| 摘 要： | 在序批式生物反应器(SBR)中,分别在运行周期为6h、12h条件下调节进水浓度使得两反应器的容积负荷相等,比较两个反应器中好氧颗粒污泥的性状、氨氮去除情况及氮的形态转化。结果表明:在相等的容积负荷下,与运行周期为6h相比,运行周期为12h时的好氧颗粒粒径稍大,其他物理性状无明显不同。运行周期为12h时的氨氮平均去除率更...

| Abstract: | Two bench-scaled SBRs were operated with different cycles(6h and 12h respectively)and different influent concentrations of COD to retain a similar volume loading when conducting a comparative study of the aerobic granular sludge within them regarding removal rate of nitrogen and N speciation.It was found that particle size of the aerobic granular sludge was larger and the average ammonia nitrogen removal rate higher in the reactor with longer working cycle(12h)but the characteristics of sludge in both SBRs ... |
