Laboratory scale batch EC experiments were performed on real metallurgical industry wastewater (MIWW). The most suitable process conditions were found to be: Al anode, a current of 1.05 A (150 A/m²) and a treatment time of 5 min (175 C/L). Operating costs and electrical energy consumption values were very low, 0.065 €/m³ and 0.44 kWh/m³, respectively. In the most suitable process conditions, 96% of turbidity, 92% of TSS, 87% of Al_tot, 99.9% of Cr, 99.6% of Zn, and 96% of COD could be removed from MIWW. Filtration tests showed that filter size had a significant effect on the residual metal content, and less than 10% of the Al, was in a dissolved form. Similar results were obtained for both Fe and Al anodes. Test runs with a novel pilot-scale continuous EC system were also conducted. These results were well in line with the batch experiments. To obtain the best possible results in the treatment of MIWW, the continuous EC treatment system needs to be followed by a settling or filtration step. The results obtained in this work were repeatable. To conclude, EC was shown to be a feasible technology for the treatment of real MIWW.

实验室规模的批量EC实验是在真正的冶金工业废水（MIWW）上进行的。发现最合适的工艺条件为：Al阳极，1.05 A（150 A / m ²）的电流和5 min（175 C / L）的处理时间。运营成本和电能消耗值非常低，分别为0.065€/ m ³和0.44 kWh / m ³。在最合适的工艺条件下，浊度为96％，TSS为92％，Al _tot为87％MIWW可以去除99.9％的Cr，99.6％的Zn和96％的COD。过滤测试表明，过滤器的尺寸对残余金属含量有显着影响，并且少于10％的Al处于溶解状态。Fe和Al阳极均获得了相似的结果。还使用新型中试规模的连续EC系统进行了测试。这些结果与批处理实验非常吻合。为了在MIWW的治疗中获得最好的结果，需要在连续的EC处理系统之后进行沉降或过滤步骤。在这项工作中获得的结果是可重复的。总而言之，EC被证明是治疗实际MIWW的可行技术。
