Comparison Analysis of Accounting and Monitoring of Particulates Fugitive Emissions from an Iron and Steel Enterprise
摘要
Abstract
In this paper, a large iron and steel enterprise in the eastern old industrial area of Jinan City was taken as an example. On the basis of pre-phase investigation and emission coefficients, the discharged amount of total suspended particulates (TSP) was calculated. Then, relevant formula was used to calculate the ground concentrations of TSP around the plant at different distances. The ground concentrations and the monitoring values of TSP around the plant were analyzed, fully confirming the accuracy and feasibility of the Gaussian model of continuous point source diffusion. With the airflow passing through the plant, in the direction from the upwind to the downwind, TSP concentration at the monitoring sites increased rapidly (by 1.04 times), and downwind TSP concentration exceeded 1.32 times of the secondary level. Variation of the ground concentrations of TSP in the plant at different distances was obvious. From the distance of 0.1 km to 10 km, the ground concentrations were diluted about 3500 times. When the distance exceeded 4 km, the impact of fugitive emission of TSP on the surrounding ambient air quality was limited.关键词
