摘　　要：试验采用同时好氧缺氧反应器处理垃圾压缩站废水。试验结果表明,反应器对垃圾压缩站废水的CODCr、NNH4+-N和TN具有较好的处理效果。试验过程中,CODCr,NH4+-N和TN的平均去除率分别为71.30%,87.50%和67.76%。电子计量学研究表明,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。微环境和宏观环境理论表明,反应器具备厌氧氨氧化反应发生的条件。Effect on city environment was caused by sewage of low C/N produced by garbage compressing spot, but relative processing study had not been carried out. Sewage of garbage compressing spot was treated with the simultaneous oxic and anoxic bioreactor in the test. Well effect of CODcr NH^＋4-N and TN removal being achieved in the bioreactor was discovered. The averaged removal efficiencies of CODcr, NH^＋4-N and TN of 71.30%, 87.50% and 67.76% were achieved in the bioreactor during the course of the test, respectively. Removal efficiency of TN being significantly affected by the value of influent CODcr/TN had been discovered during the course of the test. It was demonstrated that there exists other reactive forms of nitrogen removal which cost less carbon source than traditional thort-cut denitrification based on the research of electron metrology and the conditions in favor of anaerobic ammonium oxidation occurring according to the theories of microenvironment and macroscopic environment.
