摘　　要：以3个经过高氨氮负荷冲击后的海洋厌氧氨氧化生物反应器为研究对象,其脱氮性能差、细菌生物活性低,通过对比实验探究其快速重启措施。结果显示,反应器3运行13 d后恢复脱氮性能,NH4+-N和NO2--N的去除率分别为92.5%、85.7%;运行46 d,容积负荷及去除速率分别为0.34 kg/(m3·d)和0.25 kg/(m3·d),NH4+-N、NO2--N、NO3--N的反应速率化学计量比为1.0:1.29:0.19。反应器1在第51天恢复脱氮性能,运行83d,获得容积去除速率0.36kg/(m3·d);反应器2在第20天恢复脱氮性能,运行57 d,获得容积去除速率0.23 kg/(m3·d)。研究表明,相比高基质含量短HRT和低基质含量短HRT,低基质含量长HRT是快速重启反应器的优选措施。This study is based on three oceanic anaerobic bioreactors by high-strength ammonium nitrogen shock loading. As the performance of denitrification is bad and bacterial activity low, we would explore its quick restart method in contrast with test measures. The results showed that the denitrification performance of reactor 3 recoverd in 13 d. The removal rates of NH4＋-N and NO2--N were 92.5% and 85.7% respectively. The volume loading and removal rates of the reactor were 0.34 kg/（m3·d） and 0.25 kg/（m3·d） respectively; while NH4＋-N：NO2--N：NO3--N were 1.0：1.29：0.19 in 46 d operation. But the reactor 1 restored its denitrification performance on the 51 st day; the volume removal rates was 0.36 kg/（m3·d） for running 83 d. In the mean time the reactor 2 restored its denitrification performance on the 20th day; the volume removal rates was 0.36 kg/（m3·d） for running 57 d. The study indicated that low substrate concentration-long HRT is the best choise of the quick restart reactor compared with the high concentration-short HRT and low concentrationshort HRT.
