摘　　要：为了研究以海绵作填料进行厌氧氨氧化反应的可行性,在某上流式厌氧固定床反应器中利用人工配制高NH4-N水进行了实验研究.结果表明,利用人工配制废水作为实验用水,在水力停留时间为3.1 h,容积负荷为3.5 kg/(m3.d)时,总氮的去除率可达到75%.稳态运行时,反应器内部呈碱性,NH4-N去除量、NO2-N去除量与NO3-N的生成量之间的比值为1∶1.21∶0.19.以海绵作填料,与其他填料(新型丙烯酸纤维、聚乙烯醇凝胶)相比,所需启动时间短,操作简便,并能在较短的水力停留时间内高效地处理高浓度的NH4-N废水.In order to study the feasibility of using sponge as carrier and applying it for ANAMMOX research,experiments were carried out in an up-flow column reactor with synthetic high nitrogen wastewater as influent.The operational results showed that the TN removal efficiency as high as 75% was obtained at a high volumetric loading rate of 3.5 kg/(m3·d) and a short HRT of 3.1 hours with the synthetic wastewater as the influent.At steady operation,the liquid pH value in the bioreactor was alkaline.The ratio of NH4-...
