北京市水泥工业大气污染物排放清单及污染特征

Development of an Air Pollutant Emission Inventory of Cement Industry for Beijing and Pollution Characteristics Analysis

采用排放因子法估算2010年北京市水泥工业颗粒物TSP和气态污染物SO2、NOx、氟化物的排放总量，从而建立了水泥工业大气污染物排放清单，并分析其主要大气污染物排放时空分布特征及对全市总排放量的贡献情况。结果表明：（1）水泥工业NOx污染较为严重，NOx排放占全市总排放量的6．72％；（2）水泥工业作为点源污染，在局部范围内对周围空气及居民有较大的影响；（3）利用ADMS—URBAN模型进行大气污染贡献分析，水泥工业TSP排放对环境空气质量贡献0．100-0．169μg／m3（1h），SOs排放对环境空气质量贡献0.0285-0．0652μg／m3（1h），NOx排放对环境空气质量贡献0．324-0．760μg／ma（1h），NOx对空气质量影响较大。

Emission factor method was used to estimate the emission of total suspended particulates （TSP）, gaseous pollutants such as SO2, NOx, fluoride from the cement industry for Beijing in 2010, an air pollutant emission inventory of cement industry was developed, and spatial and temporal characteristics of the main atmospheric pollutants emission and the contribution of the city＇s total emission were analyzed. Results showed that NOx pollution of cement industry was much serious, with NOx emissions accounting for 6.72% of the city＇s total emission. As point source pollution the cement industry has a greater impact on the surrounding air and residents in the local area. ADMS-URBAN model was used to analyze the contribution of concentration of air pollutants, the TSP emission of cement industry contributed 0.100 to 0.169 μg/m3（1 h） to ambient air quality, SO2 emissions contributed 0.028 5 to 0.065 2μg/m3（1 h）, NOx emissions contributed to 0.324-0.760 μg/m3 （1 h）, and NOx has greater impact on the air quality.
