Description

Wastewater treatment device and treatment method thereof

Technical Field

The invention relates to the field of resin production wastewater treatment devices, in particular to a wastewater treatment device and a treatment method thereof.

Background

The ink resin is a carrier of the pigment in the ink, is a core material of the ink, and the quality of the ink resin directly influences the performance of the ink, because the binder determines the viscosity, the drying property, the fluidity and other properties of the ink to a great extent.

The adhesion force generated between the ink and the printing stock mainly comprises chemical bond force (i.e. interatomic force), intermolecular force (hydrogen bond force and Vanderwaals force), interface electrostatic attraction force and mechanical force. The primary source of these forces is the interaction between the resin binder for the ink and the substrate. The selection of proper resin connecting materials is also critical for different base materials, generally speaking, for nonpolar base materials such as PE, PP and the like, the surface tension can only reach about 38 dynes even if the corona surface treatment is carried out, and the resin connecting materials such as chlorinated polypropylene resin connecting materials with nonpolar resin structures are adopted; for the surface polar substrate such as PET and PA, a polyurethane resin binder can be used. The polyurethane ink binder system can solve the problem of adhesion on a nonpolar base material by adding a small amount of adhesion promoters specially used for PP and PE or combining a small amount of chlorinated polypropylene resin with polyurethane resin, and can achieve the problem of universality of a resin binder.

Although the resin is at the adhesion force problem of the printing ink on nonpolar substrate that solves to a certain extent, this also causes the stickness of printing ink too big, in the in-process of resin printing ink production, it bonds on positions such as storage jar and conveyer pipe very easily to cause the printing ink, influence going on of production, need shut down the clearance, and in the in-process of clearance produce a large amount of waste water that is rich in organic matter very easily, need handle the back and just can discharge in nature, current processing method roughly can divide into the preliminary sedimentation, utilize the flocculating agent to precipitate, utilize activated sludge to carry out final processing to remaining organic matter in the sewage at last, wherein, it is comparatively slow to utilize the flocculating agent to carry out the processing procedure, though utilize the stirring machine to stir can effectively promote reaction rate, but the promotion effect is limited.
