摘　　要：针对某工业场地土壤被多种有机物污染问题,采用化学氧化修复技术修复,试验研究表明,针对土壤中苯并(a)芘、乙苯、2-氯甲苯、4-氯甲苯污染物修复,药剂用量过硫酸盐5%、精石灰1%,作用时间5d时修复效果最佳,可以将污染土壤中多种有机物浓度降到修复目标值以下。In view of the problem that the soil of an industrial site is polluted by various organic substances,the chemical oxidation remediation technology is used for remediation.The experimental study shows that for remediation of benzo(a)pyrene,ethylbenzene,2-chlorotoluene,4-chlorotoluene pollutants in the soil,the best remediation effect is when the dosage of the agent is 5%persulfate,1%refined lime,and the action time is 5 days,which can reduce the concentration of various organic substances in the contaminated soil to below the remediation target value.
