生物除臭的工作原理主要涉及恶臭气体的溶解、恶臭物质的吸附以及恶臭物质的生物降解三个阶段。恶臭气体的溶解过程。当废气与水接触时,污染物溶于水,由气相转为液相。恶臭物质的吸附过程。水溶液中的恶臭成分被微生物吸附,从水中转移至微生物体内,水被再生复原,而被吸附的有机物经生物转化被微生物摄入体内。
恶臭物质的生物降解过程。进入微生物细胞的恶臭成分作为营养物质被分解和利用,其他有机物成分被氧化分解为二氧化碳和水。含硫还原性成分被氧化为硫,由出气口排出。
Biological odor removal primarily involves three stages: the dissolution of odorous gases, the adsorption of odorous substances, and the biodegradation of odorous substances. The dissolution process of odorous gases occurs when exhaust gas comes into contact with water, where pollutants dissolve in water, transitioning from the gas phase to the liquid phase. The adsorption process of odorous substances involves the adsorption of odorous components in the aqueous solution by microorganisms, transferring from the water to the interior of the microorganisms, allowing the water to be regenerated, while the adsorbed organic matter is transformed and taken up by the microorganisms through biological processes. The biodegradation process of odorous substances refers to the breakdown and utilization of odorous components that enter the microbial cells as nutrients. Other organic components are oxidized and decomposed into carbon dioxide and water. Sulfurous reduction components are oxidized to sulfur and expelled through the outlet.
