Abstract

The invention relates to the field of environmental pollution control, in particular to an electrocatalytic activity regulation method based on inert ion intercalation. The present invention comprises the steps of processing an electrochemical electrode material with a defect state structure, and then passing Na + 、K + , Ca 2+ , Mg 2+ Such inert metal ions form a highly concentrated ion atmosphere on the electrode surface, and the ions are inserted into the electrode defect state layer through the strong interaction between the electrode and the ion atmosphere. The present invention uses common cations in traditional sewage as the means of electrode regulation, and has outstanding treatment effects when controlling high-salt organic wastewater; in addition, this method saves the process of coprecipitation, doping and roasting that is often used in traditional electrode regulation and activity, and has the advantages of Outstanding economic value and industrial benefits.

Description

technical field

[0001] The invention relates to the field of environmental pollution control, in particular to an electrocatalytic activity regulation method based on inert ion intercalation. Background technique

[0002] Electrochemical method is a common advanced oxidation technology for treating organic pollutants in wastewater. This method is a research hotspot in the treatment of high-concentration organic wastewater and secondary biochemical effluent. The basic mechanism of electrochemical treatment of wastewater is to generate strong oxidizing substances (OH, H 2 o 2 、 O 2 etc.), with direct oxidation and indirect oxidation reactions with organic pollutants in sewage and wastewater, decomposing high-concentration, difficult-to-biodegrade macromolecular organic matter into easily biodegradable small-molecular organic matter, and even completely mineralizing it into CO 2 and H 2 O and other inorganic substances.

[0003] Electrochemical devices are all electrolyti...
