Abstract：

Based　on　the　good　performance　of　COD　and　nutrients,　the　estrogens　(E1,　E2　and　EE2)　were　detected　to　investigate　the　estrogens　removal　capability　of　the　A2O　process.　The　removal　efficiency　of　E1,　E2　and　EE2　reached　92.7%,　100%　and　62.7%,　respectively.　In　further,　the　estrogen　mass　balance　analysis　revealed　that　estrogens　were　mainly　removed　in　the　anaerobic　zone　and　the　aerobic　zone,　which　indicated　that　the　adsorption　and　degradation　were　the　main　mechanisms.　The　roles　of　adsorption　and　degradation　in　estrogen　removal　were　studied　by　aerobic　batch　test　taking　the　inactivated　sludge　as　the　controlled　group.　The　results　showed　that　EE2　was　mainly　removed　by　the　activated　sludge　adsorption,　while　E1　and　E2　were　mainly　removed　through　biodegradation.
