摘要
在采用马尔文粒度分析仪对所选取的4种典型性露天粉尘进行粒度分析的基础上,理论计算了这几种尘粒在风力作用下的扬尘污染范围,从而确定出露天尘源是一种近地面的污染。之后采用近地面尘降模型,计算了这类污染源在不同气象层结下的扩散状况,得出其污染浓度对大气环保浓度的分担率。
The scope of four typical kinds of particles' concentration in air are calculated theorically based on the analyses of granularity results with Malvern instrument so that open-air wind blown particle pollution can be determined. Then, the concentration under different wind diffusion condition are analysized by using ground pollution mode so that the ratio of contribution to the total pollution limit is obtained.
