Description
technical field [0001] The invention belongs to the technical field of wastewater purification, in particular to a printing ink wastewater treatment and purification device. Background technique [0002] During the printing process, due to the cleaning of the equipment, a certain amount of ink waste water will be generated. The ever-changing color of water-based ink causes the chemical composition of its wastewater to be quite complex, with the characteristics of high COD, high chroma, and refractory biodegradation. Once it enters the water body, it will cause serious pollution to the water environment. The main pollution components in ink wastewater are cyclic organic matter (colorant) containing colored groups, water-soluble resin (vehicle) of acrylic acid series, large molecular weight alcohol group or phenyl dispersant, in these types of pollution The water-soluble resin in the waste water is the main component of the wastewater CODcr, accounting for more than four-fift...
