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.
