钢铁企业浅层地下水污染与治理研究

Study on Pollution and Treatment of Shallow Groundwater in Iron and Steel Enterprise

搬迁企业原址浅层地下水可能受原生产活动的污染,因此,旧址再利用之前必须进行地下水污染调查分析和环境风险评价,判断是否需要进行地下水修复。该文采用理化分析对首钢某区域及下游某村庄进行了地下水污染调查,采用内梅罗指数法进行地下水环境风险评价,分析了污染来源,并提出采用基于环境风险的地下水污染治理模式及技术经济分析。

The shallow groundwater of former site in removed enterprise may be polluted from steel-making production,so the investigation analysis and environmental risk assessment of groundwater pollution must be carried out before the reuse of former site,then judge whether the groundwater needs to remediation.The groundwater pollution is investigated for Shougang field and the village at lower reaches by physico-chemical analysis,and the environmental risk is assessed for the studied area by Nemerow index,the pollution source is at last found,finally the management model of groundwater pollution based on environmental risk and technical economic analysis are proposed.
