摘要 为了研究以海绵作填料利用半硝化(PN)—厌氧氨氧化(ANAMMOX)联合工艺对实际废水进行脱氮处理的可行性,在一上流式厌氧固定床反应器中,利用熊本东部的某污水处理厂的污泥脱滤液进行了试验研究。运行结果表明,联合工艺运行时,控制亚硝化反应器温度为(30±1)℃、pH为7.5、溶解氧为1 mg/L时,亚硝化的活性比较稳定,出水NO-2—N/NH3—N为1左右。对于ANAMMOX反应阶段,在较高的总氮负荷3.6 kgN/(m3.d)下,TN、NH3—N和NO-2—N的去除率分别达到70%、72%和91%,反应器处理效果较好。此外ANAMMOX反应器在(17±2)℃时NO-2—N去除率低于(25±1)℃时6%;但当环境温度升高时,ANAMMOX菌的活性可以迅速地从低温操作条件下恢复(2~3 d)。
