  • 摘要: 为了同时去除地下水中的氟和砷，提出了Al/C/Fe复合电极电絮凝法和Al/C-Fe/ C依次除氟砷法，并进行效果对比。研究了Al/C/Fe复合电极电絮凝法的影响因素，并对复合电极电絮凝产生的絮体进行了SEM-EDX分析。结果表明，Al/C/Fe复合电极电絮凝法对氟、砷的去除速率分别是Al/C-Fe/C依次除氟砷法的1.43倍和4.73倍；初始氟/砷浓度为4.0/1.0、4.0/0和0/1.0 mg/L 3种条件下，通过铝极板、铁极板的电流密度均为0.10 mA/cm2时，达到最好的除氟除砷效果，与初始氟/砷浓度无关。
    Abstract: In order to remove F- and As(Ⅴ)ions from groundwater simultaneously, a system of Al/C/Fe combination electro-coagulation and a system of Al/C-Fe/C used in sequence were designed. Influencing factors of Al/C/Fe combination electro-coagulation were researched, and flocs produced in the combination electro-coagulation were analyzed by SEM-EDX. The results showed that the Al/C/Fe combination system's removal rates of F- and As(Ⅴ) ions are 1.43 times and 4.73 times of that of the system of Al/C-Fe/C used in sequence. When the current density of Al and Fe electrode is 0.10 mA/cm2, the removal of F- and As(Ⅴ)ions is the best when the initial F/As(Ⅴ) concentrations are 4.0/1.0 mg/L,4.0/0 mg/L and 0/1.0 mg/L, so the best value of current density has no dependence on the initial F/As(Ⅴ) concentration.
