    • 摘要: 海绵作填料在上流式厌氧固定床反应器中厌氧氨氧化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.

       

      Abstract: 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-N removal,NO2-N removal and NO3-N production are 1∶1.21∶0.19.Compared with other carriers(Biofill and PVA-gel),the start-up period for the reactor of sponge as carrier is shorter,and the operation is simple.And also it showed potential for treatment of wastewater with high concentrations of NH4-N using a short hydraulic retention time.
