| 摘 要： | 以厌氧氨氧化活性污泥作为接种物,以无机盐培养液作为实验用水,考察了溶解氧、进水NO2--N与NH4＋-N的比值对厌氧氨氧化反应的影响。反应体系中硝酸盐的产生量随溶解氧浓度增加而增大,总氮去除率则随溶解氧浓度的增加而降低,除氧实验时出水NO3--N浓度平均为67.2mg/L,总氮去除率平均为73.9%;不除氧时出水NO3--N浓度平均为83.0mg/L,总氮去除率平均为67.8%;当进水NO2--N与NH4＋-N比值为1.16时,利于厌氧氨氧化反应的进行,总氮去除率为62.78%。

| Abstract: | By using aerobic activated sludge as inoculum and with synthetic medium containing ammonium and nitrite,factors that could affect the reaction of Anammox,such as dissolved oxygen and ratio of NO2--N to NH4＋-N of influent,were studied in this paper.When dissolved oxygen was increased,the effluent concentration of NO3--N increased obviously and the removal rate of TN decreased correspondingly.Before the removal of dissolved oxygen,the average effluent concentration of NO3-N was 67.2 mg/L and the average removal rate of TN was 67.8%.After the removal of dissolved oxygen,the average effluent concentration of NO3-N was 83.0 mg/L and the average removal rate of TN was 73.9%;When the ratio of NO2--N to NH4＋-N of influent remained about 1.16,the average removal rate of TN was 62.78%. |
