传统脱硫工艺离不开大罐大罐的化学药剂——胺法需要定期补充胺液，氧化铁干法需要频繁更换脱硫剂，湿法氧化需要持续投加催化剂。生物脱硫技术的出现，正在将这场“化学战”变成“生物战”——用细菌取代药罐，用微生物代谢取代化学反应。

The traditional desulfurization process cannot do without large tanks of chemical agents - amine method requires regular replenishment of amine solution, iron oxide dry method requires frequent replacement of desulfurizer, and wet oxidation requires continuous addition of catalyst. The emergence of biological desulfurization technology is turning this "chemical war" into a "biological war" - replacing medicine cans with bacteria and chemical reactions with microbial metabolism.

生物脱硫的工艺核心在于一个精巧的循环系统。以沼气生物脱硫为例，其工艺通常包含洗涤塔吸收、生物反应器转化和硫沉淀分离三个核心步骤。含硫化氢的沼气首先进入洗涤塔，与碱性循环液逆流接触，硫化氢被吸收形成硫氢根离子；富含硫化物的循环液随后进入生物反应器，在硫氧化菌的催化下被氧化为单质硫；非常后通过沉淀分离系统将硫磺从循环液中分离出来，净化后的循环液返回洗涤塔继续吸收。硫化氢去除率高达99.5%，产物硫磺可作为化肥原料。

The core of biological desulfurization process lies in a sophisticated circulation system. Taking biogas biological desulfurization as an example, its process usually includes three core steps: scrubbing tower absorption, bioreactor conversion, and sulfur precipitation separation. The biogas containing hydrogen sulfide first enters the washing tower and comes into counter current contact with the alkaline circulating liquid, where hydrogen sulfide is absorbed to form sulfide ions; The circulating liquid rich in sulfides then enters the bioreactor and is oxidized to elemental sulfur under the catalysis of sulfur oxidizing bacteria; Finally, sulfur is separated from the circulating liquid through a precipitation separation system, and the purified circulating liquid is returned to the washing tower for further absorption. The removal rate of hydrogen sulfide is as high as 99.5%, and the product sulfur can be used as a fertilizer raw material.

生物脱硫的工艺优势体现在多个维度。能耗优势——整个反应在常温常压下进行，无需加热加压，运行能耗远低于化学法。环保优势——不产生二次污染，主要产物是单质硫，可实现硫资源的回收利用。成本优势——虽然前期建设成本较高，但运行成本远低于干法和湿法脱硫。操作优势——系统启动时间快，工艺稳定，操作简单。

The technological advantages of biological desulfurization are reflected in multiple dimensions. Energy consumption advantage - the entire reaction is carried out at room temperature and pressure, without the need for heating and pressure, and the operating energy consumption is much lower than that of chemical methods. Environmental advantages - no secondary pollution is generated, the main product is elemental sulfur, which can achieve the recycling and utilization of sulfur resources. Cost advantage - Although the initial construction cost is relatively high, the operating cost is much lower than that of dry and wet desulfurization. Operational advantages - fast system startup time, stable process, and simple operation.

在产业应用方面，生物脱硫正从实验室走向广阔的市场。国外已有较成熟的沼气生物脱硫集成技术，主要包括荷兰帕克公司的壳牌-帕克工艺和奥地利英环生物滤池脱硫工艺等。国内的生物脱硫技术虽然起步较晚，但正在加速追赶。山西德远净能、唐山绿源、山东恒能等一批国内企业已开发出具有自主知识产权的沼气生物脱硫系统。山东蓝绿青环保等专业公司还具备了生物脱硫专用营养盐的生产能力，可整体配套生物脱硫项目需求。

In terms of industrial applications, biological desulfurization is moving from the laboratory to the vast market. There are already mature integrated technologies for biogas biological desulfurization abroad, mainly including the Shell Parker process of the Dutch company Parker and the desulfurization process of the Austrian company Yinghuan Biological Filter. Although the domestic biological desulfurization technology started relatively late, it is accelerating to catch up. A group of domestic enterprises such as Shanxi Deyuan Clean Energy, Tangshan Lvyuan, and Shandong Hengneng have developed biogas biological desulfurization systems with independent intellectual property rights. Shandong Blue Green Green Environmental Protection and other professional companies also have the production capacity of specialized nutrients for biological desulfurization, which can meet the overall needs of biological desulfurization projects.

生物脱硫技术仍在持续进化。研究者正在深入探索多硫化物介导的硫循环机制，试图通过调控生物质浓度、pH和氧化还原电位等关键参数，进一步提升单质硫的选择性和分离效率。从“化学药罐”到“细菌工厂”，生物脱硫正在用微生物的智慧，重新定义工业气体净化的技术范式。

Biological desulfurization technology is still evolving. Researchers are exploring the sulfur cycling mechanism mediated by polysulfides, attempting to further enhance the selectivity and separation efficiency of elemental sulfur by regulating key parameters such as biomass concentration, pH, and redox potential. From "chemical tanks" to "bacterial factories", biological desulfurization is using the wisdom of microorganisms to redefine the technological paradigm of industrial gas purification.
