The Migration Mechanism of Arsenic Ions Under the Effect of Temperature in Yunnan Laterite

This article considers the temperature influence of pollution transportation base on the transportation model of pollution in groundwater to finish the article by using Macro and micro method, the combination of theoretical analysis, experimental research methods and numerical simulation. Established the transportation model for consider temperature and solved by soft of Femlab. The result shows that the more close to the pollution source, the concentration is larger, the farther away from the source of pollution; the concentration value is small, which is consistent with the trend of pollution in the general case. With the increase of temperature, the concentration of pollution increased, among them, the higher the temperature, the rising trend is more obvious, that the migration and diffusion of pollution in the role of temperature. The temperature could increase depth of pollution diffusion. The results will also provide theoretical guide and technological support for the sustainable development of Yunnan economy and ecology as well as for the future laboratory experiments.
