在全球對環境保護和可持續發展日益重視的大背景下，能源生產(chan) 與(yu) 利用過程中的汙染控製成為(wei) 關(guan) 鍵議題。其中，含硫化合物的排放控製尤為(wei) 重要，因其不僅(jin) 會(hui) 導致酸雨等環境問題，還會(hui) 對人體(ti) 健康造成嚴(yan) 重威脅。生物脫硫技術作為(wei) 一種新興(xing) 的綠色環保技術，正逐漸嶄露頭角，為(wei) 解決(jue) 硫汙染問題提供了創新且高效的必威betway东盟体育。​

Against the backdrop of increasing global attention to environmental protection and sustainable development, pollution control in the process of energy production and utilization has become a key issue. Among them, the emission control of sulfur-containing compounds is particularly important, as they not only cause environmental problems such as acid rain, but also pose a serious threat to human health. Biological desulfurization technology, as an emerging green environmental protection technology, is gradually emerging and providing innovative and efficient solutions to solve sulfur pollution problems. ​

技術誕生背景​

Background of Technology Birth

傳(chuan) 統的脫硫方法，如物理脫硫和化學脫硫，雖在一定程度上能夠脫除燃料或廢氣中的硫，但存在諸多局限性。物理脫硫往往難以徹底去除細微的含硫顆粒，且對設備要求較高；化學脫硫則可能產(chan) 生二次汙染，同時需要消耗大量的化學試劑，成本高昂。隨著環保法規的日益嚴(yan) 格以及人們(men) 對清潔能源需求的不斷增加，開發一種更加高效、環保且經濟的脫硫技術迫在眉睫，生物脫硫技術應運而生。​

Traditional desulfurization methods, such as physical desulfurization and chemical desulfurization, can to some extent remove sulfur from fuel or exhaust gas, but they have many limitations. Physical desulfurization is often difficult to completely remove fine sulfur-containing particles and requires high equipment requirements; Chemical desulfurization may generate secondary pollution and require a large amount of chemical reagents, resulting in high costs. With the increasingly strict environmental regulations and the growing demand for clean energy, it is urgent to develop a more efficient, environmentally friendly, and economical desulfurization technology, and biological desulfurization technology has emerged. ​

工作原理深度剖析​

In depth analysis of working principle

生物脫硫技術主要基於(yu) 微生物的代謝活動來實現硫的脫除。在自然界中，存在著一些特殊的微生物，如氧化亞(ya) 鐵硫杆菌、排硫硫杆菌等，它們(men) 具有獨特的代謝途徑，能夠利用含硫化合物作為(wei) 能源物質進行生長和繁殖。以煤炭生物脫硫為(wei) 例，這些微生物可以將煤炭中的黃鐵礦（FeS₂）氧化為(wei) 硫酸亞(ya) 鐵（FeSO₄）和硫酸（H₂SO₄），反應過程如下：首先，微生物將 FeS₂中的二價(jia) 鐵離子（Fe²⁺）氧化為(wei) 三價(jia) 鐵離子（Fe³⁺），同時產(chan) 生硫酸；然後，Fe³⁺進一步將 FeS₂氧化，自身又被還原為(wei) Fe²⁺，如此循環往複，實現黃鐵礦的持續氧化分解，從(cong) 而將硫從(cong) 煤炭中分離出來。在廢氣生物脫硫方麵，微生物則主要將廢氣中的硫化氫（H₂S）等含硫氣體(ti) 轉化為(wei) 單質硫或硫酸鹽，達到淨化廢氣的目的。

Biological desulfurization technology is mainly based on the metabolic activity of microorganisms to achieve sulfur removal. In nature, there are some special microorganisms such as Thiobacillus ferrooxidans and Thiobacillus thiooxidans, which have unique metabolic pathways and can use sulfur-containing compounds as energy substances for growth and reproduction. Taking coal biological desulfurization as an example, these microorganisms can oxidize pyrite (FeS ₂) in coal to ferrous sulfate (FeSO ₄) and sulfuric acid (H ₂ SO ₄). The reaction process is as follows: firstly, microorganisms oxidize divalent iron ions (Fe ² ⁺) in FeS ₂ to trivalent iron ions (Fe ³ ⁺), while producing sulfuric acid; Then, Fe ³ ⁺ further oxidizes FeS ₂ and is reduced to Fe ² ⁺, repeating this process to achieve continuous oxidation and decomposition of pyrite, thereby separating sulfur from coal. In terms of biological desulfurization of exhaust gas, microorganisms mainly convert sulfur-containing gases such as hydrogen sulfide (H ₂ S) in exhaust gas into elemental sulfur or sulfate, achieving the purpose of purifying exhaust gas.

顯著優(you) 勢盡顯​

Significant advantages are fully demonstrated

生物脫硫技術具有顯著的環保優(you) 勢。相較於(yu) 傳(chuan) 統化學脫硫方法，它無需使用大量的化學試劑，避免了因化學試劑的使用和排放而造成的二次汙染。同時，生物脫硫過程產(chan) 生的廢棄物主要是微生物菌體(ti) 和少量的硫酸鹽，這些廢棄物易於(yu) 處理，對環境的影響極小。例如，在一些工業(ye) 廢氣生物脫硫項目中，廢氣中的二氧化硫（SO₂）被微生物轉化為(wei) 單質硫，可作為(wei) 化工原料回收利用，實現了資源的循環利用。​

Biological desulfurization technology has significant environmental advantages. Compared to traditional chemical desulfurization methods, it does not require a large amount of chemical reagents, avoiding secondary pollution caused by the use and discharge of chemical reagents. Meanwhile, the waste generated during the biological desulfurization process mainly consists of microbial cells and a small amount of sulfate, which are easy to handle and have minimal impact on the environment. For example, in some industrial waste gas biological desulfurization projects, sulfur dioxide (SO ₂) in the waste gas is converted into elemental sulfur by microorganisms, which can be recycled as chemical raw materials and achieve resource recycling. ​

從(cong) 經濟成本角度來看，生物脫硫技術也具有明顯優(you) 勢。由於(yu) 其無需複雜的設備和大量的化學藥劑，設備投資和運行成本相對較低。而且，微生物的培養(yang) 和生長所需的營養(yang) 物質來源廣泛且價(jia) 格低廉，進一步降低了脫硫成本。據相關(guan) 研究表明，生物脫硫的成本相較於(yu) 傳(chuan) 統化學脫硫可降低 30% - 50%，為(wei) 企業(ye) 減輕了經濟負擔。​

From an economic cost perspective, biological desulfurization technology also has significant advantages. Due to its lack of complex equipment and large amounts of chemical agents, equipment investment and operating costs are relatively low. Moreover, the cultivation and growth of microorganisms require a wide range of nutrients at low prices, further reducing the cost of desulfurization. According to relevant research, the cost of biological desulfurization can be reduced by 30% to 50% compared to traditional chemical desulfurization, which reduces the economic burden on enterprises. ​
