摘要：
The atmospheric simulation software AERMOD was used to predict the transmission and diffusion of SO2 in different emission scenarios of a 1 000 MW coal-fired unit in order to analyze the effect of SO2 ultra-low emission reduction on the surrounding environment. The mass concentration distribution was quantified calculation. Results show that the maximum mass concentration of SO2 in the ambient air is reduced by more than 82% by the “ultra-low emission” project while the accounting for standard rate goes down substantially. The pollutant mass concentration in the peak distribution area and the mean value of the accounting for standard rate of each time period are controlled. The contaminant concentration index of each time period and its distribution gradient are synchronously reduced. Since the flue gas lift height is high, the concentration of areas within 1 km of emission source is low. “Ultra-low emission” projects decrease the environmental impact of SO2 emissions, and obviously improve the air quality of the surrounding environment. © 2017, Zhejiang University Press.
