　　沼氣生物脫硫效率如何計算？

　　How to calculate the efficiency of biogas biological desulfurization?

　　沼氣生物脫硫效率的計算方法可歸納如下：

　　The calculation method for the efficiency of biogas biological desulfurization can be summarized as follows:

　　一、計算公式

　　1、 Calculation formula

　　脫硫效率 = [（入口SO?濃度 - 出口SO?濃度） / （入口SO?濃度 × 100%）]

　　Desulfurization efficiency=[(inlet SO concentration - outlet SO concentration)/(inlet SO concentration x 100%)]

　　其中，入口和出口的二氧化硫濃度需折算至相同氧含量（通常為6%氧量）。

　　Among them, the sulfur dioxide concentration at the inlet and outlet needs to be converted to the same oxygen content (usually 6% oxygen content).

　　二、關(guān)鍵影響因素

　　2、 Key influencing factors

　　氧含量 ：需根據(jù)硫化氫含量動態(tài)調(diào)節(jié)供氧量（2~8%體積比），過高或過低均影響效率。

　　Oxygen content: The oxygen supply should be dynamically adjusted according to the hydrogen sulfide content (2-8% volume ratio), as too high or too low can affect efficiency.

　　pH值 ：維持pH約6，確保微生物活性。

　　PH value: Maintain a pH of about 6 to ensure microbial activity.

　　營養(yǎng)條件 ：使用過濾后的沼液提供營養(yǎng)，無需額外化學藥品。

　　Nutritional conditions: Use filtered biogas slurry to provide nutrients without the need for additional chemicals.

　　溫度 ：需控制在適宜范圍（通常20~30℃），過高可能微生物。

　　Temperature: It needs to be controlled within an appropriate range (usually 20-30 ℃), as excessive temperature may inhibit microorganisms.

　　三、效率范圍

　　3、 Efficiency Range

　　實際脫硫效率可達95%以上，遠高于傳統(tǒng)化學脫硫法（約20%）。

　　The actual desulfurization efficiency can reach over 95%, far higher than traditional chemical desulfurization methods (about 20%).
