摘　　要：厌氧氨氧化菌的2种不同接种污泥培养实验表明,厌氧消化污泥和好氧硝化污泥均可成功启动厌氧氨氧化过程。接种厌氧消化污泥比好氧硝化污泥培养的厌氧氨氧化菌启动快,但后者去除效果较好。接种好氧硝化污泥的反应器的厌氧氨氧化速率随着氨氮基质进水浓度的增加呈线性增加。进水氨氮浓度为280 mg/L时的氨氮平均去除率达91%;而接种厌氧消化污泥的相应氨氮平均去除率仅为52%。厌氧氨氧化过程以接种好氧硝化污泥来启动为宜。The culture of anaerobic ammonia oxidation biomass seeded with anaerobic digestion sludge and aerobic nitrification sludge were carried out in two sets of SBR reactor. The results illustrated that the two kinds of sludge set up the anammox process successfully. Anammox process seeded by digestion sludge set up more rapidly than that for the aerobic nitrification sludge. But NH4^＋ -N removal efficiencies for aerobic nitrification sludge are better than those for the anaerobic digest sludge. The experimental results show that the anammox reaction rate in- creased with increase of NH4^＋ -N concentration. The average NH4^＋ -N removal efficiency for influent of 280 mg NH4^＋ -N/L was 91% ; the corresponding average NH4^＋ -NN removal efficiency for digest sludge was only 52%. So the anammox process should be set up with aerobic nitrification sludge.
