| 摘 要： | 在长期运行的处理污泥压滤液的气提亚硝化反应器中发现了单级自养脱氮反应,并形成了具有自养脱氮性能的原生颗粒污泥.以原生颗粒污泥启动并运行了单级自养脱氮反应器,对污泥压滤液进行脱氮处理取得了良好效果.进水总氮浓度为350 mg.L-1左右时,总氮平均去除率为74.81%,最高达86.92%,总氮平均去除负荷(以N计,下同)为0.68 kg.(m3.d)-1,最高达0.90 kg.(m3.d)-1.投加粉末活性炭后单级自养脱氮反应得到强化,运行稳定性得到提高.进水基质浓度、氮负荷及曝气量对自养脱氮反应影响较大.污泥压滤液中的有机物、pH值和碱度对单级自养脱氮反应影响较小.曝气量/ΔTN、曝气量/ΔNH4+-N及ΔALK/ΔTN比值可作为单级自养脱氮反应重要的运行指标.

| Abstract: | Single-stage autotrophic nitrogen removal(SANR) has been observed in a long-term operated nitrosation air-lift reactor for treating digested sludge dewatering effluent from sewage wastewater treatment plant.A kind of so called self-generated granular sludge which undertake the SANR reaction has oriented formed.The performance of SANR reactor cultivated above sludge for treating sludge dewatering effluent has been tested and better results have been reached.When the influent total nitrogen(TN) was kept about... |
