Abstract

This paper describes a purification method of Cr(VI)-contaminated soil with low environmental load using fermentation of organic matter. There are several remediation technologies and these are usually high cost. A remediation method by using aerobic or anaerobic fermentation is applied. The effect of composting with aerobic or anaerobic fermentation was discussed based on the test results. It is concluded that the anaerobic fermentation with organic matter, effective microorganisms resources, and leaf mold is very effective for remedying the contaminated soil with hexavalent chromium.
