A combined technology between Iron-carbon micro-electrolysis (ICME) and H₂O₂ using scrap iron and granular active carbon was extensively investigated and optimized (three main independent parameters chosen) for chemical oxygen demand (COD) removal of landfill leachate reverse osmosis (RO) concentration by batch experiments. A regression quadratic equation was developed to model the outcome using central composite design (CCD) coupled with response surface methodology. A global optimization method–the convex optimization was applied to determine the optimal parameters. Under optimal parameters determined as C/Fe (Surface area) of 717143.8, H₂O₂ concentration of 1687.6 mg/L and pH of 3.8, the corresponding COD removal efficiency was up to 86.9%. Consequently, the COD in the effluent was less than 300 mg/L. The treated water can meet the level B standards of Wastewater Quality Standards for Discharge to Municipal Sewers (CJ 343—2010).

广泛研究和优化了铁碳微电解（ICME）和H ₂ O _2结合废铁和颗粒状活性炭的结合技术，并进行了优化（选择了三个主要独立参数），用于垃圾渗滤液反渗透的化学需氧量（COD）去除（RO）通过分批实验浓缩。开发了回归二次方程式，以使用中央复合设计（CCD）结合响应面方法对结果进行建模。全局优化方法–凸优化用于确定最佳参数。在确定为717143.8的C / Fe（表面积）的最佳参数下，H ₂ O ₂浓度为1687.6 mg / L，pH值为3.8，相应的COD去除率高达86.9％。因此，废水中的COD低于300 mg / L。处理后的水可以达到《城市污水排放质量标准》（CJ 343—2010）的B级标准。
