1、 Source of ink wastewater
Ink is mainly used in low-end printed materials such as books and magazines, printing industries with low requirements such as corrugated paper, flexible printing fields such as cigarette factories, distilleries, pharmaceutical factories, cosmetics, children's toy enterprise product packaging, milk and beverage composite paper packaging, and other cardboard packaging industries. During the production and application of water-based ink, a certain amount of water-based ink wastewater is generated due to equipment cleaning. The main source of wastewater in the application field of water-based ink is the drainage of printing related equipment that needs to be cleaned, such as washing sticks, washing tanks, washing buckets, and washing operation rooms, when replacing ink.
2、 Characteristics of water-based ink
Ink wastewater is a new type of typical wastewater, characterized by high CODcr, high difficulty, high chromaticity, and difficult biodegradation, making it difficult to treat. Once it enters the water body, it will cause great pollution to the water environment, seriously threatening human production and life as well as the ecological balance of the natural world.
3、 Introduction to sewage treatment process
Our company has developed a new wastewater treatment process based on the characteristics of water-based inks in the printing industry and our years of engineering practice experience. This process enables the complete reuse of all wastewater, achieving zero discharge.
4、 Characteristics of sewage treatment
1. Low investment, advanced technology, and small footprint.
2. The treatment effect is good, and the emission indicators after treatment fully meet the highest national emission standards
3. The treated water quality meets the reuse standard and truly achieves zero emissions.
