京津冀地区钢铁行业高时空分辨率排放清单方法研究

针对目前京津冀地区钢铁行业大气污染物排放量基数不清,排放清单缺失的现状,以钢铁行业调研、企业在线监测、污染源调查等数据为基础,综合考虑钢铁行业具体工艺设备、环保措施、产能等信息,按照自下而上的方法建立了一套高时空分辨率排放清单.经计算,2012年京津冀地区钢铁企业排放SO2为47.16万t,NOx为37.22万t,烟粉尘为34.15万t,其中烧结和高炉工艺为京津冀钢铁行业污染物的主要来源;从空间分布来看,唐山、邯郸两地区集中了整个京津冀地区一半以上的钢铁企业,其污染物排放量占到了整个区域钢铁企业排放总量的一半以上.

Emission inventory with high temporal and spatial resolution of steel industry in the Beijing-Tianjin-Hebei Region

Aiming at the situation of the unclear air pollutants emission of the steel industry in the Beijing-Tianjin-Heibei Region, and lacking of research on steel industry emission inventory, an emission inventory which is routing-based, from bottom to top and high temporal and spatial resolution of steel industry in the Beijing-Tianjin-Hebei Region was developed based on the data of the steel industry research, on-line monitoring and investigation of pollution sources, considering the concrete information of process equipment, environmental protection measures, productivity of the steel industry. In the research, the air pollution emissions of steel industry in the Beijing-Tianjin-Hebei Region in 2012 were calculated: SO2 was 47.16 kt, NOx was 37.22 kt, PM10 was 34.15 kt. Sintering and blast furnace units are the main air pollution emission sources. Air pollution emissions of steel enterprises in Beijing-Tianjin-Hebei region are unbalanced and mainly concentrated in Tangshan, Handan of Heibei province. Emission load and number of steel enterprise of Tangshan and Handan exceeded over 50% of the all region.
