| 摘 要： | 配置不同浓度的葡萄糖溶液、NaNO2溶液及混合溶液,考察了NO2-对有机物测定结果的影响,并在已实现短程硝化的SBR反应器中研究了有机物在亚硝酸盐积累过程中的降解情况及其对短程硝化的影响.结果表明,测定含NO2-废水中有机物浓度时需要采用公式COD校核＝COD实测-NO2--N]COD计进行校核.在DO较低(0.8～...

| Abstract: | The effect of NO-2 on the measurement of organics were investigated by preparing glucose solution,sodium nitrite solution and glucose-nitrite mixed solution in different concentrations,and the degradation of organics and its effect on shortcut nitrification during nitrite accumulation were studied in the SBR which had achieved nitrification.The result showed that the organics concentration was verified in terms of the formula(modified COD=measured COD-NO-2-N](in COD)) as NO-2 existing in wastewater.The sys... |
