摘要：采用单级SBR系统处理含有机物和氨氮的模拟污水并研究了单级生物脱氮的主要影响参数。实验采用葡萄糖作为碳源、硫酸铵作为氮源,研究了不同的CN和DO对同时硝化反硝化作用的影响。研究结果表明,当进水CODCr、NH3N浓度分别为244～500mgL和45.4～52.2mgL、反应条件为DO=1.0～3.0mgL、CODCrNH3N=5～10时,反应器中CODCr、NH3N的去除率分别达到87.1%～91.0%、75.1%～94.7%。根据试验结果,对同时硝化反硝化过程的一个代表性周期进行了分析。
A single stage SBR system fed with a synthetic municipal wastewater containing organics and ammonia was investigated.By the addition of glucose as carbon source and ammonium sulfate as nitrogen source,the influences of varieties of C/N and DO concentration on simultaneous nitrification and denitrification (SND) were also investigated.The results showed that when the influent concentrations of COD_ Cr and NH_3-N were 244～550 mg/L,45.4～52.2 mg/L,DO=1.0-3.0 mg/L and COD_ Cr/NH_3-N=5～10 respectively,the removal rates of COD_ Cr and NH_3-N reached 87.1%～91.0%, 75.1%～94.7% respectively.Considering the research results,one typical cycle of SND was analyzed simultaneously.
