摘　　要：采用3个相同的生物滤池,分别接种好氧硝化生物膜、厌氧反硝化生物膜、厌氧反硝化生物膜+厌氧活性污泥混培物,常温条件下,通入pH值为7.5的模拟低氮废水,分别经过129、100和129 d,3个缺氧氨氧化生物滤池均成功启动。装置运行进入稳定期后,通过减少水力停留时间、提高氮负荷的方法,加快缺氧氨氧化菌富集,并研究其脱氮能力。启动成功后,3个生物滤池对总氮的平均去除率分别为55%、65%和65%,平均容积负荷分别为0.03、0.07和0.035 kgN/(m3·d),其中接种厌氧反硝化生物膜的生物滤池启动最快、性能最好。Aerobic nitrification biofilm, anaerobic denitrification biofilm and mixture of anaerobic denitrification biofilm and anaerobic activated sludge were inoculated in three identical biological filters. At room temperature, the three ANAMMOX biofilters with simulated low-nitrogen wastewater of pH 7.5 successfully started after 129, 100 and 129 d, respectively. After entering a stable operation period, denitrification capacity was further studied by reducing hydraulic retention time, improving nitrogen load, and speeding up the enrichment of anoxic ammonia-oxidation bacteria. After a successful startup, the average total nitrogen removal rates were 55% , 65% and 65% , and the average volumetric loadings were 0.03, 0.07 and 0. 035 kgN/（ m^3 · d ） respectively. The anaerobic denitrification biofilm biofilter achieved the fastest and best performance.
