The Taking Place and Removing of Hydrogen Sulfide in the Anaerobic Environment

AbstrcatHydrogen sulfide is a kind of harmful gas,which is mainly produced by sulfate-reducing bacteria (SRB) under the anaerobic environment.Accumulating in a large amount of hydrogen sulfide can not only cause the corrosion of steel and other metallic materials, but also make people and various kinds of living beings (especially aquatic living beings) to be poisonous.The physical-chemical property and the harm of hydrogen sulfide are presented.Its producing mechanism in anaerobic environment and corresponding qualitative and quantitative detective techniques and methods are defined.Some removing measurements in chemical,biological,physical aspects of hydrogen sulfide are discussed.
