Description

Technical Field

[0002] Aerobic fermentation is a technology that uses microorganisms to degrade and treat waste, and the presence of oxygen is required in the process. The waste gas composition is mainly composed of a variety of gases, the most common of which are carbon dioxide (CO2), aqueous vapor (H2O) and nitrogen (N2). In addition, there are small amounts of oxygen (O2), methane (CH4) and some impurity gases. Conventional methods for treating malodorous gases include combustion, oxidation, absorption, adsorption, neutralization and biological methods.

[0003] The commonly used deodorization method at present is biological deodorization, that is, under aerobic conditions, the metabolic activity of aerobic microorganisms is used to convert odorous gases into odorless gases. However, after the odor is treated by the existing microbial deodorization device, the aqueous solution layer on the surface of the bacteria will affect the mass transfer rate for substances with low solubility in aqueous solution, and the odor and microorganisms are not in sufficient contact, which will lead to reduced treatment efficiency, so that odor still remains in the exhausted gas, causing pollution to the environment, and it is difficult to completely deodorize the exhaust gas in a short time by relying on a single deodorization method.
