摘　　要：目的研究ANAMMOX工艺在生物滤池中的脱氮性能，以提高该工艺在实际运行中的脱氮效率．方法采用ANAMMOX生物滤池作为反应器，控制反应水温在25～31℃，逐步增加进水NH；-N和N02--N的基质质量浓度，研究ANAMMOX生物滤池工艺在不同质量浓度负荷下各滤层脱氮规律．结果ANAMMOX生物滤池生物量分布呈现先增后减再逐渐趋于平缓的趋势．厌氧氨氧化生物量集中分布在0～50cm滤层，进水口处生物量较低．进水NH4^＋-N和N02^- -N的基质质量浓度分别在90mg／L、120mg／L时去除效率最佳．当进水NH4-N和N02-N的基质质量浓度分别高于120mg／L、160mg／L时，ANAMMOX脱氮性能受到较大的抑制作用．结论进水Ni4^＋-N和NO2^- -N的基质质量浓度对ANAMMOX脱氮性能有较大影响．Studying the performance of ANAMMOX denitrification process in biofilter was in order to improve the efficiency of denitrification process in actual operation. The test used ANAMMOX bio-filter as the reactor, controlled the temperature of reaction water during 25 - 31℃ and in- creased the influent concentration of NH4 - N and NO2 - N gradually to study the rule of denitri- fication of ANAMMOX biological filter layers in different concentrations load variation. The bio- mass distribution of ANAMMOX bio-filter was increased first then decreased and finallv stabi-lized. Anammox biomass concentrated in 0 - 50 cm filter layer and the biomass in water inlet is lower. When the influent concentration of NH4^＋- N and NO2^- - N were respectively 90 mg/L and 120 mg/L,the rate of removal is the highest, when the influent concentration of NH4^＋ -N and NO2^- -N were respectively higher than 120 mg/L, 160 mg/L,the denitrification performance of ANAMMOX is greatly inhibited. The Influent concentration of NH4^＋ - N and NO2^- - N have a grea- ter impact on the denitrification performance of ANAMMOX.
