摘　　要：研究了在低基质质量浓度条件下ANAMMOX生物滤池的脱氮效果.试验结果显示,NH_4^+-N的质量浓度在10～25 mg/L时,厌氧氨氧化滤池具有很高的基质去除率,NH_4^+-N的平均去除率为93.07%,NO_2^--N的平均去除率为82.23%,NO_2^--N与NH_4^+-N适宜的配比值为1.34,生物滤池脱氮高效段的滤池深度为0～60 cm.Anaerobic ammonium oxidation(ANAMMOX)is a novel technique with low consumption and high nitrogen removal.This paper studied on the nitrogen removal efficiency of ANAMMOX biofilter at low substration concentration,and its result showed that ANAMMOX biofilter still had very high activity at low ammonium concentration range of 10 to 25 mg/L,the average ammonium removal rate is 93.07%and the nitrite removal rate is 82.23%.The proper ratio of ammonium and nitrite is 1.34,and the height of the biofilter where sub...
