NOVELTY - Method for electrochemical oxidative degradation of sewage chemical oxygen demand involves mixing 1 L to-be-processed sewage with 1 g boron reagent, pumping resultant water to an electrolytic cell equipped with boron-graphene electrode, electrolyzing for 3 hours, filtering and recovering residue. USE - Method for electrochemical oxidative degradation of sewage chemical oxygen demand (claimed). ADVANTAGE - The method enables electrochemical oxidative degradation of sewage chemical oxygen demand by effectively recovering and recycling the boron reagent.
