摘要
以浙江制革企业退役场地A和B为研究对象,本文对场地内不同区域土壤样品进行采集与测定分析。结果表明,铬和六价铬是制革企业退役场地的特征污染物;土壤中六价铬占总铬比例为1%左右,远小于铬渣污染地块中六价铬占比2.0%~33.3%;废水处理区等生产区域的表层土壤重金属污染较为严重。
This paper takes the decommissioning sites A and B of Zhejiang tannery as the research object, and collects and analyzes the soil samples in different areas of the site. The results show that chromium and hexavalent chromium are characteristic pollutants in the decommissioning sites of tanneries;the proportion of hexavalent chromium in the soil to total chromium is about 1%, which is much smaller than the proportion of hexavalent chromium in the contaminated plots of 2.0%~ 33.3%;heavy metal pollution in the surface soil of production areas such as wastewater treatment areas is more serious.
