中文摘要 |
为探究安阳市PM2.5排放特征,通过现场调查对安阳市工业源活动水平和控制技术信息进行收集,采用合理的估算方法、排放因子,建立了安阳市2016年工业源PM2.5排放清单,并利用地理信息系统(GIS)技术进行空间分配.基于典型行业超低排放改造和煤炭压减要求设置3种情景,估算了2020年安阳市工业源PM2.5减排潜力.结果表明,安阳市2016年工业源PM2.5排放总量为81071.13 t;有色冶金、钢铁和建材行业是安阳市PM2.5主要贡献源,分别占总排放量的45.43%、25.74%和18.00%;安阳市各乡镇排放差异突出,PM2.5排放主要集中在市区及林州市和安阳县,且以安阳市区排放量最为突出,而安阳市区的4个辖区的排放强度差异更为巨大;通过设定不同控制情景,估算2020年安阳市PM2.5减排潜力分别为398.72、11623.87和14072.27 t,分别占2016年工业源排放总量的0.49%、14.34%和17.22%.可见,安阳市PM2.5具有较大减排潜力,超低排放改造和煤炭压减对安阳市PM2.5减排具有重要意义. |
英文摘要 |
To investigate the characteristics of PM2.5 emissions in Anyang, the PM2.5 emission inventory from industrial sources of Anyang in 2016 was established based on reasonable estimation method and emission factor. The spatial distribution analysis was carried out using Geographic Information System (GIS) technology. Based on the industry's typical ultra-low emission transformation and coal pressure reduction requirements, three scenarios were set to estimate the PM2.5 emission reduction potential of industrial sources from Anyang in 2020. The results show that the total PM2.5 emissions from industrial sources in Anyang was 81071.13 t in 2016. Non-ferrous metallurgy, iron and steel, and building materials industries were the main contributing sources, accounting for 45.43%, 25.74%, and 18.00% of the total emissions, respectively. The emission differences between towns and within Anyang were outstanding. The PM2.5 emissions were mainly concentrated in urban areas, Linzhou City, and Anyang County. The emissions in Anyang City were most prominent, while the emission intensity differences between the four jurisdictions of Anyang City were even greater. In the three different control scenarios, the potential for PM2.5 emission reduction in Anyang in 2020 was estimated to be 398.72, 11623.87, and 14072.27 t, accounting for 0.49%, 14.34%, and 17.22% of the total industrial source emissions in 2016, respectively. It can be concluded that Anyang has a great potential for PM2.5 emission reduction. In addition, ultra-low emission reform and coal pressure reduction can be of great significance for PM2.5 emission reduction in Anyang. |
