| 摘 要： | 为考察不同反应器类型对N_2O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N_2O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N_2O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N_2O主要产生于硝化阶段,不同生物反应器类型对脱氮过程中N_2O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N_2O产生量分别为0.76和1.48 mg/L,SBR生物反应器硝化过程中N_2O产生量远低于HBR生物反应器N_2O产生量. |

| Abstract: | To investigate the effect of different types of bioreators on N_2O production.N_2O 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 N_2O production in nitrogen removal was investigated mainly.In the SBR system,N_2O was mainly produced in nitrification.N_2O production in HBR and SBR nitrification was 0.76 mg/L and 1.48 mg/L,respectively.Under the condition of the SBR bioreactor,N_2O production was obviously lower than that in the HBR bioreactor. |
