How do you remove sulfide from wastewater?
Microbial oxidation for sulfide removal These treatment methods include: Air stripping: Sulfide is highly volatile, and at slightly acidic pH, it tends to partition out of the aqueous phase into the vapor phase, and, therefore, air stripping will remove sulfur from the aqueous phase.

What percent of h2s will kill you?
800 ppm is the lethal concentration for 50% of humans for 5 minutes’ exposure (LC50). Concentrations over 1000 ppm cause immediate collapse with loss of breathing, even after inhalation of a single breath.
Can you get sick from breathing in sewage?
