在環保要求日益嚴苛的當下，含硫廢氣、廢液的處理成為眾多工業領域的重要課題。生物脫硫塔作為生物脫硫技術的核心設備，憑借其綠色、高效的特性，在能源、化工、冶金等行業的脫硫環節中嶄露頭角。它以微生物的代謝活動為基礎，將含硫汙染物轉化為無害物質，為實現清潔生產和可持續發展提供了有力支撐。

In the increasingly stringent environmental requirements, the treatment of sulfur-containing waste gas and liquid has become an important issue in many industrial fields. As the core equipment of biological desulfurization technology, the biological desulfurization tower has emerged in the desulfurization process of energy, chemical, metallurgical and other industries due to its green and efficient characteristics. It is based on the metabolic activity of microorganisms, converting sulfur-containing pollutants into harmless substances, providing strong support for achieving clean production and sustainable development.

生物脫硫塔通常由塔體、填料層、布氣（液）裝置、噴淋係統、微生物培養係統和控製係統等部分組成。塔體一般采用圓柱形結構，由耐腐蝕材料製成，如玻璃鋼、不鏽鋼或特殊防腐塗層的碳鋼，以適應含硫物質的腐蝕環境。​

A biological desulfurization tower typically consists of a tower body, packing layer, gas (liquid) distribution device, spray system, microbial cultivation system, and control system. The tower body generally adopts a cylindrical structure and is made of corrosion-resistant materials, such as fiberglass, stainless steel, or carbon steel with special anti-corrosion coatings, to adapt to the corrosive environment of sulfur-containing substances. ​

填料層是生物脫硫塔的核心區域，它為微生物提供附著生長的表麵。常用的填料有塑料花環填料、陶瓷填料、彈性立體填料等。這些填料具有比表麵積大、孔隙率高、化學穩定性好的特點，能夠增加微生物與含硫物質的接觸麵積，提高脫硫效率。例如，塑料花環填料結構輕巧，不易堵塞，能有效促進氣 - 液 - 固三相之間的傳質與反應。​

The packing layer is the core area of the biological desulfurization tower, providing a surface for microorganisms to attach and grow. Common fillers include plastic flower wreath fillers, ceramic fillers, elastic three-dimensional fillers, etc. These fillers have the characteristics of large specific surface area, high porosity, and good chemical stability, which can increase the contact area between microorganisms and sulfur-containing substances and improve desulfurization efficiency. For example, plastic flower garland fillers have a lightweight structure, are not easily clogged, and can effectively promote mass transfer and reaction between the gas liquid solid phases. ​

布氣（液）裝置位於塔體底部，其作用是使含硫廢氣或廢液均勻分布在填料層底部，確保與微生物充分接觸。對於廢氣處理的生物脫硫塔，布氣裝置通過合理設計的氣孔或氣體分布器，將廢氣均勻分散；而處理廢液的脫硫塔，布液裝置則通過管道和噴頭，使廢液均勻噴淋在填料上。​

The gas (liquid) distribution device is located at the bottom of the tower, and its function is to evenly distribute sulfur-containing waste gas or liquid at the bottom of the packing layer, ensuring sufficient contact with microorganisms. For the biological desulfurization tower for waste gas treatment, the gas distribution device evenly disperses the waste gas through well-designed pores or gas distributors; The desulfurization tower for treating waste liquid and the liquid distribution device evenly spray the waste liquid onto the packing material through pipelines and nozzles. ​

噴淋係統用於向填料層噴灑營養液或洗滌液。營養液中含有微生物生長所需的碳源、氮源、磷源等營養物質，維持微生物的活性；洗滌液則用於清洗填料表麵，防止雜質和代謝產物積累導致填料堵塞，影響傳質效率。​

The sprinkler system is used to spray nutrient solution or washing solution onto the filling layer. The nutrient solution contains nutrients such as carbon, nitrogen, and phosphorus required for microbial growth, which maintain the activity of microorganisms; Washing solution is used to clean the surface of the packing material, preventing impurities and metabolites from accumulating and causing packing blockage, which affects mass transfer efficiency. ​

微生物培養係統負責培養和馴化高效脫硫微生物。該係統包括菌種儲存罐、培養基配製設備以及接種裝置等。通過篩選和培育適合特定含硫物質處理的微生物菌種，並在塔內創造適宜的生長環境，使微生物能夠快速繁殖並發揮脫硫作用。​

The microbial cultivation system is responsible for cultivating and domesticating efficient desulfurization microorganisms. The system includes strain storage tanks, culture medium preparation equipment, and inoculation devices. By screening and cultivating microbial strains suitable for specific sulfur-containing substance treatment, and creating a suitable growth environment inside the tower, microorganisms can rapidly reproduce and exert desulfurization effects. ​

控製係統則對生物脫硫塔的運行參數進行實時監測和調節，如溫度、pH 值、氣體流量、液體噴淋量等。通過傳感器采集數據，並將信息反饋給控製係統，一旦參數偏離設定範圍，係統會自動調節相關設備，確保脫硫塔穩定運行。

The control system monitors and adjusts the operating parameters of the biological desulfurization tower in real-time, such as temperature, pH value, gas flow rate, liquid spray rate, etc. By collecting data through sensors and providing feedback to the control system, once the parameters deviate from the set range, the system will automatically adjust the relevant equipment to ensure the stable operation of the desulfurization tower.

未來，生物脫硫塔的發展將朝著高效化、智能化和集成化方向邁進。通過基因工程、代謝工程等生物技術手段，培育更高效、更穩定的脫硫微生物菌種；利用先進的傳感器和控製技術，實現對脫硫塔運行參數的實時、精準調控，提高設備的自動化水平；將生物脫硫塔與其他處理技術集成，形成聯合脫硫工藝，提高處理效率和適應性，使其在更多領域得到廣泛應用，為環境保護和可持續發展做出更大貢獻。​

In the future, the development of biological desulfurization towers will move towards high efficiency, intelligence, and integration. Cultivate more efficient and stable desulfurization microbial strains through biotechnology methods such as genetic engineering and metabolic engineering; By utilizing advanced sensors and control technology, real-time and precise control of the operating parameters of the desulfurization tower can be achieved, improving the automation level of the equipment; Integrating biological desulfurization towers with other treatment technologies to form a joint desulfurization process, improving treatment efficiency and adaptability, and enabling them to be widely applied in more fields, making greater contributions to environmental protection and sustainable development. ​
