在環保技術日新月異的今天，生物脫硫塔作為一種創新的廢氣處理裝置，正逐步成為工業領域實現綠色生產的關鍵設備。其核心優勢在于利用自然界的微生物力量，以溫和、高效的方式去除廢氣中的硫化物，為化工、電力、冶金等行業提供了可持續的廢氣治理方案。

　　In today's rapidly advancing environmental technology, biological desulfurization towers, as an innovative waste gas treatment device, are gradually becoming a key equipment for achieving green production in the industrial field. Its core advantage lies in utilizing the microbial power of nature to remove sulfides from waste gas in a gentle and efficient manner, providing sustainable waste gas treatment solutions for industries such as chemical, power, and metallurgy.

　　一、微生物的奇妙轉化

　　1、 The wonderful transformation of microorganisms

　　生物脫硫塔的工作原理，本質上是一場微觀世界的“硫元素轉化秀”。在塔內，棲息著經過精心篩選與馴化的微生物群落，它們以硫化氫（H?S）、二氧化硫（SO?）等含硫氣體為“食物”，通過一系列生化反應，將這些有害物質轉化為無害的硫酸鹽或單質硫。

　　The working principle of a biological desulfurization tower is essentially a "sulfur element transformation show" in the microscopic world. Inside the tower, there is a carefully screened and domesticated microbial community that feeds on sulfur-containing gases such as hydrogen sulfide (H? S) and sulfur dioxide (SO ?). Through a series of biochemical reactions, these harmful substances are converted into harmless sulfates or elemental sulfur.

　　這一過程主要分為兩個階段：吸附與氧化。當含硫廢氣進入生物脫硫塔時，首先與塔內填充的生物填料接觸。這些填料表面附著著大量的微生物菌膜，它們能夠迅速吸附廢氣中的硫化物分子。隨后，在微生物分泌的酶的作用下，硫化物被逐步氧化。例如，硫化氫首先被氧化為硫元素，進而可能被進一步氧化為硫酸鹽，最終以穩定的形態存在于循環液中，或通過后續處理實現資源化利用。

　　This process is mainly divided into two stages: adsorption and oxidation. When sulfur-containing waste gas enters the biological desulfurization tower, it first comes into contact with the biological packing material filled inside the tower. These fillers have a large amount of microbial biofilm attached to their surfaces, which can quickly adsorb sulfide molecules in exhaust gas. Subsequently, under the action of enzymes secreted by microorganisms, sulfides are gradually oxidized. For example, hydrogen sulfide is first oxidized to sulfur element, and may then be further oxidized to sulfate, ultimately existing in a stable form in the circulating liquid or being utilized for resource utilization through subsequent processing.

　　二、氣液固三相的協同作用

　　2、 The synergistic effect of gas-liquid solid three-phase system

　　生物脫硫塔的設計巧妙地利用了氣液固三相的協同作用，以確保脫硫過程的高效進行。廢氣作為氣相，在塔內自下而上流動；循環液作為液相，通過噴淋系統均勻分布，形成液膜，既為微生物提供了濕潤的生長環境，又促進了氣液之間的傳質；而生物填料則作為固相，為微生物提供了附著生長的載體，同時增大了氣液接觸面積。

　　The design of the biological desulfurization tower cleverly utilizes the synergistic effect of gas, liquid, and solid phases to ensure the efficient operation of the desulfurization process. The exhaust gas flows from bottom to top in the tower as a gas phase; Circulating liquid, as a liquid phase, is uniformly distributed through a spray system to form a liquid film, providing a moist growth environment for microorganisms and promoting mass transfer between gas and liquid; And biological fillers act as solid phases, providing a carrier for microbial attachment and growth, while increasing the gas-liquid contact area.

　　在塔內，廢氣中的硫化物首先溶解于循環液中，形成含硫的離子或分子。隨后，這些含硫物質通過擴散作用到達微生物菌膜表面，被微生物攝取并進入細胞內部進行代謝。代謝過程中產生的能量和中間產物，進一步驅動了微生物的生長與繁殖，形成了良性循環。

　　In the tower, sulfides in the exhaust gas first dissolve in the circulating liquid, forming sulfur-containing ions or molecules. Subsequently, these sulfur-containing substances reach the surface of microbial membranes through diffusion, are taken up by microorganisms, and enter the interior of cells for metabolism. The energy and intermediate products generated during the metabolic process further drive the growth and reproduction of microorganisms, forming a virtuous cycle.

　　三、智能調控與穩定運行

　　3、 Intelligent regulation and stable operation

　　為了確保生物脫硫塔的穩定運行和高效脫硫，系統配備了先進的智能調控裝置。這些裝置能夠實時監測廢氣中的硫化物濃度、循環液的pH值、溫度等關鍵參數，并根據監測結果自動調節噴淋量、營養液投加量等操作變量。

　　In order to ensure the stable operation and efficient desulfurization of the biological desulfurization tower, the system is equipped with advanced intelligent control devices. These devices are capable of real-time monitoring of key parameters such as sulfide concentration in exhaust gas, pH value of circulating liquid, temperature, etc., and automatically adjusting operational variables such as spray volume and nutrient solution dosage based on monitoring results.

　　例如，當廢氣中的硫化物濃度升高時，智能調控系統會自動增加噴淋量，以提供更多的循環液與廢氣接觸，從而提高脫硫效率。同時，系統還會根據循環液的pH值變化，適時投加堿性或酸性營養液，以維持微生物生長的最佳環境。

　　For example, when the concentration of sulfides in the exhaust gas increases, the intelligent control system will automatically increase the spray amount to provide more circulating liquid in contact with the exhaust gas, thereby improving the desulfurization efficiency. At the same time, the system will also add alkaline or acidic nutrient solutions in a timely manner based on changes in the pH value of the circulating liquid to maintain the optimal environment for microbial growth.

　　四、綠色循環與資源回收

　　4、 Green Recycling and Resource Recovery

　　生物脫硫塔不僅實現了廢氣的凈化處理，還開創了綠色循環與資源回收的新模式。在脫硫過程中產生的硫酸鹽或單質硫，經過進一步處理，可以轉化為有價值的化工原料，如硫酸、硫磺等。這些產品可以回用于生產流程，或作為副產品出售，從而實現廢物的資源化利用。

　　The biological desulfurization tower not only achieves the purification treatment of exhaust gas, but also creates a new model of green circulation and resource recovery. The sulfate or elemental sulfur generated during the desulfurization process can be further processed and converted into valuable chemical raw materials such as sulfuric acid and sulfur. These products can be reused in the production process or sold as by-products, thereby achieving the resource utilization of waste.

　　此外，生物脫硫塔的運行過程中無需添加化學藥劑，避免了二次污染的產生。同時，微生物在代謝過程中產生的能量，部分可以用于維持系統的自養運行，進一步降低了能耗和運行成本。

　　In addition, there is no need to add chemical agents during the operation of the biological desulfurization tower, which avoids the generation of secondary pollution. Meanwhile, some of the energy generated by microorganisms during metabolic processes can be used to maintain the self-sustaining operation of the system, further reducing energy consumption and operating costs.
