Abstract :
In this paper, with the 0~100cm soil of Tongliao sewage irrigation farmland for soil column test, we study the vertical distribution of heavy metals of Cr, Cu and Hg in different irrigation concentrations. The result showed that with the increase of irrigation concentration, the distribution of Cr and Cu content is: W1 <;initial <;W2 <;W3 <;W4. While Hg is: W1 <;W2 <;W3 <;W4 <;initial. Vertical migration of heavy metal Cr and Hg were low, and Cu was easy.
