摘要
完善污染物扩散基本方程,结合多组分扩散理论针对湿度变化对气体污染物扩散的影响进行研究,通过对气体污染物迁移、转化的基本方程进行修正,得到在无边界大气条件下1个稳定污染点源连续排放的扩散模型,并对方程进行了简化和求解;通过变湿度气态物扩散特性试验装置,对不同湿度条件下气体扩散性质进行了试验确定,得到了湿度变化条件下气体污染物扩散的一般规律。
The purpose of this study is to investigate the effects of relative humidity on the atmospheric dispersion of air pollutants. A physical and mathematiccal air pollution model under the condition of changing relative humidity based on the theoy of complex component dispersion was established. The numerical solution of the model shows how relative humidity change affects the air pollution. A test was also established to investigate the general rule of the atmospheric dispersion experimentally. It is concluded that the model can also be used in estimating the air pollution.
