电碳原料焙烧烟尘污染对大气质量的影响评价体系构建研究

Construction of an Evaluation System for the Impact of Smoke and Dust Pollution from the Roasting of Electric Carbon Raw Materials on Atmospheric Quality

由于电碳原料焙烧产生的烟尘中包含大量的污染物,直接影响大气质量。为此,本研究构建提出电碳原料焙烧烟尘污染对大气质量的影响评价体系。以辽宁省地区为研究区域,选取电碳原料焙烧烟尘污染下的空气质量指数衡量大气质量,将电碳原料焙烧烟尘中包含的臭氧、PM_(2.5)、二氧化氮、PM_(10)、一氧化碳和二氧化硫作为主要指标,将气温、风速、湿度和气压气象因素作为次要指标,建立大气质量影响评价体系,采用灰色关联分析法获取主要指标与次要指标之间的相关程度。结果表明:电碳原料焙烧烟尘污染对大气质量具有显著影响,首要污染物为PM_(2.5)。

Because the soot produced by the roasting of electric carbon raw materials contains a lot of pollutants,it directly affects the air quality.To this end,this study establishes an evaluation system of the impact of soot pollution from the roasting of electric carbon raw materials on air quality.Taking Liaoning Province as the study area,the air quality index(AQI)under the pollution of roasting soot of electric carbon raw materials was selected to measure the air quality.Ozone,PM_(2.5),nitrogen dioxide,PM 10,carbon monoxide and sulfur dioxide contained in roasting soot of electric carbon raw materials were taken as the main indexes,and meteorological factors such as air temperature,wind speed,humidity and barometric pressure were taken as the secondary indexes.The air quality impact assessment system was established,and the correlation degree between primary and secondary indexes was obtained by using grey correlation analysis method.The results show that the smoke pollution from the roasting of electric carbon raw materials has a significant impact on the air quality,and the main pollutant is PM_(2.5).
