| 摘 要： | 在序批式活性污泥反应器(SBR)内,以模拟的城市污水为处理对象,研究DO、C/N等因素对同步硝化反硝化脱氮效率的影响。研究表明:采用连续曝气工艺,在进水COD=200mg/L,NH4+-N=30mg/L条件下,控制DO在0.5～1.5mg/L范围内时,出水TN浓度为1.98～6.3mg/L,TN的平均去除率在80%以上,最高去除率达到93.74%,并可推断出在反应系统内存在好氧反硝化菌;C/N在3.3～10之间时,C/N越高,出水NO3--N浓度越低,SND效果越好。

| Abstract: | This paper refers to an experiment treating municipal wastewater in a SBR lab installation, controlling aeration maintaining DO within the range of 0.5-1.5mg/L. COD and total nitrogen (TN) in influent maintain constant of 200mg/L and 30mg/L respectively. According to the experimental result showing more than 80% TN removal, the study suggests aerobic denitrification, i.e., simultaneous nitrification and denitrification (SND), took place during the operation. |
