Abstract

The invention discloses a method for treating reactive dyes by combining ice gel adsorption material and non-aqueous electrolysis method. The steps are as follows: preparing ice gel polymers: polymerizing under freezing conditions, and the polymers are ready for use; using the above polymers to treat reactive dyes The solution is subjected to adsorption treatment; the polymer after the adsorption treatment is extruded and dried to remove water; the preparation adopts a stainless steel bar as an anode, and a carbon paste electrode as a cathode to carry out anodic oxidation treatment on the active dye in an organic solvent. Compared with traditional aqueous electrolysis methods, non-aqueous electrolysis has higher electrolysis efficiency.

Description

technical field [0001] The invention relates to the treatment of printing and dyeing wastewater, in particular to a cryogel polymer used for the treatment of printing and dyeing wastewater of reactive dyes, a preparation method thereof and a technique for combining it with a non-aqueous electrolytic treatment method. Background technique [0002] Printing and dyeing wastewater pollutes the environment. The wastewater contains a variety of dye components and has a deep color. It must be treated to meet the discharge requirements. [0003] At present, the treatment technologies for printing and dyeing wastewater of reactive dyes include coagulation method, adsorption method, chemical oxidation method, biological treatment method and electrochemical method. Domestic reactive dye printing and dyeing wastewater treatment methods are mainly flocculation and sedimentation combined with chemical methods. [0004] The traditional electrolysis method can remove dyes well, but it has ...
