摘　　要：以生物滤池为反应器,考察了厌氧氨氧化滤池的pH值与基质去除的变化规律。试验结果表明,pH值随滤层的加深而变化,在pH=7.58时,变化趋势较缓慢;pH(7.58时,pH值变化幅度较大,氨氮和亚硝酸盐氮的平均去除负荷较高,分别为0.97 kg/(m3.d)、1.06 kg/(m3.d);而pH(7.58时,pH值是先下降后上升,氨氮和亚硝酸盐氮的平均去除负荷较低,分别为0.56 kg/(m3.d)、0.73 kg/(m3.d)。在pH=7.98时去除负荷达到最大,去除负荷分别为1.42 kg/(m3.d)、1.84 kg/(m3.d)。Biofilter for the reactor,inspected the anaerobic ammonia oxidation and pH value of the filter substrate removal of the changes.The results show that pH value of the filter with the increasing gradually changing,at pH=7.58,trend of slower;pH〉7.58,with the pH value of the filter to increase its change to a little larger,ammonia and nitrite salt removal of the average nitrogen load higher,are 0.97 kg/（m3·d）、1.06 kg/（m3·d）,respectively;and pH〈7.58,the pH value is increased after the first drop,ammonia and nitrite removal of the average nitrogen load is lower,are 0.56 kg/（m3·d）、0.73 kg/（m3·d）.In the removal of maximum load when pH=7.98,load removal are 1.42 kg/（m3·d）、1.84 kg/（m3·d）.
