摘要
利用被动差分吸收光谱(DOAS)监测仪于2012年夏季对重庆市及周边重点工业园区开展连续移动观测,获取园区内SO2,NO2柱浓度空间分布,结合排放特征和特定气象场确定污染源月排放通量,以判断不同园区污染物排放大小,结果表明广安电厂当月排放的SO2量最大,合川电厂排放的NO2量最大,九龙坡电厂区排放SO2量和NO2量最小。利用Calpuff模型模拟各重点工业园排放对重庆市主城区2012年7月空气质量SO2、NO2影响,结合主城区空气质量自动监测站点浓度均值,研究各污染源对主城区空气质量的贡献率。研究表明,各工业园区对主城区SO2、NO2的贡献率为九龙坡区电厂区域>合川工业园>珞璜电厂>广安电厂。
Source emissions of Chongqing Industry Parks in summer of 2012 was continuous observed using DOAS, the spatial distribution of column concentrations of SO2 and NO2were observed, combined with meteorology and characteristics of emissions to obtain annual emission fluxes. The results showed the maximum emission of SO2 was from Guang'an power plant, which of NO2 was from Hechuan power plant, and Jiulongpo power plant had the minimum emissions of SO2 and NO2.By simulating the influence on air quality of SO2 and NO2of summer in 2012 in Chongqing urban area from chemical plants emissions using Calpuff mode, the contributions to air quality of Chongqing urban from the emissions were found. It showed that Jiulongpo power plant district had the max contributions, while the Guang'an power plant had the min contributions.
