Description

Technical Field

[0001] This utility model relates to the field of biofilter technology, and in particular to a temperature and humidity control structure for a high-efficiency composite biofilter. Background Technology

[0002] Active microorganisms attached to porous, moist media use organic matter in waste gas as energy and nutrients for their life activities, growing, reproducing, and expanding their populations. In this process, they produce a large number of bio-enzyme catalysts. These microorganisms rely on these highly catalytically active bio-enzymes to degrade organic matter, converting it into simple inorganic substances such as CO2, H2O, or cellular components, thus treating the waste gas. For example, patent (CN206746282U) describes a VOC waste gas treatment device for a coal chemical industry wastewater pond. While this device uses a point-source emission mode and can achieve a removal rate of over 90% for gases such as hydrogen sulfide and ammonia, it cannot accurately detect the temperature and environmental information required for microbial adaptation in the biological filter, leading to reduced efficiency in waste gas treatment and affecting overall waste gas treatment efficiency.
