在工业生产中，含硫化合物的排放是长期存在的环境与设备难题，生物脱硫技术借助微生物的代谢作用，为这类问题提供了高效且环保的解决方案。它突破了传统脱硫工艺的局限，从源头削减硫化物的危害，既降低了对生态环境的影响，又减少了设备损耗，成为化工、能源、冶金等行业可持续发展的重要支撑。

　　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.

　　解决硫化物废气的环境污染问题是生物脱硫的首要作用。工业废气中的硫化氢、二氧化硫等硫化物是酸雨形成的主要元凶，会酸化土壤和水体，破坏森林、农作物生长环境，损害建筑物表面。生物脱硫技术通过驯化的功能微生物，在反应器中将硫化物转化为无害的单质硫或硫酸盐，使废气中硫化物浓度从数千毫克 / 立方米降至数十毫克 / 立方米以下，远低于排放标准。例如，处理化工企业含硫尾气时，微生物能在常温常压下将硫化氢高效氧化，避免传统燃烧法产生的二次污染，同时减少温室气体生成，从多维度降低对生态环境的负面影响。

　　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.

　　解决设备腐蚀与能源浪费问题，可延长工业设施的使用寿命。含硫气体具有强烈腐蚀性，会对管道、阀门、反应器等设备造成化学腐蚀，增加维护成本，甚至引发安全事故。生物脱硫技术去除硫化物后，气体腐蚀性大幅降低，设备维护周期可延长 30% 以上。在能源生产领域，原料中的硫化物会导致燃烧设备的催化剂中毒失效，降低能源转化效率，生物脱硫能将原料气中硫化物脱除至 0.1ppm 以下，保障燃烧设备高效运行，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%.

　　解决传统脱硫工艺的高能耗与二次污染问题，能降低工业运行成本。传统脱硫方法多依赖化学药剂，消耗大量原料，还产生废渣、废液等二次污染物，处理这些废弃物需额外投入。生物脱硫以微生物代谢替代化学反应，无需高价药剂，仅需提供微生物生长所需营养物质，运行成本比传统工艺降低 30%-50%。同时，生物脱硫产生的副产物（如单质硫）可回收利用，成为化工原料，实现 “变废为宝”，进一步抵消运行成本。

　　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.

　　解决复杂工况下的脱硫难题，可适应多样化的含硫废气特性。工业废气中硫化物形态多样，既有无机硫也有有机硫，且浓度波动大，传统工艺适应性较差。生物脱硫系统通过构建复合微生物群落，不同菌种分工代谢不同类型硫化物，实现对混合硫废气的协同去除，尤其对低浓度、多组分含硫废气处理效果显著。例如处理垃圾填埋场沼气时，生物脱硫能通过微生物联合作用将总硫去除率稳定在 95% 以上，且在气体参数波动时仍保持高效运行。

　　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.

　　解决操作复杂与安全风险问题，能提升脱硫过程的稳定性。传统脱硫工艺需要高温高压条件，操作参数控制严格，易出现设备堵塞等问题，且化学药剂存在安全风险。生物脱硫在常温常压下运行，反应条件温和，设备结构简单，操作难度低，普通操作人员经短期培训即可上岗。系统运行安全性高，适合在化工园区、人口密集区等对安全要求严苛的场所应用。

　　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.

　　生物脱硫技术从环境、经济、安全等多个维度解决了工业硫化物处理的痛点，随着微生物驯化技术的进步，其脱硫效率与适应范围不断拓展，正逐步替代传统工艺，为推动产业绿色转型提供切实可行的技术路径。

　　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.
