摘要对北京市通州区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，COD_cr，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, COD_cr, 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.
