  • 摘要: 采用电絮凝法处理Cu-EDTA模拟废水，研究电极组合方式、初始pH值和氯化钠浓度3个因素对化学需氧量（COD）和Cu去除效果的影响。实验研究发现，当电极组合方式为2个铝阳极和2个铁阴极，起始pH值为3，氯化钠浓度为0.5 g/L，换极周期为40 min，反应时间为80 min时，COD去除率达到78.7%，Cu离子去除率达到99.9%。通过实验研究确定EDTA的去除机制主要是：酸性条件下的次氯酸氧化作用，碱性条件下的氢氧化物絮凝沉淀作用及单核态铝/铁与多核态铝/铁电荷中和作用，Cu的去除机制主要是氢氧化物的絮凝沉淀作用和铁电极的电沉积作用。
    Abstract: In this paper, the electrocoagulation method was investigated for the removal of Cu-EDTA from simulated wastewater. Several operating parameters, namely electrode arrangement, initial pH and NaCl concentration, were studied systematically. It was found that 78.7% rejection of COD and 99.9% rejection of Cu were obtained under the condition of 2 anodes of Al and 2 cathodes of Fe, initial pH 3 and NaCl 0.75 g/L. The polarities of electrodes were switched every 40 min. The reaction time was 80 min. The study suggested that the major EDTA removal mechanism was oxidation by hypochlorite in acidic condition; while under alkaline condition, co-precipitation with Al/Fe oxyhydroxides and charge neutralization by monomeric and polymeric Al species were the main mechanisms. Co-precipitation with Al/Fe oxyhydroxides and electrodeposition by Fe electrodes were the major removal mechanisms of Cu.
