but for some sewage plants, due to changes in water quality and water volume, the concentration of odor is very high. Under certain working conditions, the concentration of hydrogen sulfide in the odor can be as high as 500mg / m 3 At this time, the existing biofiltration and biotrickling filtration methods suitable for low-concentration odor treatment cannot meet the deodorization requirements
