Efficient biological deodorization equipment

Abstract

The invention discloses efficient biological deodorization equipment. The efficient biological deodorization equipment comprises a dripping filter (1), wherein the dripping filter (1) is successively provided with a demister (9), a first spray thrower (71), a first porous aggregate bed layer (61), a second spray thrower (72), a second porous aggregate bed layer (62) and a gas diffuser (5) from top to bottom; the gas diffuser (5) is communicated with an air blower (2), and the bottom of the dripping filter (1) is respectively communicated with a liquid inlet of a fungus liquid tank (3) and a liquid inlet of a first water pump (41); a liquid outlet of the fungus liquid tank (3) is communicated with the liquid inlet of the first water pump (41), a liquid outlet of the first water pump (41) is respectively communicated with the liquid inlet of the first spray thrower (71) and a liquid inlet of second spray thrower (72), and the fungus liquid tank (3) is internally provided with deodorization fungus liquid. The efficient biological deodorization equipment provided by the embodiment of the invention has the advantages of improving the growth rate of a biological membrane, shortening the growth cycle of the biological membrane, improving the deodorization capacity, and effectively preventing the porous aggregate bed layer from being blocked.

Description

technical field [0001] The invention relates to the technical field of deodorization, in particular to a high-efficiency biological deodorization equipment. Background technique [0002] Odor from sewage treatment plants and garbage disposal sites has always been one of the main sources of air pollution; the main components of these odors include ammonia, hydrogen sulfide, and volatile organic compounds (Volatile Organic Compounds, VOCs), so these odors Gas is highly toxic, highly corrosive, and difficult to remove. [0003] At present, sewage treatment plants and garbage disposal sites mainly use biological deodorization method to remove odor; biological deodorization method mainly uses domesticated microorganisms to decompose malodorous substances into carbon dioxide and water, or other recyclables, so as to achieve deodorization. Purpose. In the prior art, sewage treatment plants and garbage disposal sites mainly carry out biological deodorization in trickling filter to...

AI Technical Summary

Problems solved by technology

In the prior art, sewage treatment plants and garbage disposal sites mainly carry out biological deodorization in trickling filter towers. A biofilm is formed on the packing bed, so that the biofilm can be used for deodorization; however, the nutrient solution can provide limited nutrients for the growth of microorganisms, and the nutrient concentration of the nutrient solution entering the trickling filter tower at different times is not uniform, so the biofilm The growth rate is slow, the growth cycle is long, the effective degradation space of the odor is small, and the deodorization ability is weak; at the same time, the local nutrient solution concentration is too high, which may also cause the through-hole blockage of the porous packing bed
