在工業生產中，含硫化合物的排放是長期存在的環境與設備難題，生物脫硫技術借助微生物的代謝作用，為這類問題提供了高效且環保的解決方案。它突破了傳統脫硫工藝的局限，從源頭削減硫化物的危害，既降低了對生態環境的影響，又減少了設備損耗，成為化工、能源、冶金等行業可持續發展的重要支撐。

　　In industrial production, the emission of sulfur-containing compounds is a long-standing environmental and equipment challenge. Biological desulfurization technology, with the help of microbial metabolism, provides an efficient and environmentally friendly solution to such problems. It breaks through the limitations of traditional desulfurization processes, reduces the harm of sulfides from the source, reduces the impact on the ecological environment, and minimizes equipment losses, becoming an important support for the sustainable development of industries such as chemical, energy, and metallurgy.

　　解決硫化物廢氣的環境污染問題是生物脫硫的首要作用。工業廢氣中的硫化氫、二氧化硫等硫化物是酸雨形成的主要元兇，會酸化土壤和水體，破壞森林、農作物生長環境，損害建筑物表面。生物脫硫技術通過馴化的功能微生物，在反應器中將硫化物轉化為無害的單質硫或硫酸鹽，使廢氣中硫化物濃度從數千毫克 / 立方米降至數十毫克 / 立方米以下，遠低于排放標準。例如，處理化工企業含硫尾氣時，微生物能在常溫常壓下將硫化氫高效氧化，避免傳統燃燒法產生的二次污染，同時減少溫室氣體生成，從多維度降低對生態環境的負面影響。

　　The primary role of biological desulfurization is to solve the environmental pollution problem caused by sulfide waste gas. Sulfides such as hydrogen sulfide and sulfur dioxide in industrial waste gas are the main culprits of acid rain formation, which acidify soil and water bodies, damage forests and crop growth environments, and damage building surfaces. Biological desulfurization technology converts sulfides into harmless elemental sulfur or sulfate in a reactor through domesticated functional microorganisms, reducing the concentration of sulfides in exhaust gas from thousands of milligrams per cubic meter to below tens of milligrams per cubic meter, far below emission standards. For example, when dealing with sulfur-containing tail gas from chemical enterprises, microorganisms can efficiently oxidize hydrogen sulfide at room temperature and pressure, avoiding secondary pollution caused by traditional combustion methods and reducing greenhouse gas generation, thereby reducing the negative impact on the ecological environment from multiple dimensions.

　　解決設備腐蝕與能源浪費問題，可延長工業設施的使用壽命。含硫氣體具有強烈腐蝕性，會對管道、閥門、反應器等設備造成化學腐蝕，增加維護成本，甚至引發安全事故。生物脫硫技術去除硫化物后，氣體腐蝕性大幅降低，設備維護周期可延長 30% 以上。在能源生產領域，原料中的硫化物會導致燃燒設備的催化劑中毒失效，降低能源轉化效率，生物脫硫能將原料氣中硫化物脫除至 0.1ppm 以下，保障燃燒設備高效運行，提升能源利用效率 5%-10%。

　　Solving the problems of equipment corrosion and energy waste can extend the service life of industrial facilities. Sulfur containing gases have strong corrosiveness and can cause chemical corrosion to pipelines, valves, reactors, and other equipment, increase maintenance costs, and even lead to safety accidents. After removing sulfides using biological desulfurization technology, the gas corrosiveness is significantly reduced, and the equipment maintenance cycle can be extended by more than 30%. In the field of energy production, sulfides in raw materials can cause catalyst poisoning and failure in combustion equipment, reducing energy conversion efficiency. Biological desulfurization can remove sulfides from raw gas to below 0.1ppm, ensuring efficient operation of combustion equipment and improving energy utilization efficiency by 5% -10%.

　　解決傳統脫硫工藝的高能耗與二次污染問題，能降低工業運行成本。傳統脫硫方法多依賴化學藥劑，消耗大量原料，還產生廢渣、廢液等二次污染物，處理這些廢棄物需額外投入。生物脫硫以微生物代謝替代化學反應，無需高價藥劑，僅需提供微生物生長所需營養物質，運行成本比傳統工藝降低 30%-50%。同時，生物脫硫產生的副產物（如單質硫）可回收利用，成為化工原料，實現 “變廢為寶”，進一步抵消運行成本。

　　Solving the high energy consumption and secondary pollution problems of traditional desulfurization processes can reduce industrial operating costs. Traditional desulfurization methods rely heavily on chemical agents, consume a large amount of raw materials, and generate secondary pollutants such as waste residue and liquid, which require additional investment for processing. Biological desulfurization replaces chemical reactions with microbial metabolism, without the need for expensive chemicals, and only requires the provision of nutrients needed for microbial growth. The operating cost is reduced by 30% -50% compared to traditional processes. At the same time, the by-products generated by biological desulfurization (such as elemental sulfur) can be recycled and used as chemical raw materials, achieving the goal of "turning waste into treasure" and further offsetting operating costs.

　　解決復雜工況下的脫硫難題，可適應多樣化的含硫廢氣特性。工業廢氣中硫化物形態多樣，既有無機硫也有有機硫，且濃度波動大，傳統工藝適應性較差。生物脫硫系統通過構建復合微生物群落，不同菌種分工代謝不同類型硫化物，實現對混合硫廢氣的協同去除，尤其對低濃度、多組分含硫廢氣處理效果顯著。例如處理垃圾填埋場沼氣時，生物脫硫能通過微生物聯合作用將總硫去除率穩定在 95% 以上，且在氣體參數波動時仍保持高效運行。

　　Solving the desulfurization problem under complex working conditions can adapt to the diverse characteristics of sulfur-containing waste gases. There are various forms of sulfides in industrial waste gas, including both inorganic and organic sulfur, and the concentration fluctuates greatly. Traditional processes have poor adaptability. The biological desulfurization system achieves synergistic removal of mixed sulfur waste gas, especially for low concentration and multi-component sulfur-containing waste gas, by constructing a composite microbial community and dividing the metabolism of different types of sulfides among different bacterial strains. For example, when dealing with landfill gas, biological desulfurization can stabilize the total sulfur removal rate at over 95% through the combined action of microorganisms, and maintain efficient operation even when gas parameters fluctuate.

　　解決操作復雜與安全風險問題，能提升脫硫過程的穩定性。傳統脫硫工藝需要高溫高壓條件，操作參數控制嚴格，易出現設備堵塞等問題，且化學藥劑存在安全風險。生物脫硫在常溫常壓下運行，反應條件溫和，設備結構簡單，操作難度低，普通操作人員經短期培訓即可上崗。系統運行安全性高，適合在化工園區、人口密集區等對安全要求嚴苛的場所應用。

　　Solving operational complexity and safety risks can enhance the stability of the desulfurization process. Traditional desulfurization processes require high temperature and high pressure conditions, strict control of operating parameters, and are prone to equipment blockages, as well as safety risks associated with chemical agents. Biological desulfurization operates at room temperature and pressure, with mild reaction conditions, simple equipment structure, and low operational difficulty. Ordinary operators can take up their posts after short-term training. The system has high operational security and is suitable for application in places with strict safety requirements such as chemical parks and densely populated areas.

　　生物脫硫技術從環境、經濟、安全等多個維度解決了工業硫化物處理的痛點，隨著微生物馴化技術的進步，其脫硫效率與適應范圍不斷拓展，正逐步替代傳統工藝，為推動產業綠色轉型提供切實可行的技術路徑。

　　Biological desulfurization technology has solved the pain points of industrial sulfide treatment from multiple dimensions such as environment, economy, and safety. With the advancement of microbial domestication technology, its desulfurization efficiency and adaptability continue to expand, gradually replacing traditional processes and providing a practical and feasible technical path for promoting industrial green transformation.
