Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly relates to a wastewater treatment and recycling device for the production of water-based ink. Background Art

[0002] Water-based ink is an ink with water as the main solvent, and its components include water, resin, pigment and additives. During the printing process, the water-based ink achieves the drying of printed matter through the evaporation of water and the curing of resin. Water-based ink does not contain harmful solvents and is harmless to the environment and human health. During the printing process, no toxic and harmful gases will volatilize, greatly reducing the degree of environmental pollution in the printing industry.
