Is it feasible to treat wastewater containing hydrogen sulfide using steam stripping?
Thread Content
The wastewater contains hydrogen sulfide and ammonia, which exist in the form of NH3HS; the sulfur content is 30% by mass. I would like to ask the experts whether it is feasible to use steam stripping for treatment, and what is the efficiency of this method in removing sulfur? How much sulfur is contained in the wastewater after air lifting? This post was last edited by qingshan8269 on 2008-1-7 14:27.]
It is basically not feasible; the stripping method can reduce it to 30–50 ppm, and it becomes even more difficult beyond that.
I’m sorry, I made a mistake; the sulfur content is 30%, and I’ve corrected it now. Thank you, 2nd floor
That should work then; the stripping method can reduce the concentration to 30–50 ppm, which is more than sufficient for the next processing step. The volume of work is not very large, and auditors of varying levels can generally handle the design requirements. If the requirements are not strict, one can build it themselves; it is recommended to use a large design institute to ensure safety and environmental protection.
Steam water stripping can meet the process requirements; ammonia is also dissolved in water, and it is estimated that the emissions after steam water stripping will meet the specified standards
Steam stripping treatment is feasible
