The invention provides a reclamation method for hexavalent chromium contaminated soil. The reclamation method comprises the processes of reducing hexavalent chromium in the contaminated soil and preparing building bricks with the soil as raw materials. According to the content of the hexavalent chromium in the soil, the hexavalent chromium is reduced to trivalent chromium with low toxicity with ferrous sulfate as a reducing agent, and then the trivalent chromium is used for preparing the bricks. According to the reclamation method for the hexavalent chromium contaminated soil, not only is the leaching concentration of the hexavalent chromium in the soil reduced, but also the soil is taken as one of the raw materials for preparing the bricks. The prepared bricks are used as building materials and thus harmless disposal and reclamation of the hexavalent chromium contaminated soil are achieved.
