| 摘 要： | 为了确定短程内源反硝化的特性及其影响因素,采用SBR反应器,在20℃下,对以NO3-和NO2-为电子受体的内源反硝化脱氮状况进行了对比,并对不同污泥浓度下的短程内源反硝化速率进行了研究.结果表明,短程内源反硝化速率约为全程内源反硝化速率的1.6倍;污泥浓度从4g/L变化到12g/L时,短程内源反硝化速率平均值从0.026/d增加到0.038/d;短程内源反硝化间歇运行9个周期后,活性污泥的ρ(VSS)降低约16%,反硝化速率则降低了49%.

| Abstract: | To study the properties and effect factors of endogenous denitrification via nitrite, an SBR reactor was operated in denitrification at 20℃ using nitrogenous electron acceptor, i.e. NO3- and NO2- . Moreover, the endogenous partial denitrification rate was investigated at different mixed liquor suspended solids (MLSS). The results show that endogenous denitrification rate via nitrite was 1.6 times as much as that via nitrate. When the mixed liquor suspended solids changed from 4 g/L to 12 g/L, the endogenous denitrification rate increased from 0.026d-1 to 0.038 d-1. After 9 cyles of batch operation, a volatile suspended solids (VSS) reduction of 16% was achieved with a denitrification rate decrement of 49% . |
