Geochemistry Characteristics Of Limestone Groundwater And Formation Mechanism Of H2s In Sanjiao

In order to observe the content of H2S in Sanjiao and its distribution characteristics, hydrogeology conditions of limestone aquifers were analyzed, and some water samples of Taiyuan formation and Shanxi formation were collected and tested, and geochemical characteristics of limestone groundwater were analyzed. Base on the above research, two mechanical models are provided, namely bacterial sulfate reduction and thermochemical sulfate reduction, which could explain genesis of H2S and its heterogeneous distribution.
