【摘要】：利用外加电场强化铁炭修复地下水中的苯和二甲苯污染,根据试验结果确定最佳条件:修复苯和二甲苯污染地下水的零价铁与活性炭的最佳比例分别为1∶1.5、1∶1,修复的最佳pH值分别为5.5、4.5,外加电场强化零价铁与活性炭联合修复苯和二甲苯的适宜电压分别为18、27 V,可使苯和二甲苯的去除率分别达到78.63%和94.17%。外加电场强化铁炭混合修复苯和二甲苯污染地下水可以使去除率比单独铁炭混合提高28%~34%。
[Abstract]:Remediation of benzene and xylene pollution in groundwater by applying applied electric field to iron and carbon, According to the test results, the optimum conditions were determined: the optimum ratio of zero-valent iron to activated carbon for remediation of benzene and xylene contaminated groundwater was 1: 1.5 / 1, respectively, and the best pH value for remediation was 5.5 ~ 4.5, respectively. The applied electric field strengthened zero-valent iron and activated carbon. The optimum voltage for the combined remediation of benzene and xylene is 1827 V, and the removal rates of benzene and xylene can reach 78.63% and 94.17.7% respectively. The combined remediation of benzene and xylene can increase the removal rate by 28% compared with that of iron and carbon mixture alone.
