摘　　要：某遗留有机污染场地采用原位化学还原技术进行修复,注射影响半径取3 m,在修复区域中心及其四个垂直轴向上3 m范围内共布设5个修复点位,工程地块内共布设10个修复点位,分5次注射芬顿试剂。监测井采样数据显示,原位化学还原技术对苯、氯苯及石油烃(C_(10)~C_(40))的降解效果显著,注射前期和中期储罐区苯向北侧区域迁移,后期迁移不明显。A residual organic pollution site is restored by using in-situ chemical reduction technology,the injection influence radius is taken as 3 m,and a total of 5 remediation points are arranged in the center of the repair area and within 3 m of its four vertical axes,and a total of 10 remediation points are set up within the project site,and Fenton reagent is injected 5 times.The monitoring well sampling data shows that the in-situ chemical reduction technology has significant degradation effects on benzene,chlorobenzene,and petroleum hydrocarbons(C_(10)~C_(40)),in the early and middle stages of injection,benzene in the storage tank area migrates to the north side area,but the migration is not significant in the later stage.
