This study updates a bottom-up high-resolution emission inventory and estimates the concentrations, emission factors, emissions, and performance values of China's power plants, based on the data from continuous emission monitoring systems and environmental statistics in 2018. The results show that the ultra-low emission policy has significant effects: the average concentrations of SO, NO, and PM in thermal power plants were 37.57, 56.71, and 7.41 mg ·m, respectively in 2018, which were 58.71%, 43.12%, and 60.79% lower than those in 2015. The average emission factors of SO, NO, and PM from coal-fired units in China were 0.3, 0.48, and 0.06 g ·kg, respectively, which were 55.2%, 36.84%, and 62.5% lower than those in 2015. The total emissions of SO, NO, PM, and PMin thermal power plants were 721.4, 1183.8, 149.0, and 135.9 kt ·a, respectively, down by 41.32%, 19.29%, 48.12%, and 40.39% from 2015.
本研究更新了一个自下而上的高分辨率排放清单，并基于2018年连续排放监测系统和环境统计数据，估算了中国发电厂的污染物浓度、排放因子、排放量和绩效值。结果表明，超低排放政策成效显著：2018年，火力发电厂SO₂、NOₓ和PM的平均浓度分别为37.57、56.71和7.41mg·m⁻³，分别比2015年降低了58.71%、43.12%和60.79%。我国燃煤机组SO₂、NOₓ和PM的平均排放因子分别为0.3、0.48和0.06g·kg⁻¹，分别比2015年降低了55.2%、36.84%和62.5%。火力发电厂SO₂、NOₓ、PM₁₀和PM₂.₅的总排放量分别为721.4、1183.8、149.0和135.9kt·a⁻¹，较2015年分别下降了41.32%、19.29%、48.12%和40.39%。
