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.
