The study of transportation regularity for different element

This article considers the Pb and Fe influence of pollution transportation base on the transportation model of pollution in groundwater, established the transportation model, solved by soft of Femlab. The result shows that at the same point, the pollution concentrations building up with time prolong; at the same time, the most pollution concentration was pollution source. Along with the increase of pollution sources distance away, decreasing pollution concentration; the transportation of Pb and Fe has the same diffuse trend; the concentration of Fe was larger than Pb for the source sink term was considered of Fe. It is evident that have got Fe supply. So the calculation was more preciseness than Pb.
