摘　　要：低碳氮比的垃圾压缩站废水处理是一个日益突出且非常棘手的问题,但还未引起关注,本研究采用同时好氧缺氧反应器处理垃圾压缩站废水。结果表明,反应器对垃圾压缩站废水的CODCr、NH4+-N和TN具有较好的处理效果。CODCr、NH4+-N和TN的平均去除率分别为71.30%、87.50%和67.76%。TN去除率受进水CODCr浓度与进水TN浓度比值的影响较大。亚硝酸盐和硝酸盐途径的反硝化化学方程式表明,同时好氧缺氧生物反应器内存在比传统短程反硝化反应消耗碳源更少的脱氮反应形式。絮体微环境和反应器宏观结构表明,反应器具备厌氧氨氧化反应发生的条件。Treatment of low C/N sewage from garbage compressing spot is an increasing and intractable problem which has not yet been concerned. This research is conducted to treat sewage of garbage compressing spots with simultaneous nitrification and denitrification. The results showed that the bioreactor had shown potentials for CODcr, NH4^＋-N and TN removal from the sewage, corresponding to the averaged removal efficiencies of CODcr, NH4^＋-N and TN of 71.30%, 87.50% and 67.76% in the bioreactor, respectively. It is found that removal efficiency of TN was significantly affected by the value of the influent CODCr/TN. There are other reactive forms of nitrogen removal which cost less carbon source than traditional short-cut denitrification based on the stoichiometric equations of denitrification over nitrite and nitrite. According to the theories of microenvironment of the floc and macrostructure of the bioreactor the conditions was in favor of anaerobic ammonium oxidation.
