生物脫硫技術相比化學脫硫具有以下幾個主要優勢：

Compared to chemical desulfurization, biological desulfurization technology has the following main advantages:

脫硫效率高：生物脫硫設備在運行中硫化氫（H2S）去除率最高可達99.5%以上，并且能夠去除其他有機硫化物，如氧硫化碳（COS）。

High desulfurization efficiency: Biological desulfurization equipment can achieve a maximum removal rate of over 99.5% for hydrogen sulfide (H2S) during operation, and can also remove other organic sulfides such as carbon oxysulfide (COS).

運行成本低：盡管生物脫硫設備的前期一次性投入較大，但其運行不需要添加昂貴的化學試劑，因此運行成本遠低于傳統脫硫工藝，大約是傳統脫硫工藝的十分之一乃至幾十分之一。

Low operating cost: Although the initial one-time investment of biological desulfurization equipment is relatively large, its operation does not require the addition of expensive chemical reagents, so the operating cost is much lower than traditional desulfurization processes, about one tenth or even one tenth of traditional desulfurization processes.

運行穩定：生物脫硫生產的單質硫水溶性非常好，不會堵塞管道，而傳統的干法脫硫工藝最大的問題是經常性堵塞。

Stable operation: The elemental sulfur produced by biological desulfurization has excellent water solubility and will not block pipelines, while the biggest problem with traditional dry desulfurization processes is frequent blockage.

無二次污染：傳統的濕法脫硫會產生大量的洗滌液廢水，傳統干法脫硫工藝會產生大量的固體廢棄物，都容易產生二次污染。相比之下，生物脫硫產生的單質硫通過沉淀的方式直接可回收利用，無二次污染。

No secondary pollution: Traditional wet desulfurization generates a large amount of washing solution wastewater, while traditional dry desulfurization processes generate a large amount of solid waste, both of which are prone to secondary pollution. In contrast, the elemental sulfur produced by biological desulfurization can be directly recycled and reused through precipitation, without secondary pollution.

勞動強度低：傳統干法脫硫工藝需要經常更換脫硫劑，勞動強度大，而生物脫硫工藝運行穩定，基本不需要設備維護。

Low labor intensity: Traditional dry desulfurization processes require frequent replacement of desulfurizers, resulting in high labor intensity, while biological desulfurization processes operate stably and require minimal equipment maintenance.

環境友好：生物脫硫技術無需使用大量化學試劑，減少了對環境的破壞，通過微生物作用將硫化氫轉化成硫單質，避免了化學試劑可能帶來的環境污染。

Environmentally friendly: Biological desulfurization technology does not require the use of large amounts of chemical reagents, reducing environmental damage. Through microbial action, hydrogen sulfide is converted into elemental sulfur, avoiding potential environmental pollution caused by chemical reagents.

適應性強：生物脫硫技術可以適應不同的工況條件，包括中低含硫量天然氣的處理，彌補了傳統化學脫硫技術的不足。

Strong adaptability: Biological desulfurization technology can adapt to different working conditions, including the treatment of low to medium sulfur natural gas, making up for the shortcomings of traditional chemical desulfurization technology.

綜上所述，生物脫硫技術在效率、成本、環境影響和操作便利性方面相比化學脫硫顯示出明顯的優勢。

In summary, biological desulfurization technology has shown significant advantages over chemical desulfurization in terms of efficiency, cost, environmental impact, and operational convenience.
