摘　　要：地下水受到苯与甲苯等苯系物污染,会对人体健康造成巨大伤害。本试验利用芬顿试剂氧化处理苯和甲苯污染地下水,首先分析氧化还原电位(ORP)和pH随反应时间的变化,然后分别改变H_(2)O_(2)与苯系物、Fe^(2+)的摩尔比,研究其对修复效果的影响。试验结果表明,H_(2)O_(2)与苯系物的摩尔比为10∶1,H_(2)O_(2)与Fe^(2+)的摩尔比为2∶1时,苯和甲苯污染地下水修复效果最佳。芬顿试剂对苯和甲苯污染地下水有较好的修复效果,未来可以应用在实际污染场地地下水修复中。Groundwater is polluted by benzene derivatives such as benzene and toluene,which can cause significant harm to human health.This experiment uses Fenton reagent to oxidize groundwater contaminated with benzene and toluene,firstly analyzes the changes in oxidation-reduction potential(ORP)and pH with reaction time,and then changes the molar ratios of H_(2)O_(2)to benzene derivatives and Fe^(2+)respectively to study their impact on the remediation effect.The experimental results show that when the molar ratio of H_(2)O_(2)to benzene derivatives is 10∶1,and the molar ratio of H_(2)O_(2)to Fe^(2+)is 2∶1,the remediation effect of benzene and toluene contaminated groundwater is the best.Fenton reagent has a good remediation effect on groundwater contaminated with benzene and toluene,and can be applied in actual remediation of groundwater in contaminated sites in the future.
