Summarize the process technology used in the treatment of water-based ink wastewater Summary of technology used to process water-based ink wastewater Wastewater is a weak alkaline, high concentration, high chroma, biodegradable industrial wastewater, sewage treatment difficulty Larger. The main pollution in the water-based ink production wastewater is acrylic acid series of water-soluble resin (vehicle), ring-shaped organics with coloring groups (pigment) and large molecular weight alcohol or phenyl dispersant, in which the acrylic resin is wastewater The main component of CODcr, accounting for more than 80%. There are a wide range of pigments, including inorganic pigments, salts, oxides and carbon three categories; organic pigments are azo pigments, phthalocyanine pigments, nitro pigments, lake pigments, pigments, nitroso pigments, miscellaneous Ring paint and many other types. In addition also contains stabilizers, defoamers, blockers, surfactants (polyaluminum chloride), preservatives more than 10 kinds of additives. The ideal flow process of filter PAC producers makes the driving force of biochemical reaction increase, the efficiency is improved, the anaerobic tank is in an alternate state and the aerobic is in an alternating state, the purifying effect is good; the operation effect is stable, the sewage settles in an ideal quiescent state, It takes a short time, high efficiency, good water quality; impact load, the pool has stagnated water treatment, basic aluminum chloride on the sewage dilution, buffer effect, effectively resist the impact of water and organic dirt; the process of each Process can be adjusted according to water quality, water, flexible operation; less processing equipment, simple structure, easy operation and maintenance management. Water-based ink to comply with environmental requirements, the product is non-toxic, non-corrosive, non-irritating odor, non-flammable, non-explosive, safe, easy to transport, and the concentration of high, low dosage, low viscosity, good printability, performance Stability, good adhesion fastness, fast drying, water resistance after drying, good alkali resistance and abrasion resistance; easy to adjust during prepress, post-printing and printing process, printed imprints appear imprinted full, colorful, high gloss, Gorgeous and rich, printed complex patterns can also reach a rich level, to print bright and high-gloss color and so on.
