【摘要】：利用外加電場強(qiáng)化鐵炭修復(fù)地下水中的苯和二甲苯污染,根據(jù)試驗結(jié)果確定最佳條件:修復(fù)苯和二甲苯污染地下水的零價鐵與活性炭的最佳比例分別為1∶1.5、1∶1,修復(fù)的最佳pH值分別為5.5、4.5,外加電場強(qiáng)化零價鐵與活性炭聯(lián)合修復(fù)苯和二甲苯的適宜電壓分別為18、27 V,可使苯和二甲苯的去除率分別達(dá)到78.63%和94.17%。外加電場強(qiáng)化鐵炭混合修復(fù)苯和二甲苯污染地下水可以使去除率比單獨鐵炭混合提高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.
