Biological filtering equipment

Abstract

The invention discloses biological filtering equipment. The biological filtering equipment comprises four filtering towers and an air box, wherein each filtering tower comprises four filtering layers;each filtering layer comprises a filler carrying layer, a filler and an inoculating material; the air is sucked by an induced air fan via an air intake channel, passes through all filtering towers, and is exhausted out via an air exhaust channel. The biological filtering equipment has the advantages that the ozone pollution due to failure of single filtering layer can be reduced; by arranging themultiple filtering layers, the air drag can be favorably balanced, the contact between microorganisms and harmful gases is enhanced, and the deodorizing effect is thorough; the biological filtering equipment can be applied to the absorption of aerobic fermenting ozone.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a biological filter device. Background technique [0002] At present, the treatment of kitchen waste is a very important topic in the field of waste treatment. Kitchen waste includes leftovers, leftovers, eggshells, etc. Because of its organic matter, it is often fermented and decomposed by microorganisms under aerobic conditions through a kitchen waste machine, and finally produces compost. The aerobic fermentation process is accompanied by the generation of odor (mainly ammonia, hydrogen sulfide, methyl mercaptan, amines, etc.), therefore, the kitchen waste machine is generally equipped with a deodorization equipment to remove the odor. However, in the prior art, since most of the deodorizing filter equipment on the market is a filter equipment with a single filter layer, when the filter layer is abnormal, the entire filter system will fail, and the polluted ga...

AI Technical Summary

Problems solved by technology

However, in the prior art, since most of the deodorizing filter equipment on the market is a filter equipment with a single filter layer, when the filter layer is abnormal, the entire filter system will fail, and the polluted gas will be discharged outside the kitchen waste machine, causing personnel unwell

In addition, the use of a single filter layer has problems such as large wind resistance, small contact area between fillers and harmful gases, and low filtration efficiency.
