    SBR和HBR两种反应器中N2O产生量的研究

    Research on N2O Production in SBR and HBR Bioreactor

      摘要
    • 摘要: 为考察不同反应器类型对N2O产生量的影响.试验采用好氧-缺氧SBR生物反应器和间歇式复合生物反应器HBR(填料填充率:30%,运行方式:瞬间进水—曝气360 min—沉淀40 min—排水20 min),研究实际生活污水脱氮过程中N2O的产生与释放情况,重点考察不同生物反应器类型对脱氮过程中N2O产生量的影响.结果表明,SBR系统处理实际生活污水脱氮过程中N2O主要产生于硝化阶段,不同生物反应器类型对脱氮过程中N2O产生量有显著影响.SBR生物反应器和HBR生物反应器硝化过程N2O产生量分别为0.76和1.48 mg/L,SBR生物反应器硝化过程中N2O产生量远低于HBR生物反应器N2O产生量.

       

      Abstract: To investigate the effect of different types of bioreators on N2O production. N2O production and emission in nitrogen removal process treating real domestic wastewater was studied utilizing oxic-anoxic SBR system and intermittent hybrid biological reactor (HBR), filling rate of 30% and operation mode of instantaneous water inflow, aeration (360 min), sedimentation (40 min) and drainage (20 min). The influence of different bioreactors on N2O production in nitrogen removal was investigated mainly. In the SBR system, N2O was mainly produced in nitrification. N2O production in HBR and SBR nitrification was 0.76 mg/L and 1.48 mg/L, respectively. Under the condition of the SBR bioreactor, N2O production was obviously lower than that in the HBR bioreactor.
