重金属污染地块风险评估及土壤修复技术探析

Risk Assessment of Heavy Metal Contaminated Land and Soil Remediation Technology

重金属会对周围土壤以及地下水造成污染,继而威胁到人体健康。为此,需要进行重金属污染地块风险评估工作,明确污染地块中存在的污染物及对人体健康的影响。以某污染地块为例,通过对地块的受污染情况进行分析,同时对淋洗技术、水泥窑协同处置技术、固化/稳定化技术等污染土壤的修复技术进行对比,最终选择适合的土壤修复技术,经修复后该块重金属污染地块污染风险得到了有效控制,有效减小了污染土壤对人体健康的影响。

Heavy metals will pollute the surrounding soil and groundwater,and then threaten human health.For this reason,it is necessary to carry out risk assessment on heavy metal contaminated land plots to clarify the pollutants existing in the contaminated land plots and their impact on human health.Taking a polluted plot as an example,through analyzing the pollution situation of the plot,and comparing the remediation technologies of contaminated soil such as leaching technology,cement kiln collaborative disposal technology,solidification/stabilization technology,the appropriate soil remediation technology was finally selected.After remediation,the pollution risk of the heavy metal contaminated plot was effectively controlled,and the impact of contaminated soil on human health was effectively reduced.
