在工業生產中，脫硫是一道繞不開的關鍵工序，傳統脫硫技術長期占據主導地位。然而，隨著環保要求日益嚴苛和對成本控制的極致追求，生物脫硫技術異軍突起，其在運營成本方面與傳統技術相比，究竟能帶來多大驚喜？這成為眾多企業關注的焦點。

　　In industrial production, desulfurization is a crucial process that cannot be bypassed, and traditional desulfurization technology has long dominated. However, with increasingly stringent environmental requirements and the ultimate pursuit of cost control, biological desulfurization technology has emerged as a new force. Compared with traditional technologies, how much surprise can it bring in terms of operating costs? This has become the focus of attention for many enterprises.

　　傳統脫硫技術，如濕法脫硫、干法脫硫，雖技術成熟，但運營成本猶如一座沉重的大山。以濕法脫硫為例，需要消耗大量的化學試劑，像石灰石 - 石膏法，需持續投入石灰石粉用于與二氧化硫反應，且后續處理生成的石膏也需不菲費用。據行業數據，濕法脫硫每處理 1 立方米含硫氣體，化學試劑成本可達 0.2 - 0.5 元。同時，該工藝設備龐大復雜，運行時能耗極高，大型濕法脫硫裝置的電力消耗每月可達數萬度，折算下來，每立方米氣體的能耗成本在 0.1 - 0.3 元左右。設備維護也不容小覷，頻繁接觸腐蝕性氣體和液體，設備易損壞，維修、更換零部件成本高昂，每年維護費用占總運營成本的 15% - 20%。

　　Traditional desulfurization technologies, such as wet desulfurization and dry desulfurization, although mature, have operating costs like a heavy mountain. Taking wet desulfurization as an example, it requires a large amount of chemical reagents, such as the limestone gypsum method, which requires continuous input of limestone powder for reaction with sulfur dioxide, and the subsequent treatment of the resulting gypsum also requires significant costs. According to industry data, the cost of chemical reagents for wet desulfurization can reach 0.2-0.5 yuan per cubic meter of sulfur-containing gas processed. At the same time, the process equipment is large and complex, with extremely high energy consumption during operation. The electricity consumption of large-scale wet desulfurization units can reach tens of thousands of kilowatt hours per month. Converted, the energy consumption cost per cubic meter of gas is around 0.1-0.3 yuan. Equipment maintenance should not be underestimated. Frequent exposure to corrosive gases and liquids can easily damage the equipment, and the cost of repairing and replacing parts is high. The annual maintenance cost accounts for 15% -20% of the total operating cost.

　　反觀生物脫硫技術，宛如一位精打細算的 “成本管家”，在各個環節展現出顯著的成本優勢。從化學試劑角度看，生物脫硫主要依靠微生物的代謝作用來轉化硫化物，僅需補充少量用于維持微生物生長的營養液，如氮、磷等營養鹽，無需大量昂貴的化學藥劑。這使得化學試劑成本大幅降低，每處理 1 立方米含硫氣體，試劑成本可低至 0.01 - 0.03 元，相比傳統濕法脫硫，降幅高達 80% 以上。

　　On the other hand, biological desulfurization technology is like a meticulous cost manager, demonstrating significant cost advantages in every aspect. From the perspective of chemical reagents, biological desulfurization mainly relies on the metabolic action of microorganisms to convert sulfides, requiring only a small amount of nutrient solution to maintain microbial growth, such as nitrogen, phosphorus and other nutrients, without the need for large amounts of expensive chemical agents. This significantly reduces the cost of chemical reagents. For every cubic meter of sulfur-containing gas processed, the cost of reagents can be as low as 0.01-0.03 yuan, which is more than 80% lower than traditional wet desulfurization.

　　能耗方面，生物脫硫更是表現出色。微生物在適宜環境下即可高效工作，無需高溫、高壓等極端條件，其能耗主要集中在為微生物提供適宜生存環境的輔助設備上，如維持反應溫度的控溫裝置、保證微生物有氧呼吸的供氣設備等。整體算下來，生物脫硫每立方米氣體的能耗成本在 0.02 - 0.05 元，相較于傳統濕法脫硫能耗成本降低約 60% - 80%，與干法脫硫相比，能耗優勢也十分明顯。

　　In terms of energy consumption, biological desulfurization performs even better. Microorganisms can work efficiently in suitable environments without extreme conditions such as high temperature and high pressure. Their energy consumption is mainly concentrated in auxiliary equipment that provides a suitable living environment for microorganisms, such as temperature control devices to maintain reaction temperature and gas supply equipment to ensure aerobic respiration of microorganisms. Overall, the energy consumption cost of biological desulfurization per cubic meter of gas is 0.02-0.05 yuan, which is about 60% -80% lower than that of traditional wet desulfurization. Compared with dry desulfurization, the energy consumption advantage is also very obvious.

　　在設備維護與使用壽命上，生物脫硫技術同樣具有優勢。其設備結構相對簡單，沒有復雜的高溫、高壓部件，也不存在因化學腐蝕導致的頻繁損壞問題。微生物反應環境相對溫和，對設備材質要求不像傳統技術那般苛刻，設備使用壽命得以延長。據實際案例，生物脫硫設備的維修周期可比傳統脫硫設備延長 2 - 3 倍，每年維護成本可控制在總運營成本的 5% - 10%，大大減少了設備維修和更換的支出。

　　Biological desulfurization technology also has advantages in equipment maintenance and service life. Its equipment structure is relatively simple, without complex high-temperature and high-pressure components, and there is no frequent damage caused by chemical corrosion. The microbial reaction environment is relatively mild, and the requirements for equipment materials are not as strict as traditional technologies, which extends the service life of equipment. According to actual cases, the maintenance cycle of biological desulfurization equipment can be extended by 2-3 times compared to traditional desulfurization equipment, and the annual maintenance cost can be controlled at 5% -10% of the total operating cost, greatly reducing equipment maintenance and replacement expenses.

　　綜合來看，生物脫硫技術的運營成本較傳統脫硫技術大幅降低。在一些實際項目中，生物脫硫的運行成本僅為傳統濕法脫硫的三分之一，甚至低至十分之一。以某大型化工企業為例，采用生物脫硫技術后，每年在脫硫環節的運營成本節省了數百萬元。生物脫硫技術憑借其卓越的成本控制能力，為企業在滿足環保要求的同時，降低了生產成本，提升了市場競爭力，成為脫硫領域一顆冉冉升起的新星，正逐步改寫傳統脫硫技術主導的格局 。

　　Overall, the operating costs of biological desulfurization technology are significantly reduced compared to traditional desulfurization technology. In some practical projects, the operating cost of biological desulfurization is only one-third of that of traditional wet desulfurization, and even as low as one tenth. Taking a large chemical enterprise as an example, adopting biological desulfurization technology has saved millions of yuan in annual operating costs in the desulfurization process. Biological desulfurization technology, with its excellent cost control capabilities, has reduced production costs and enhanced market competitiveness for enterprises while meeting environmental requirements. It has become a rising star in the desulfurization field and is gradually rewriting the traditional desulfurization technology dominated pattern.
