Abstract：

In　order　to　solve　the　problem　of　shortage　of　carbon　source,　the　poor　biological　denitrification,　and　large　production　of　waste　activated　sludge　(WAS)　in　the　urban　sewage　treatment　plants,　the　effects　of　alkaline　fermented　liquid　as　external　carbon　source　on　biological　denitrification　and　phosphorus　removal　efficiency　were　studied　with　the　method　of　adding　different　ratio　of　alkaline　fermented　liquid　into　A2O　system.　The　results　showed　that　with　the　amount　of　alkaline　fermented　liquid　additive　increasing,　the　inflow　pH　value　of　A2O　system　increased,　and　the　COD　and　NH4+-N　removal　efficiency　basically　remain　unchanged,　but　the　TN　and　PO43--P　removal　efficiency　slightly　decreased.　When　all　the　external　carbon　source　were　provided　by　fermented　liquid,　COD,　NH4+-N,　TN　and　PO43--P　removal　rate　were　87.00%,　98.86%,　79.93%　and　80.92%　respectively,　and　NH4+-N,　TN　and　PO43--P　remove　quantity　were　improved　by　24.93%,　19.05%　and　86.08%　respectively　than　single　additive　sodium　acetate.　©,　2015,　Beijing　University　of　Technology.　All　right　reserved.
