To　investigate　the　feasibility　of　a　biological　method　for　elimination　of　odorous　gas　from　wastewater　treatment　plants,　a　biotrickling　filter　(BTF),　biofilter,　and　bioscrubber　were　used　to　treat　the　odorous　gas,　which　was　collected　from　four　tanks　(sanitary　sewage　lifting　tank,　oxidation　tank,　accident　tank,　and　adjusting　tank)　of　a　Sinopec　chemical　fiber　wastewater　treatment　plant.　The　results　show　that　when　the　treatment　capacity　increased　from　0.1　m3·h-1　to　0.2　m3·h-1,　the　corresponding　empty　bed　residence　time　(EBRT)　was　cut　from　172　s　to　86　s.　The　BTF＇s　removal　efficiencies　of　methyl　alcohol,　ethyl　alcohol,　cyclohexane,　and　m-xylene　increased　to　96.80%,　100.00%,　92.15%,　and　99.68%,　respectively.　Furthermore,　the　three　biological　reactors　showed　good　adaptability　to　air　temperature　changes,　but　the　BTF＇s　pressure　drop　remained　undetected.　Hence,　the　odorous　gas　from　this　chemical　fiber　wastewater　treatment　plant　was　efficiently　eliminated　by　BTF　technology.　©　2017,　Science　Press.　All　right　reserved.
