Abstract

The invention discloses a coagulant for water-based ink wastewater and a water-based ink wastewater treatment method, and belongs to the technical field of wastewater treatment. The coagulant for thewater-based ink wastewater comprises dilute sulfuric acid, polyaluminum chloride, activated carbon and vermiculite powder. According to a water-based ink wastewater treatment method, the coagulant isadopted for flocculent precipitation of the wastewater. The treatment method disclosed by the invention is rapid and simple, is a combined treatment technology, requires light and simple equipment, can be freely combined and moved, is particularly suitable for enterprises or units which intermittently produce sewage and produce less sewage at a time, and can be used for timely treatment after production.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a coagulant for water-based ink waste water and a treatment method for water-based ink waste water. Background technique [0002] Water-based ink is a printing material in the form of a solution or emulsion that uses water as a solvent, water-soluble polymer materials as a linking agent, and then adds pigments and additives. Because it uses water as a solvent and contains only a small amount (or no) of organic solvents, it has the advantages of non-combustibility, safe transportation and storage, extremely low VOC emissions during production and use, and no harm (or minimal harm) to operators. It is a new type of green printing material, which is widely used in the printing of books, newspapers, magazines, packaging materials, advertising decoration materials, paper for architectural decoration, paper-plastic composite, and some rubber-plastic materials. During the...
