Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a biological deodorizing device for a sewage treatment plant. Background Art

[0002] The principle of biological deodorization process is to use the biodegradation of microorganisms to absorb and degrade odor substances to achieve the purpose of deodorization. The odor passes through the moist, porous and active microbial filter layer, and uses the adsorption, absorption and degradation functions of microbial cells on odorous substances. The microbial cells are small, have a large surface area, strong adsorption, and have diverse metabolic types. After adsorbing the odorous substances, they are decomposed into simple inorganic substances such as CO2, H2O, H2SO4, and HNO3. The biological filter method has high deodorization efficiency and is suitable for the treatment of large-volume and low-concentration waste gas.

[0003] In the prior art, a patent application with publication number CN 209554891U discloses a microbial purification and deodorization system, which includes: an air inlet channel, a microbial purification chamber, a negative pressure chamber, and an air outlet channel; an air inlet is formed at one end of the air inlet channel, and the other end is connected to the microbial purification chamber; the front chamber of the microbial purification chamber is filled with a first microbial filler, and the first composite deodorizing bacteria are attached to the first microbial filler; the rear chamber of the microbial purification chamber is separated from the front chamber by a hollow partition; the rear chamber is filled with a second microbial filler, and the second composite deodorizing bacteria are attached to the second microbial filler; the negative pressure chamber is located downstream of the microbial purification chamber and is connected thereto; a negative pressure fan is provided in the negative pressure chamber; an air outlet is formed at one end of the air outlet channel, and the other end is connected to the negative pressure chamber. The utility model collects the generated odor by negative pressure, and promotes the decomposition of ozone and other substances in the odor by microorganisms, which is conducive to the degradation of odor substances and the purification of air. However, in the process of odor treatment, the temperature of the odor after spraying is relatively low. If it directly enters the filter bed filtration area for biological deodorization, the deodorization effect is poor.

[0004] Therefore, the present application proposes a biological deodorization device for a sewage treatment plant. Utility Model Content
