| 摘 要： | 研究不同有机负荷条件下,气升式间歇反应器(SBAR)中培养好氧颗粒污泥,并观察其形态变化及处理模拟生活污水的效果。实验结果表明,在SBAR中,有机负荷为3kgCOD/(m3.d)和6 kgCOD/(m3.d)下均可以培养出成熟的好氧颗粒污泥,SVI值分别为25mL/g和32mL/g,沉降速度分别达到33.85m/h和33m/h。但较高的有机负荷条件下,培养出的污泥颗粒的粒径大多数在0.6mm～1.5mm,且COD、氨氮和总磷的去除率分别可达97.57%、87.74%和86.60%;较低有机负荷条件下形成的污泥颗粒粒径多数在0.4mm～1.0mm之间,COD、氨氮和总磷的去除率分别为96.93%、85.48%和84.20%。 |

| Abstract: | Influence of different organic loadings on characteristics of aerobic granular sludge in sequencing batch airlift reaction(SBAR) was studied.Formation of aerobic granular sludge and effect of treating municipal wastewater were observed.Results showed that there exists aerobic granular sludge on different organic loadings of 3kgCOD/(m3·d) and 6kgCOD/(m3·d) in SBAR,with SVI of 25mL/g and 32mL/g respectively and settling velocity up to 33.85m/h and 33m/h.At higher organic loading,sludge diameter was in 0.6～1.5mm,and removal efficiency of COD,NH3-N and TP was 97.57%,87.74% and 86.60% respectively.With lower organic loading,sludge diameter was in 0.4～1.0mm,and removal efficiency of COD,NH3-N and TP was 96.93%,85.48% and 84.20% respectively. |
