摘要:
通过实验室模拟试验,分析了进水碳氮比(carbon-nitrogen ratio,CNR)对污水地下渗滤系统(subsurface wastewater infiltration system,SWIS)脱氮效果及N2O产率和转化率的影响。结果表明,随着CNR的增加,系统对 NH4+-N 及TN的去除率呈下降趋势。当CNR为4时,生物脱氮作用产生的N2O产率较低;当CNR为6时,N2O气体产率达到最高值。N2O转化率随CNR增加呈上升趋势,最大值出现在CNR为10时,N2O转化率为(0.41±008)%;当CNR为4时,N2O转化率最小,为(0.14±0.04)%。综合考虑SWIS的脱氮效果及N2O的产率和转化率,建议在工程应用中,SWIS的进水CNR区间为4~6。
