Impact on Air Quality of Beijing City by Controlling the Consumption of Coal-Fired

  • 摘要:

    根据清洁空气行动计划,北京市将继续调整能源结构,新建天然气热电中心替代燃煤发电,并且进行工业锅炉煤改气、居民供暖煤改电、远郊区炊事用气改造等措施,以减少煤炭的使用量. 采用自下而上的排放因子法,估算减少燃煤所产生大气污染物(TSP、PM10、一次PM2.5、SO2、NOx及VOC)的减排量,并利用ADMS-Urban模型模拟其对环境空气质量的改善. 结果表明:①2015年北京市煤炭控制在1500×104t以内,测算的煤炭减量为863.38×104t,TSP、PM10、一次PM2.5、SO2、NOx和VOC的减排量分别为2580.17、2032.94、1183.53、6265.30、7220.90和1058.44t. ②各污染物减排空间分布基本一致,主要集中在城市功能拓展区,包括石景山、朝阳区、海淀区和丰台区等,上述区域对TSP、PM10、一次PM2.5、SO2、NOx和VOC削减贡献分别达到78.3%、81.5%、82.7%、85.2%、83.0%和49.9%. ③ADMS-Urban模型模拟结果表明,减少燃煤可使环境空气中ρ(TSP)、ρ(PM10)、ρ(一次PM2.5)、ρ(SO2)、ρ(NOx)和ρ(VOC)分别降低0.55~12.74、0.44~10.78、0.27~6.77、0.78~17.31、1.67~43.48和0.17~12.07μg/m3.
