| 摘 要： | 接种0～4℃贮存2个月亚硝酸盐反硝化颗粒污泥，以甲醇为电子供体、亚硝酸盐为电子受体在USB(上流式污泥床)反应器内进行二次启动。结果显示，在逐步提高进水负荷下，约46 d完成了反应器二次启动，污泥床负荷达到3.43 g N/（L·d），NO2-N去除率为99%；在稳定运行阶段，当进水NO2-N浓度为50 mg/L、负荷从1.7 g N/（L·d）逐步提高至5.1 g N/（L·d）时，NO2-N去除率均大于98%；当表观流速为2.68 m/h、进水负荷逐步提高至8.0 g N/（L·d）时，脱氮率下降至63%，过程中污泥床最大去除速率约为5.7 g N/（L·d）。研究认为，亚硝酸盐颗粒污泥床具有稳定和去除效率高等特点。

| Abstract: | The secondary start-up,using methanol as electron donor and nitrite as electron accepter,was completed within 46 days in the USB reactor,which was inoculated nitrite denitrifying granular sludge that had been deposited under 0～4℃ for two months.The results showed that the loading rate of USB reactor was 3.43 nitrite removal rate was more than 98%.When the superficial water velocity was 2.68 m/h.the loading rate of sessed of stabilization and high removal efficiencies. |
