目前污水、垃圾處理過程中，越來越多的工程項目選用厭氧處理工藝，沼氣作為一種衍生產物，漸漸被我們所熟知并利用。但從厭氧罐中出來的沼氣含有較高濃度的H2S及其它一些雜質，如不對沼氣進行脫硫、凈化處理，則會對沼氣運送管道、存儲設備及后續運用設備發生腐蝕，削減運用年限并形成安全危險。所以，通常是先通過脫硫凈化處理后再利用。
At present, in the process of sewage and garbage treatment, more and more projects choose anaerobic treatment technology. As a derivative, biogas is gradually known and used by us. But the biogas from the anaerobic tank contains high concentration of H2S and other impurities. If the biogas is not desulfurized and purified, it will corrode the biogas transportation pipeline, storage equipment and follow-up equipment, reduce the service life and form a safety hazard. Therefore, it is usually first treated by desulphurization and then reused.
常用的沼氣生物脫硫體系一般通過風機供氧的方法，添加沼氣中的氧氣含量，并通過微生物的效果，將H2S轉化為硫單質。沼氣脫硫體系的H2S通過處理后，會生成硫單質，因為處理后發生的硫單質量十分少，很難進行再生利用，并且硫單質在氣溫高時，會有提高現場，屬于風險廢 物，現場堆置或運送都存在安全危險；另外，沼氣生物脫硫體系的操控設備的智能化程度低，大部分由人進行現場操作，對人身安全帶來很大的危險。
The commonly used biogas biological desulfurization system is usually supplied by air blower, adding oxygen content in biogas, and converting H2S into sulfur by microbial effect. The H2S of biogas desulfurization system will produce sulfur element after treatment, because the quality of sulfur element after treatment is very small, it is difficult to recycle, and sulfur element will improve the site when the temperature is high, which belongs to risk waste, and there are safety risks in site stacking or transportation; in addition, the operation of biogas desulfurization system. The intelligent degree of control equipment is low, and most of them are operated by people on site, which brings great danger to personal safety.
