Abstract
Gas-phase O3 oxidation is effective to treat H2S emitted from wastewater treatment processes. The reaction is fast for full-scale applications. In most cases, 67–96% of total H2S removed in 40-s reaction time was achieved within the first 8 s of reaction time. The initial [O3]/[H2S] ratio of 8 was sufficient to reduce H2S from up to 8 ppmv to less than 0.5 ppmv in 40-s reaction time. The reaction stoichiometry ratio of [O3]/[H2S] ranged from 2.0 to 3.7, depending on the initial [O3]/[H2S] ratio. The moisture content, dimethyl sulfide, and dimethyl disulfide in the odorous air influence H2S removal.Keywords
