Abstract

The invention belongs to the field of toxic and refractory wastewater treatment and provides advanced oxidation reactors with two structural forms and toxic and refractory wastewater treatment devices with two structural forms. Each toxic and refractory wastewater treatment device integrates three stages of reactors through coupling. The invention further provides toxic and refractory wastewater treatment methods. According to the methods, persulfate and a micro-grade microelectrolysis material are added to first-stage reactors of the wastewater treatment devices, hydrogen peroxide and persulfate are added to second-stage reactors, the micro-grade microelectrolysis material is added to second-stage reactors, and then a Fenton-like reaction, a Fenton reaction and an activated persulfate oxidization reaction are effectively coupled in the three stages of reactors; with the adoption of the methods, the wastewater treatment effect can be enhanced and improved, and the wastewater treatment cost can be reduced.

Description

technical field

[0001] The invention belongs to the field of toxic and refractory wastewater treatment, and in particular relates to an advanced oxidation reactor, a device for treating toxic and refractory wastewater and a method for treating toxic and refractory wastewater. Background technique

[0002] At present, advanced oxidation technologies such as Fenton-like reaction, Fenton reaction and new activated persulfate oxidation are mainly used for pretreatment or advanced treatment of toxic and refractory wastewater. The Fenton-like reaction refers to the reaction of zero-valent iron or iron-based multimetallic materials under aerobic conditions to convert O 2 reduced to H 2 o 2 , then at Fe 2+ Under the catalysis of catalysis, strong oxidizing hydroxyl radicals (OH) are generated in situ, and the reaction equations are shown in formulas (1)-(2); Fenton reaction refers to H 2 o 2 in Fe 2+ Under the catalytic action of OH, strong oxidizing OH is produced, and the re...
