Abstract：

External　carbon　source　and　alkalinity　need　to　be　supplied　for　nitrogen　removal　from　digestion　liquid　with　high　concentrations　of　ammonia,　low　C/N　ratio　and　low　concentrations　of　alkalinity　by　traditional　nitrogen　removal　technologies.　In　this　investigation,　a　novel　system　consisted　of　an　A/O　reactor　and　SIFEDEN　(SImultaneous　FErmentation　and　DENitrification)　reactor　was　used　for　nitrogen　removal　from　digestion　liquid.　Firstly,　nitritation　of　digestion　liquid　was　finished　in　the　A/O　reactor.　Secondly,　nitrite　and　nitrate　in　effluent　of　the　A/O　reactor　were　removed　in　the　SIFEDEN　reactor　by　using　primary　sludge　hydrolyzed　and　fermented　as　carbon　sources.　Total　nitrogen　removal　efficiency　of　digestion　liquid　was　about　87%　and　volatile　suspended　solid　(VSS)　of　primary　sludge　was　decreased　by　about　49%.　The　reciprocal　relation　between　sludge　fermentation　and　digestion　liquid　denitrification　and　variation　of　pH　in　the　SIFEDEN　reactor　were　investigated.　When　effluent　of　the　system　was　reflowed　into　mainstream　of　wastewater　treatment　plant　after　accomplishing　highly　effective　siding　nitrogen　removal,　the　C/N　ratio　of　raw　municipal　wastewater　was　not　decreased　to　improve　nitrogen　removal　efficiency　of　municipal　wastewater.
