In　order　to　explore　the　technological　characteristics　of　the　simultaneous　removal　of　phthalate　esters　(PAEs)　as　well　as　nitrogen　and　phosphorus　by　the　novel　technology　of　three-dimensional　biofilm-electrode　coupled　with　iron/sulfur　reactor　(3DBER-S-Fe),　the　changes　of　the　total　nitrogen　(TN),total　phosphorus　(TP),DBP,DEHP,NO3--N,　SO42-　and　pH　value　were　analyzed　under　the　hydraulic　retention　time　(HRT)　of　8　h,　6　h　and　4　h　respectively.　The　results　showed　that　3DBER-S-Fe　could　remove　nitrogen,　phosphorus　and　PAEs　effectively.　Under　the　HRT　of　8　h,　6　h　and　4　h,　the　removal　rates　of　TN　were　80.99%,　78.85%　and　64.76%;　TP　were　65.18%,　67.17%　and　43.44%;　DBP　were　96.72%,　97.32%　and　96.53%;　DEHP　were　91.89%,　81.57%　and　74.30%,　respectively.　There　were　heterotrophic　denitrification,　hydrogen　autotrophic　denitrification　and　sulfur　autotrophic　denitrification　processes　in　the　3DBER-S-Fe,　the　elemental　sulfur　could　compensate　for　the　relative　shortage　of　denitrification　electron　donor　caused　by　the　increase　of　NO3--N　load　in　the　influent　as　a　result　of　maintaining　a　high　efficiency　of　the　denitrification　system　when　the　HRT　was　shortened　from　8h　to　4h;　the　iron　ions　produced　by　the　corrosion　of　the　sponge　iron　filler　in　the　system　had　a　sustainable　and　efficient　function　of　removing　phosphorus　by　precipitation;　the　3DBER-S-Fe　process　combined　the　interactions　of　physical　adsorption,　biological　degradation　and　electrochemical　processes　which　supported　its　high　removal　rates　of　DBP　and　DEHP　under　the　different　HRT　conditions.　©　2016,　Science　Press.　All　right　reserved.
