Mushroom bran packing biological deodorizing tower

Abstract

The invention provides a mushroom bran packing biological deodorizing tower, which mainly comprises: a multi-pore plate mounted inside, wherein the mushroom bran packing is filled above the multi-pore hole, and a spraying device is arranged above the mushroom bran packing; a gas inlet arranged at the position at the side of the deodorizing tower and placed below the multi-pore plate; a gas outlet arranged at the position at the side of the deodorizing tower and placed above the spraying device; and a draining port provided at the bottom of the deodorizing tower. Compared with existing deodorizing packing, the mushroom bran packing used in the deodorizing tower provided by the invention has a wide and cheap resource, and is simple to process, as well as reducing the cost; the mushroom bran packing used in the invention has the characteristics of loose texture, and difficulty in compacting. By using the deodorizing tower, more than 85% H2S and 90%NH3 can be removed within 12 hours, thus, the deodorizing tower can be widely applied to process waste gas in composting plants and refuse processing plants.

Description

technical field [0001] The invention belongs to the technical field of waste treatment, and in particular relates to a biological deodorization tower using fungus chaff as a raw material and rice husk as a conditioning agent. Background technique [0002] Odor pollution has caused great harm to the ecological environment and human health, and has received extensive attention worldwide. Traditional treatment techniques are mainly physical and chemical methods, and biological methods have gradually become one of the main methods for purifying odorous substances. Biological method is the process of using microorganisms to degrade or convert malodorous substances into odorless or low-odor substances. Compared with physical and chemical treatment methods, biological deodorization requires almost no addition of chemical agents, and because it operates at normal temperature and pressure, the waste of energy is relatively low, and no secondary pollution occurs. Due to its low cost...

AI Technical Summary

Problems solved by technology

With the continuous development of my country's edible fungus industry, a large amount of fungus chaff has accumulated, which not only pollutes the surrounding water and soil, but also seriously interferes with the healthy operation of the edible fungus industry.

[0004] At present, some researchers have carried out research on the use of fungus chaff to produce feed and fertilizer, but there is no report on the study of using fungus chaff as a raw material and mixing rice husks to prepare biological deodorization fillers
