在工業(yè)生產(chǎn)中，脫硫是一道繞不開的關(guān)鍵工序，傳統(tǒng)脫硫技術(shù)長(zhǎng)期占據(jù)主導(dǎo)地位。然而，隨著環(huán)保要求日益嚴(yán)苛和對(duì)成本控制的極致追求，生物脫硫技術(shù)異軍突起，其在運(yùn)營(yíng)成本方面與傳統(tǒng)技術(shù)相比，究竟能帶來多大驚喜？這成為眾多企業(yè)關(guān)注的焦點(diǎn)。

　　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(tǒng)脫硫技術(shù)，如濕法脫硫、干法脫硫，雖技術(shù)成熟，但運(yùn)營(yíng)成本猶如一座沉重的大山。以濕法脫硫?yàn)槔枰拇罅康幕瘜W(xué)試劑，像石灰石 - 石膏法，需持續(xù)投入石灰石粉用于與二氧化硫反應(yīng)，且后續(xù)處理生成的石膏也需不菲費(fèi)用。據(jù)行業(yè)數(shù)據(jù)，濕法脫硫每處理 1 立方米含硫氣體，化學(xué)試劑成本可達(dá) 0.2 - 0.5 元。同時(shí)，該工藝設(shè)備龐大復(fù)雜，運(yùn)行時(shí)能耗極高，大型濕法脫硫裝置的電力消耗每月可達(dá)數(shù)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(shè)備維護(hù)也不容小覷，頻繁接觸腐蝕性氣體和液體，設(shè)備易損壞，維修、更換零部件成本高昂，每年維護(hù)費(fèi)用占總運(yùn)營(yíng)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(shù)，宛如一位精打細(xì)算的 “成本管家”，在各個(gè)環(huán)節(jié)展現(xiàn)出顯著的成本優(yōu)勢(shì)。從化學(xué)試劑角度看，生物脫硫主要依靠微生物的代謝作用來轉(zhuǎn)化硫化物，僅需補(bǔ)充少量用于維持微生物生長(zhǎng)的營(yíng)養(yǎng)液，如氮、磷等營(yíng)養(yǎng)鹽，無需大量昂貴的化學(xué)藥劑。這使得化學(xué)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(tǒng)濕法脫硫，降幅高達(dá) 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(xiàn)出色。微生物在適宜環(huán)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(huán)境的輔助設(shè)備上，如維持反應(yīng)溫度的控溫裝置、保證微生物有氧呼吸的供氣設(shè)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(tǒng)濕法脫硫能耗成本降低約 60% - 80%，與干法脫硫相比，能耗優(yōu)勢(shì)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(shè)備維護(hù)與使用壽命上，生物脫硫技術(shù)同樣具有優(yōu)勢(shì)。其設(shè)備結(jié)構(gòu)相對(duì)簡(jiǎn)單，沒有復(fù)雜的高溫、高壓部件，也不存在因化學(xué)腐蝕導(dǎo)致的頻繁損壞問題。微生物反應(yīng)環(huán)境相對(duì)溫和，對(duì)設(shè)備材質(zhì)要求不像傳統(tǒng)技術(shù)那般苛刻，設(shè)備使用壽命得以延長(zhǎng)。據(jù)實(shí)際案例，生物脫硫設(shè)備的維修周期可比傳統(tǒng)脫硫設(shè)備延長(zhǎng) 2 - 3 倍，每年維護(hù)成本可控制在總運(yùn)營(yíng)成本的 5% - 10%，大大減少了設(shè)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(shù)的運(yùn)營(yíng)成本較傳統(tǒng)脫硫技術(shù)大幅降低。在一些實(shí)際項(xiàng)目中，生物脫硫的運(yùn)行成本僅為傳統(tǒng)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(yè)為例，采用生物脫硫技術(shù)后，每年在脫硫環(huán)節(jié)的運(yùn)營(yíng)成本節(jié)省了數(shù)百萬元。生物脫硫技術(shù)憑借其卓越的成本控制能力，為企業(yè)在滿足環(huán)保要求的同時(shí)，降低了生產(chǎn)成本，提升了市場(chǎng)競(jìng)爭(zhēng)力，成為脫硫領(lǐng)域一顆冉冉升起的新星，正逐步改寫傳統(tǒng)脫硫技術(shù)主導(dǎo)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.
