The dielectric barrier discharge plasma technology was applied to decompose the hydrogen sulfide so as to control malodor. The effects of voltage, frequency, initial concentration and retention time on removal efficiency of hydrogen sulfide were investigated. The results showed that hydrogen sulfide could be removed efficiently by the dielectric barrier discharge, and the removal efficiency increased with the rising of voltage, frequency and retentiontime, while the removal efficiency decreased with the rising of gas initial concentration. Under the operating condi-tions of voltage was≥19 kV, frequency was 300 Hz, retention time was 1.56 s and inlet concentration of hydrogensulfide was 30.1 mg/m~2 , the removal efficiency of hydrogen sulfide approximated to 100%.
