　　生物脫硫的運行成本通常低于每立方米沼氣0.02元（即2分錢），具體成本受處理規(guī)模、技術成熟度等因素影響。以下是關鍵信息整合：

　　The operating cost of biological desulfurization is usually lower than 0.02 yuan per cubic meter of biogas (i.e. 2 cents), and the specific cost is affected by factors such as treatment scale and technological maturity. The following is the key information integration:

　　成本范圍

　　Cost range

　　多數(shù)案例顯示，生物脫硫的綜合運行成本低于每立方米沼氣0.02元，部分項目甚至可低至0.01元/立方米。這一成本顯著低于傳統(tǒng)脫硫方法（如干式脫硫、堿洗脫硫等）。

　　Most cases show that the comprehensive operating cost of biological desulfurization is less than 0.02 yuan per cubic meter of biogas, and some projects can even be as low as 0.01 yuan per cubic meter. This cost is significantly lower than traditional desulfurization methods such as dry desulfurization, alkali washing desulfurization, etc.

　　成本優(yōu)勢

　　cost advantage

　　長期經(jīng)濟性 ：運行費用較傳統(tǒng)脫硫方式低30%以上，投資回收期通常為5-8年。

　　Long term economy: Operating costs are more than 30% lower than traditional desulfurization methods, and the investment payback period is usually 5-8 years.

　　環(huán)保效益 ：硫去除率可達90%以上，符合可持續(xù)發(fā)展需求。

　　Environmental benefits: The sulfur removal rate can reach over 90%, which meets the requirements of sustainable development.

　　技術特點

　　Technical Features

　　生物脫硫通過微生物（如硫桿菌屬、絲硫菌屬）在生物填料上代謝硫化氫實現(xiàn)脫硫，需配合營養(yǎng)液循環(huán)維持填料濕潤環(huán)境。其運行成本低、能耗低，且無需頻繁更換設備。

　　Biological desulfurization is achieved by microorganisms (such as sulfur bacteria and silk sulfur bacteria) metabolizing hydrogen sulfide on biological fillers, which requires the circulation of nutrient solution to maintain a moist environment of the fillers. It has low operating costs, low energy consumption, and does not require frequent equipment replacement.

　　應用案例

　　Application Cases

　　國家863計劃項目及寧波污泥綜合處理項目均采用生物脫硫技術，處理效率可達90%以上，且運行成本穩(wěn)定低于0.02元/立方米。

　　Both the National 863 Program project and the Ningbo Sludge Comprehensive Treatment Project adopt biological desulfurization technology, with a treatment efficiency of over 90% and a stable operating cost of less than 0.02 yuan/cubic meter.

　　總結 ：生物脫硫憑借低成本、高效率和環(huán)保性，已成為沼氣處理的首選技術之一，實際運行成本受項目規(guī)模和技術優(yōu)化程度影響，但普遍低于傳統(tǒng)脫硫方法。

　　Summary: Biological desulfurization has become one of the preferred technologies for biogas treatment due to its low cost, high efficiency, and environmental friendliness. The actual operating cost is affected by the project scale and the degree of technological optimization, but it is generally lower than traditional desulfurization methods.
