A kind of biological filter deodorization system and method for treating peculiar smell

Abstract

The invention belongs to the field of biological deodorization, and in particular relates to a biological filter deodorization system and a method for treating peculiar smell. The biological filter deodorization system includes a biological filter; the biological filter includes a washing area and a filtering area, and the washing The area is vertically arranged into four layers, which are spray layer, biological filler layer, air distribution layer, and water storage layer in sequence; the filtering area is equal to the washing area, and the odor passes through the washing area and the filtering area from bottom to top. The odor that passes through the washing area passes through the filter area through the collection pipeline, and the standard gas is discharged from the filter area; the invention fully purifies the odor molecules in the odor, prevents the pollution of the atmosphere and the surrounding air, and is suitable for popularization and application; The complex odor has strong adaptability and adapts to the odor concentration with a large fluctuation range, and the overall pressure loss of the packing layer in the biological filter is less than 1500Pa, and the normal service life is 25 years.

Description

technical field [0001] The invention belongs to the field of biological deodorization, and particularly relates to a biological filter tank deodorization system and a method for treating peculiar smell. Background technique [0002] At present, the methods in the art for treating odor generated by sewage treatment plants mainly include biological methods, activated carbon adsorption methods, chemical washing methods, plasma methods, and the like. Among them, the biological method is widely used in the treatment of malodorous gas in urban sewage and tannery sewage due to its advantages of less secondary pollution, low operating cost, and convenient operation and maintenance. The principle of biological deodorization is to use microorganisms to absorb malodorous substances in the microorganisms themselves and degrade them through the metabolic activities of microorganisms. Existing biological deodorization devices usually include biological washing towers, biological filterin...

AI Technical Summary

Problems solved by technology

[0003] 1) The air distribution is not uniform, and it is easy to produce a short flow dead zone;

[0004] 2) The pollutant removal load packing layer varies greatly along the process and is easy to harden;

[0005] 3) The gas-liquid mass transfer effect is poor

The current wastewater odor treatment system is relatively simple, and the odor is mostly eliminated by adding a large amount of chemicals. The cost is high, and a large amount of secondary pollution will be generated, which is not conducive to popularization and application.

[0008] And the deodorizing effect of existing biological filter is also limited, therefore, how to improve the deodorizing effect of biological filter is the research direction of those skilled in the art
