有机物与重金属复合污染土壤联合修复技术工程应用实例

以上海某地块有机物与重金属复合污染土壤修复工程为实例,根据土壤污染状况初步调查、详细调查和风险评估,确定了该地块的污染状况、修复目标和修复范围。修复施工前,通过小试试验和中试试验确定修复药剂的种类和用量。修复施工结束后,对项目的修复效果进行评价,认为修复后的土壤环境质量达到了修复目标。该项目的成功实施可为其他类似污染地块的土壤修复项目提供借鉴。

The engineering example is a soil remediation project for organic and heavy metal compound pollution in a certain plot of land in Shanghai.Based on preliminary investigation,detailed investigation,and risk assessment of soil pollution,the pollution status,remediation goals,and remediation scope of the plot have been determined.Before repair construction,determine the type and dosage of repair agents through small-scale and pilot tests.After the restoration construction is completed,the restoration effect of the project is evaluated,and it is believed that the soil environmental quality after restoration has reached the restoration goal.The successful implementation of this project can provide reference for soil remediation projects in other similar polluted plots.
