摘要：

The　energy　consumption　analysis　for　the　removal　of　ammonia　and　phosphorous　is　studied　in　a　pilot-scale　sequencing　batch　reactor　(SBR)　of　8.8　m3.　Frequency　converter　is　used　to　control　ρ(DO)　at　the　constant　level　to　investigate　the　power　consumption　at　aerobic　stage　and　the　amount　of　the　additional　carbon　sources　in　different　ρ(DO),　temperatures　and　running　ways.　Results　show　that　frequency　converter　can　reduce　the　energy　consumption　of　about　49.4%　compared　with　the　full　load　operation,　when　ρ(DO)　is　set　to　2.0　mg·L-1.　The　electricity　consumption　is　negatively　correlated　with　the　temperature.　Finally,　the　operation　pattern　of　step-feeding　can　not　only　save　the　carbon　source　cost　of　47.6%,　but　also　reduce　the　energy　consumption　of　17.9%.
