摘　　要：安徽某退役化工厂约428m~2地块的地下水受到了苯污染,选用原位化学氧化-高压旋喷方式进行修复,地下水污染物浓度可达到修复目标。工程实施结果表明,过氧化氢对低浓度苯污染地下水具有一定的修复效果,结合高压旋喷技术可确保药剂扩散效果且能有效避免二次污染。In a decommissioned chemical plant in Anhui Province,the groundwater within a plot of about 428m2 was polluted by benzene.The method of in-situ chemical oxidation+high-pressure jet grouting injection was used for remediation,and then the concentration of pollutants in groundwater could reach the remediation targets.The results of the project show that hydrogen peroxide has a certain remediation effect on the groundwater contaminated by low-concentration benzene,and the combined application of high-pressure jet grouting technology can ensure the diffusion effect of the agent and effectively avoid secondary pollution.
