在以铝为极板的电絮凝中加入过氧化单硫酸钾盐（KHSO₅，PMS），形成Al-Al EC/PMS系统，用以处理云南某露天煤矿含锰、锌及铁的矿坑废水，并与传统的以铁为极板的电絮凝系统（Fe-Fe EC/Na₂SO₄）相比较，从剩余金属离子浓度以及反应结束后絮体状态等方面探讨不同系统的处理效果。结果表明，Al-Al EC/PMS系统处理效果更优，加入20 mmol/L的NaCl作为支持电解质，电流密度为10 mA/cm²，添加6 mmol/L的PMS反应45 min即可使废水中的总锌、总锰浓度达到《城镇污水处理站污染物排放标准》（GB 18918—2002）一级A的排放标准。通过XPS分析了系统处理后形成的金属化合物为MnO₂、Zn （OH）₂、FeO和Fe₂O₃等。

Al-Al EC/PMS system is formed by adding potassium peroxymonosulfate (PMS) in the electroflocculation with aluminum as the plate electrode,and used to remove manganese and zinc-containing wastewater from an open-pit coal mine in Yunnan province of China.It is compared with the electro-flocculation system (Fe-Fe EC/Na₂SO₄) with iron as the plate electrode,and their treatment effects are discussed in terms of the concentration of remaining metal ions and the state of the flocs after the reaction.The results show that the treatment effect by Al-Al EC/PMS system is better than that by Fe-Fe EC/Na₂SO₄ system.If adding 20 mmol·L^-1 NaCl as supporting electrolyte,the current density is 10 mA·cm^-2.If 6 mmol·L^-1 PMS is added,the concentration of total zinc and total manganese in wastewater can reach the emission standard for Class A of "Emission Standard for Pollutants from Urban Sewage Treatment Stations"(GB 18918—2002) in 45 minutes.It is verified by X-ray photoelectron spectroscopy (XPS) that the corresponding metal compounds formed after treatment include MnO₂,Zn(OH)₂,FeO and Fe₂O₃.
