The invention discloses a method for removing heavy metal chromium in a water body. The method comprises the steps of adding nanometre zero-valent iron and ethylene diamino-disuccinic acid in a chromium-containing water body and carrying out a constant-temperature oscillation treatment to finish a treatment for the chromium-containing water body. According to the method disclosed by the invention, the capacity for removing Cr(VI), of nZVI is improved by reducing Cr(VI) into low-toxicity Cr(III) by virtue of the nZVI, and adding a chelating agent EDDS to complex with the Fe(III)/Cr(III) generated in the reaction to prevent the Fe(III)/Cr(III) from co-precipitation on the surface of the nZVI. The method disclosed by the invention has the following advantages: the process is simple, the reaction time is short, the used chelating agent is easy to degrade in an environment, and the like; by adding the EDDS, the removal rate of the nZVI for the Cr(VI) is increased by 20-40%, and meanwhile, the ...
