【摘要】：基于WRF-CAMx空气质量模型,定量模拟了火电行业主要大气污染物排放对全国城市环境空气质量的影响.结果表明,火电行业对全国城市SO_2、NO_2、PM_(2.5)、硫酸盐、硝酸盐及一次PM_(2.5)年均浓度平均贡献率分别为15.6%、19.6%、8.5%、11.7%、12.0%和5.2%,并呈现空气污染越重地区,火电行业污染贡献率越低的总体特征.其中,京津冀鲁豫、长三角、以武汉城市群及长株潭城市群为中心的两湖平原地区、成渝地区中大部分空气污染最为严重的区域,火电行业对PM_(2.5)年均浓度的贡献率低于8%.因此,火电行业对环境空气质量的影响总体较小,在深化火电行业污染减排的同时,必须强化非电力行业多污染物协同控制.
[Abstract]:Based on the WRF-CAMx air quality model, the effects of the main atmospheric pollutants emission from thermal power industry on the air quality of urban environment in China are quantitatively simulated. The results show that the thermal power industry has a significant influence on the national cities so _ 2O _ 2O _ 2 / PMSP _ 2, sulfate, and so _ 2O _ 2O _ 2O _ 2P _ P _ 2. The average annual contribution rate of nitrate and PMX 2.5) is 15.619.6and 8.50.11.70.12.0% and 5.2%, respectively. The heavier the air pollution, the lower the contribution rate of thermal power industry. Among them, Beijing-Tianjin-Hebei, Luyu, Yangtze River Delta, In the plain area of two lakes with Wuhan urban agglomeration and Changsha-Zhuzhou-Xiangtan urban agglomeration as the center, most of the regions in Chengdu-Chongqing area have the most serious air pollution, and the contribution rate of thermal power industry to the average annual concentration of PMSP 2.5) is lower than 8%. The influence of thermal power industry on ambient air quality is generally small. While deepening the emission reduction of thermal power industry, it is necessary to strengthen the coordinated control of multi-pollutant in non-power industry.
