Abstract :
The main purpose of the research is to study the influence on shallow ground water by heavy metal in polluted river. In the lab-scale experiment polluted rivers were simulated by domestic sewage, and three kinds of natural sand were chosen as infiltration medium, it was found that Cr(VI) penetrated on the 13th day and then had a removal ratio of 77-99% in coarse sand, over 91% and 96% in two kinds of medium sand. The mechanism of Cr(VI) removal is reducing action and sedimentation. Cr(VI)mainly is transformed to precipitation by reducing action because of abundant reduction agent in the infiltration media.
