Abstract

The invention discloses an internal circulation type electrocatalytic oxidation reactor and a sewage purification treatment method, the internal circulation type electrocatalytic oxidation reactor comprises at least one circulation device, the circulation device comprises a reaction cabin, the reaction cabin comprises an inner reaction chamber surrounded by an inner shell and an outer reaction chamber surrounded by an outer shell, an inner electrode plate is arranged inside the inner reaction chamber, the inner reaction chamber is embedded in the outer reaction chamber, a packing layer is arranged between the inner reaction chamber and the outer reaction chamber; the inner electrode plate and the outer shell are used as a negative pole, and the inner shell is used as a positive pole. A first electrocatalytic reaction zone is formed between the electrified inner electrode plate and the electrified inner shell, and a second electrocatalytic reaction zone is formed between the electrifiedouter shell and the electrified inner shell. By use of the characteristics of effective ring opening and breaking of a three-dimensional electrode and high energy efficiency of a two-dimensional electrode, pollutants are jointly degraded, electrocatalytic efficiency is high; the sewage purification treatment method realizes multiple stages and multiple cycles of outer circulating purification ofsewage in the circulation device to ensure the discharged water is up to standard.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to an internal circulation type electrocatalytic oxidation reactor and a sewage purification treatment method. Background technique [0002] Electrocatalytic oxidation technology is a new type of efficient and clean wastewater treatment technology. Many domestic and foreign scholars have applied it to the treatment of refractory organic wastewater. Electrocatalytic oxidation is the use of metal oxide electrodes with catalytic properties to generate hydroxyl radicals (.OH) or other free radicals and groups with strong oxidizing ability through electrochemical processes to attack organic matter in wastewater solutions, causing them to decompose into carbon dioxide , water and simple organic matter. During the entire electrocatalytic oxidation process, because hydroxyl radicals (.OH) directly react with the organic matter in the wastewater solution, the electrocatalytic oxidation technolog...
