钢铁企业污染场地土壤环境评价与修复研究

Study on Evaluation and Remediation of Polluted Soil Site in and Beside Iron and Steel Enterprises

搬迁企业原址场地(棕地)可能由于原生产活动遗留有毒有害物质的污染,因此,棕地改造之前必须对其进行污染调查分析和环境风险评价,判断其是否需要进行土壤修复。采用磁学测量结合土壤理化分析对首钢搬迁场址进行了土壤污染调查,用克里格法插值后采用内梅罗指数法评价土壤环境风险,并列举了不同生产区域的主要污染物和相应的土壤修复方法。

The brownfield maybe polluted by production,so soil pollution investigation and assessment is the first issue to be solved.Shougang brownfield has been investigated by the way of magnetic proxies and analysis of soil physico-chemical properties.The environmental risk is assessed by Nemerow index after Kriging interpolation and it lists key pollutants and corresponding solutions of soil remediation from different producing areas.
