摘要:
邯郸作为"2+26"城市主要的重工业城市之一,位于京津冀南北传输通道的核心位置,在京津冀地区大气污染协同调控中处于重要地位.为改善当地空气质量,以邯郸市为研究对象,基于拉网式调查获取详细活动水平数据,结合相关排放因子,得到2016年邯郸市大气污染源排放清单;采用WRF-CMAQ(气象-空气质量)数值模型,模拟了2016年典型季节代表月(1月、4月、7月、10月)的空气质量,验证了数值模型的准确性;最后基于总量校验方法,反向估算了邯郸市典型污染物的排放总量,对初始大气污染源排放清单进行校验.结果表明:①2016年邯郸市SO2、NOx、TSP、PM10、PM2.5、CO、VOCs、NH3的总排放量分别为78 533、183 126、497 466、258 940、124 637、3 735 355、200 309、187 299 t.②工业源是SO2、NOx、PM2.5、CO和VOCs的主要排放源,分别占总排放量的74.5%、54.5%、30.6%、76.7%和28.1%;无组织扬尘源对TSP、PM10、PM2.5的贡献较大,分别占总排放量的58.5%、43.6%、30.3%;NH3的主要排放源为农畜氨及人体和其他氨,二者排放的NH3占总排放量的96.9%.③总量模型估算得到邯郸市PM2.5、SO2、NO2年排放量分别为152 739、79 405、206 549 t;对比分析校验前、后典型污染物排放发现,校验前的大气污染源排放清单可能低估了PM2.5和NOx的排放量.研究显示,邯郸市污染物排放量较大,工业源为主要排放源,建议相关部门加强对工业源的管控力度.

Abstract:
As one of the ‘2+26’ major heavy industrial cities, Handan City is located in the heart of the north-south transmission channel of the Beijing-Tianjin-Hebei Region, and has a significant impact on the coordinated control of region air pollution. In order to improve the local air quality, this study developed the air pollution emission inventory in Handan City, Hebei Province, based on the detailed field survey of activity data for typical sectors and combined with the studies of emission factors referred by the guideline and previous studies. The WRF-CMAQ model was used to simulate the air quality in the representative months (e.g. January, April, July and October) in 2016, so that the accuracy of this model was verified. Finally, the total emissions of typical pollutants in Handan City was estimated reversely employing the verification method of the total amount model, thus the accuracy of the initial air pollutant emission inventory was calibrated and improved. The results showed that the total emissions of SO2, NOx, TSP, PM10, PM2.5, CO, VOCs and NH3 in Handan City in 2016 were 78,533, 183,126, 497,466, 258,940, 124,637, 3,735,355, 200,309 and 187,299 t, respectively. In addition, industrial source was the main contributor of SO2, NOx, PM2.5, CO and VOCs emission, accounting for 74.5%, 54.5%, 30.6%, 76.7% and 28.1% of the total emissions, respectively. The unorganized dust contributed significantly to TSP, PM10 and PM2.5, accounting for 58.5%, 43.6% and 30.3% of the total emissions, respectively; Ammonia emissions from livestock and humans accounted for 96.9% of the total emissions. The estimated results by the verification method of the total amount model indicated that the annual emissions of PM2.5, SO2 and NOx in Handan City were 152,739, 79,405 and 206,549 t, respectively. In summary, Handan City is mainly characterized by huge pollutant emissions, especially from industrial sources, which means that the relevant environmental regulation should concentrate on the industrial sectors.
