摘　　要：自下而上建立2018年中国高分辨率钢铁企业大气污染物排放清单(HSEC,2018),定量模拟中国钢铁企业2018年和未来年情景下排放各种大气污染物对环境的影响情况.结果表明:2018年,中国钢铁行业共排放SO2、NOx、PM(10)、PM(2.5)、PCDD/Fs、VOCs、CO、BC、OC、EC、氟化物分别为29.02万t、66.57万t、28.73万t、11.69万t、2.24kg、89.21万t、4057.49万t、0.45万t、0.61万t、0.06万t、0.88万t,焦化、烧结、球团、高炉4个铁前工序是中国钢铁行业大气污染物主要排放环节,中国钢铁行业对各省份SO2、NOx、PM(2.5)年均浓度贡献比例平均值分别为2.85%、3.37%、1.54%;未来年,中国钢铁企业SO2、NOx、PM(10)排放量分别为4.94万t、7.58万t、4.11万t,分别下降了82.98%、88.61%、85.69%,中国钢铁行业对各省份SO2、NOx、PM(2.5)年均浓度贡献比例平均值分别为0.31%、0.22%、0.02%.In this study,a high-resolution steelmaking plants emission inventory for China(HSEC,2018)was established to quantitatively simulate the environmental impact of various atmospheric pollutants emitted by Chinese iron and steel plants in 2018 and in the future years.The results showed that in 2018,the total emissions of SO2,NOx,PM10,PM2.5,PCDD/Fs,VOCs,CO,BC,OC,EC and fluoride were 290.2kt,665.7kt,287.3kt,116.9kt,2.24kg,892.1kt,40,574.9kt,4.5kt,6.1kt,0.6kt and 8.8kt,respectively.Coking,sintering,pelletizing and blast furnace are the primary emission sources in Chinese iron and steel industry.Furthermore,Chinese iron and steel industry contributed 2.85%,3.37%and 1.54%,respectively,to the average annual concentrations of SO2,NOx and PM2.5 in each province.In the future situation,the emissions of SO2,NOx and PM10from China's iron and steel plants will be 49.4kt,75.8kt and 41.1kt respectively,decreasing by 82.98%,88.61%and 85.69%,respectively.The corresponding contributions of Chinese iron and steel industry to the annual average concentration of SO2,NOx and PM2.5in each province will be 0.31%,0.22%and 0.02%in this case,respectively.
