基于CALPUFF模型的沥青路面建设期VOCs扩散模拟研究
Simulation Study of VOCs Diffusion of Asphalt Pavement Construction Period Based on CALPUFF Model
摘要
Abstract
In order to control the diffusion of volatile organic compounds(VOCs)in the asphalt pavement construction period,the diffusion behavior in the atmosphere was investigated.Based on the measured VOCs concentration data of asphalt pavement construction site,the CALPUFF model was adopted to simulate the diffusion to study the diffusion characteristics.The simulation results show that both the wind speed and direction will affect the diffusion charac-teristics of asphalt VOCs in the plain terrain.When the wind speed is higher and uniformly distributed in all direc-tions,it is the most favorable for the diffusion of asphalt VOCs,resulting in a reduction of about 48％in the pollu-tion range and a reduction of 190 μg/m3 in mass concentration at the dispersion point;When the wind speed is smaller and the wind direction is unidirectional,the diffusion of asphalt VOCs will be hindered,resulting in no sig-nificant reduction of the diffusion range of asphalt VOCs.And the mass concentration of diffusion point is reduced by 100 μg/m3.Kendall's W consistency test was used to verify the accuracy of the CALPUFF model.The results showed that the simulated data has a high consistency with the field measured data,indicating that the CALPUFF model can accurately reflect the diffusion characteristics of VOCs during the construction period of asphalt pavement.关键词
