摘　　要：采用SBR系统处理城市垃圾渗滤液,研究了不同C/N、DO和MLSS对同时硝化反硝化脱氮效率的影响。结果表明:总氮去除率随着C/N、MLSS升高而上升;DO越低,总氮去除率越高;当进水CODCr与NH3-N浓度分别为420 mg/L和112 mg/L,DO和MLSS分别为1.5 mg/L和5016 mg/L时,CODCr、NH3-N及TN去除率分别为81.54%、96.57%和46.66%。根据试验结果,对同时硝化反硝化一个代表周期作了分析。Urban landfill leachate was treated by seqiemcing batch reactor （SBR） system, The influence of various C/N, DO and MISS concentrations on the process of simultaneous nitrification and denitrification was studied. The results show that under the experimental conditions the removal rate of total niurgen had a tendency to rise with the increase of C/N and MISS. In addition, the lower the DO, the higher the nitrogen removal rate. When the conoentrations of CODCr, NH3-N, DO and MLSS were 420mg/L, 112 mg/L, 1.5 mg/L and 5016 mg/L, respectively, in influent, the removal rates of COECr, NH3-N and TN were 81,54%, 96.57 % and 46.66 % respectively. One typical cycle of SND was analyzed on the basis of the results.
