减少化石能源产生的致霾大气排放物分析探讨

通过分析化石能源使用时通过烟气和水蒸气向大气中排放的大量二次复合细颗粒物的前体物、水溶性离子、水蒸气等致霾大气排放物,在雾霾易发气象条件下,这三类致霾大气排放物在较低的大气边界层内相互作用,形成细颗粒物质量农度快速提高的正反馈机制,得出致霾大气排放物是雾霾形成的主要来源物。雾霾发生时区域内新能源的可用性显著下降,形成的电力缺口通常由化石能源替代,不能明显减轻雾霾程度,因此治霾之本是要减少化石能源产生的致霾大气排放物。

With the consumption of fossil energy,a large number of precursors of secondary composite fine particles,water-soluble ions,water vapor and other haze-induced atmospheric emissions are emitted into the atmosphere through flue gas and water vapor.Under the meteorological conditions of haze,these three types of atmospheric emissions interact in the lower atmospheric boundary layer,forming a positive feedback mechanism with rapid increase in mass concentration of fine particles.It is concluded that the atmospheric haze-induced emissions are the main source of haze formation.When haze occurs,the availability of new energy in the area is significantly reduced,and the resulting power gap is usually replaced by fossil energy,which does not significantly reduce the degree of haze.The key to tackling haze is to reduce the atmospheric haze-induced emissions from fossil energy.
