对北京市通州区H再生水厂采用的A2/O+MBR工艺运行效果与不同环节碳排放特征进行研究.结果表明：2018年该再生水厂对BOD5，CODcr，NH4+-N，TN和TP的平均去除率分别为97.3%，94.1%，98.6%，77.0%，96.2%；全厂碳排放总量和吨水碳排放量呈春夏季节逐渐降低，秋冬季节缓慢升高的特征，全厂综合吨水碳排放量约为2.26kgCO2e/t.碳排放总量中能耗碳排放量占主要地位，CH4，N2O和物耗碳排放量占比较小；统计分析显示CH4，能耗和物耗吨水碳排放量与BOD5，TN进水浓度及BOD5去除率显著相关；N2O吨水碳排放量与TN与BOD5进水浓度显著相关；直接，间接吨水碳排放量与水量无显著相关性.
Abstract
The operation effect and carbon emission characteristics of the A2/O+MBR process in the H reclaimed water plant of Tongzhou District, Beijing, were studied in this paper. The results showed that the average removal rates of BOD5, CODcr, NH4+-N, TN and TP were 97.3%, 94.1%, 98.6%, 77.0% and 96.2% respectively. The total carbon emission and carbon emission per ton of water of the H reclaimed water plant decreased gradually in spring and summer and increased slowly in autumn and winter, the total carbon emission per ton of water was about 2.26kgCO2e/t. In the total carbon emissions, energy consumption carbon emissions accounted for the leading position, while CH4, N2O carbon emissions, and drug consumption carbon emissions accounted for a relatively small proportion. The statistical analysis results showed that the carbon emissions of CH4 ton water, energy consumption ton water, and material consumption ton water were significantly correlated with BOD5, TN influent concentration, and BOD5 removal rate. The carbon emission of N2O per ton of water was significantly correlated with the influent concentrations of TN and BOD5. There is no significant correlation between direct and indirect carbon emissions per ton of water and water quantity.
