Abstract

The invention relates to a three-dimensional electrolysis sewage treatment method, which comprises the following steps: S1, mixing sewage with a particle electrode, and adsorbing pollutants in the sewage on the particle electrode to obtain an adsorbed mixed solution; S2, dissolving oxygen into the adsorbed mixed solution, introducing the mixed solution with dissolved oxygen into a three-dimensional electrolytic cell, and performing three-dimensional electrolysis on the sewage by using a three-dimensional electrolysis system formed by the particle electrode and a cathode plate and an anode plate in the three-dimensional electrolytic cell; and S3, carrying out solid-liquid separation on the mixed solution subjected to three-dimensional electrolysis to obtain treated water and a particle electrode, and recycling the particle electrode obtained by separation. According to the method, the number of hydroxyl radicals generated in the three-dimensional electrolysis process can be increased, the utilization rate of the hydroxyl radicals is increased, energy consumption is reduced, and the electrolysis efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a three-dimensional electrolytic sewage treatment method. Background technique [0002] The three-dimensional electrolytic sewage treatment technology has attracted much attention in the treatment of refractory organic wastewater and heavy metal ion-containing sewage due to its advantages such as wide application range, simple operation, good treatment effect, no secondary pollution, and easy automatic regulation. For example, it has remarkable effects in the advanced treatment of municipal sewage, decolorization of industrial sewage and removal of heavy metal ions. However, its low current efficiency and high energy consumption are also problems in the application process of three-dimensional electrolytic sewage treatment technology, which have become problems that the field of electrocatalytic oxidation has been striving to solve in recent years. [0003] The three-di...
