沼氣生物脫硫是20世紀(jì)90年代發(fā)展起來的新技術(shù)，是在常溫常壓下利用利用微生物實(shí)現(xiàn)硫的價態(tài)轉(zhuǎn)換的一種新技術(shù)。生物脫硫工藝過程是將一定量的空氣導(dǎo)入含有硫化氫的沼氣中，在反應(yīng)器內(nèi)裝有大量的生物填料，它們?yōu)榧?xì)菌繁殖提供充分的空間。營養(yǎng)液的循環(huán)使填料保持潮濕狀態(tài)，并補(bǔ)充細(xì)菌生長繁殖所需營養(yǎng)。專屬絲硫菌屬、硫桿菌屬在新陳代謝的過程中吸收硫化氫，并將他們轉(zhuǎn)化為單質(zhì)硫，進(jìn)而轉(zhuǎn)化為硫酸。
Biological desulfurization of biogas is a new technology developed in the 1990s. It is a new technology that uses microorganisms to realize the valence conversion of sulfur at room temperature and pressure. Biological desulfurization process is to introduce a certain amount of air into biogas containing hydrogen sulfide. There are a large number of biological fillers in the reactor, which provide sufficient space for bacterial reproduction. The circulation of nutrient solution keeps the filler moist and supplements the nutrients needed for bacterial growth and reproduction. The exclusive Thiobacillus and Thiobacillus absorb hydrogen sulfide in the process of metabolism, and convert them into elemental sulfur, and then into sulfuric acid.
