The production of hydrogen sulfide occurs mainly during the anaerobic stage (including partial anaerobia), where sulfides are reduced anaerobically to elemental sulfur and hydrogen sulfide; generally, water quality turns black due to the presence of FeS.
The production of hydrogen sulfide mainly occurs during the anaerobic stage
Our wastewater is alkaline, and no sulfur-containing chemicals such as sulfuric acid are used in the treatment process; can hydrogen sulfide still be generated under such conditions?
Hydrogen sulfide is produced in anaerobic reactions, as sulfur is an essential element for methanogens; therefore, a sufficient concentration of sulfides is necessary to ensure the effectiveness of these anaerobic reactions； Hydrogen sulfide is produced by sulfate-reducing bacteria.
Are there any relevant technical documents? Send it to me so I can learn* it.
I no longer have the technical documents, but I have a set of materials that I collected back when I was learning * a long time ago; I’ve forgotten where I got them.
Today someone asked, to learn * a bit.
To some extent or another, sulfate ions are present even in clean surface water
