Problems solved by technology
There are many researches on the treatment of wastewater by electrocatalytic oxidation at home and abroad, but most of them focus on the research on the influencing factors, such as the influence of electrode material, current density, plate spacing, cell voltage, etc. on the wastewater treatment effect, but few studies can consumption problem
Although the electrocatalytic oxidation method can effectively treat coking wastewater and improve the biodegradability of wastewater, the high energy consumption restricts its application in wastewater treatment.

Description
technical field [0001] The invention relates to the technical field of environmental protection, in particular to an experimental method for dynamic electrocatalytic oxidation of sewage. Background technique [0002] Coking sewage is the wastewater produced in the process of high-temperature dry distillation of coal, gas purification and refining of chemical products. At present, biochemical methods can basically remove organic pollutants such as phenols and ammonia nitrogen in this type of wastewater, but the treated effluent still contains some refractory heterocyclic or polycyclic organic pollutants, which cannot meet the national discharge standards or Enterprise reuse requirements require in-depth processing. [0003] The electrocatalytic oxidation method is a clean treatment method that does not require additional oxidant, no secondary pollution, small footprint, high removal rate, strong selectivity, and can be used for advanced treatment of coking wastewater. T...
