摘要: 为支撑京津冀及周边地区燃煤电厂煤场无组织颗粒物深度治理工作,以2017年为基准年、以总悬浮颗粒物(TSP)为指标分析了燃煤电厂煤场无组织颗粒物时空变化特征,基于相关政策设计了防风抑尘网改造和全封闭改造两个控制情景并分别分析了其控制效果。结果表明:2017年京津冀及周边地区城市燃煤电厂煤场无组织颗粒物排放量为3 044.41 t,冬春季(1—5月)是开展煤场无组织颗粒物排放治理的关键期。煤场全封闭改造可减排98.33%的煤场无组织颗粒物。从局地环境质量改善角度考虑,燃煤电厂煤场无组织颗粒物治理较有色烟羽改造更具性价比。建议重视区域内燃煤电厂煤场无组织颗粒物排放控制工作,抓住治理关键期,有序、分步开展煤场全封闭改造。

Abstract: In order to support the in-depth control of fugitive particulate matter emissions in the coal yard of coal-fired power plants in Beijing-Tianjin-Hebei and surrounding areas, by taking the data collected from the year of 2017 as the baseline and the total suspended particulate (TSP) as the research objective, the temporal and spatial variation characteristics of fugitive particulate matter emissions from the coal yard of coal-fired power plants are explored. Based on relevant policies, two scenarios with different approaches are designed and their control effects are analyzed respectively, i.e., porous fences reconstruction and fully enclosed reconstruction. The results show that in 2017, there were 3 044.41 tons of fugitive particulate matter emitted from the coal yards in the above areas. Winter and spring seasons (from January to May) are the critical time period for the control of fugitive particulate matter emissions. With the approach of total enclosure reconstruction, the fugitive particulate matter emissions can be reduced by 98.33% from coal yards. From the perspective of improving the local environmental quality, emission control of the fugitive particulate matter in coal yards is more cost-effective than that of “colored plume” reduction. At last, it is suggested to attach significance to the control of fugitive particulate matter emission in the coal yard of regional coal-fired power plants. Also by seizing the critical period of environmental management, the fully enclosed reconstruction of coal yard should be carried out in an orderly and step-by-step manner.
