HIGH CONCENTRATION H2S ELIMINATION SYSTEM AND HIGH CONCENTRATION H2S ELIMINATION METHOD

Abstract

A high concentration H2S elimination system and a method using the same are disclosed. The system of the present invention comprises: a chemical H2S elimination module with a gas inlet, a gas outlet and a liquid outlet, wherein H2 S-containing gas is introduced into the chemical H2S elimination module; a reagent storage unit containing an oxidant; a liquid spray unit, wherein the oxidant contained in the reagent storage unit is introduced into the chemical H2S elimination module from the liquid inlet thereof through the liquid spray unit; a bio-regeneration unit comprising a microorganism to regenerate oxidant and connecting to the reagent storage unit; and a sulfur-removing module connecting to the liquid outlet of the chemical H2S elimination module.
