An　experimental　research　on　hydrogen　sulfide　removal　by　DBD　was　carried　out.　This　study　explored　the　influences　of　initial　concentration,　gas　flow　rate,　applied　voltage　and　frequency　on　hydrogen　sulfide　removal.　In　addition,　the　differences　among　the　no　packing　and　ceramic　raschig-ring　packing　in　the　reactor　were　discussed.　Meanwhile,　during　plasma　processing　to　decompose　hydrogen　sulfide,　SIE　was　analyzed　using　the　Q-V　Lissajous　diagram.　The　experiment　data　suggested　that　hydrogen　sulfide　removal　efficiency　raised　with　the　addition　of　the　applied　voltage,　frequency　and　the　reducing　of　the　initial　concentration　of　hydrogen　sulfide　and　gas　flow;　it　was　found　that　under　the　following　conditions:　applied　voltage　19　W,　frequency　300　Hz,　gas　flow　rate　8　L/min,　inlet　gas　concentration　of　hydrogen　sulfide　30.1　mg/m(3),　the　hydrogen　sulfide　removal　reached　the　maximum　of　100%.　In　the　presence　of　the　packing,　hydrogen　sulfide　removal　efficiency　was　higher　than　in　the　case　of　no　packing,　93.26%　for　the　former　reactor　and　69.29%　for　the　latter.
