乌鲁木齐市非金属矿物制品业大气污染物排放清单与时空分布

基于乌鲁木齐市各类非金属矿物制品业的活动水平数据及其排放因子，建立了2015年乌鲁木齐市3种大气污染物的排放清单。2015年乌鲁木齐市非金属矿物制品业大气污染物NO_x、SO₂和PM_2.5的排放总量分别为1.17×10⁴ t、1.63×10⁴ t和8.35×10³ t。混凝土配料行业是NO_x和SO₂的主要排放源，占比分别为56.77%和71.72%；PM2.5的排放源主要是水泥（干法）行业，占比为70.23%。米东区是对NO_x、SO₂和PM_2.5排放量的最大贡献区域，头屯河区是NO_x和SO₂的第二大贡献区域，达坂城区是PM_2.5的第二大贡献区域。污染物在5~9月处于排放高峰期。蒙特卡罗法模拟结果表明，混凝土配料制品行业95%置信区间的不确定性最高，为-72%~157%。

Emission inventory and temporal-spatial distribution of air pollutants from non-metallic mineral products industry in Urumqi

Based on the activity level data and emission factors in non-metallic mineral products industry in Urumqi，the emission inventory of 3 air pollutants in Urumqi for 2015 were established. In 2015，the total emissions of NOx，SO2 and PM2.5 in air pollutants from non-metallic mineral products industry in Urumqi were 1.17×10⁴，1.63×10⁴，8.35×10³ t，respectively. The main emission sources of NO_x and SO₂ were concrete batching，accounting for 56.77% and 71.72%. PM_2.5 emissions were mainly related to cement industry（dry method），with contribution rate of 70.23%. In addition，Midong District was the largest contributor to NO_x，SO₂ and PM_2.5 emissions. Toutunhe District was the second largest contributor to NO_x and SO₂，and Dabancheng District was the second largest contributor to PM_2.5. The peak period of pollutant emission was from May to September. The simulation results by Monte Carlo method showed that the largest uncertainty with the 95% confidence interval was from concrete batching of -72%-157%.
