Description

Technical Field

[0001] This utility model relates to the field of biological deodorization technology, specifically to a deodorization device for removing ammonia and hydrogen sulfide. Background Technology

[0002] Removing ammonia and hydrogen sulfide, and achieving deodorization, are key requirements in environmental governance and industrial production, primarily applied in wastewater treatment, livestock farming, and waste disposal. Ammonia (NH3) has a pungent odor, is readily soluble in water to form an alkaline solution, and is corrosive to the respiratory tract and equipment. Hydrogen sulfide (H2S) has a rotten egg smell, is highly toxic, and excessive concentrations can endanger human health. Both often mix with other volatile organic compounds (VOCs) to form complex odors, requiring comprehensive treatment.

[0003] CN216537810U discloses a microbial deodorization device for removing ammonia and hydrogen sulfide. This device includes a deodorization chamber, inlet and outlet gas pipelines, a circulating water system, and a detector. It works by first removing ammonia and hydrogen sulfide from the air through thorough contact between a deodorizing bacterial solution and the air containing ammonia and hydrogen sulfide. Then, ammonia- and desulfurizing microbial strains are used to efficiently degrade the ammonia and hydrogen sulfide. The degraded solution continues to exchange with air containing ammonia and hydrogen sulfide, cyclically degrading them. This microbial deodorization device can completely degrade ammonia and hydrogen sulfide in the air without secondary pollution. Furthermore, the device is small in size and requires little floor space, making it easy to install and use indoors. The immobilized bacterial agent can be reused, resulting in low cost.

[0004] The problem with the aforementioned microbial deodorization device for removing ammonia and hydrogen sulfide is that:

[0005] 1. Static spraying has limited gas-liquid contact efficiency.

[0006] The device uses a fixed spray or static packing layer, resulting in insufficient contact between the gas and the deodorizing liquid, leading to low reaction efficiency, and is particularly ineffective in treating high-concentration or high-flow-rate waste gas.

[0007] Second, recycling of bacterial solutions can easily lead to secondary contamination or bacterial colony failure.

[0008] Relying on the degradation of circulating bacterial solution, the activity of the bacterial solution decreases after long-term use, which may lead to the accumulation of metabolic products, causing secondary pollution or requiring frequent replacement of bacterial agents, resulting in high maintenance costs. Utility Model Content
