Paint wastewater is a major challenge in the treatment of chemical wastewater. There are two sources of paint wastewater: one is the spray paint wastewater generated by furniture, automotive and other production enterprises after the spray paint workshop is saturated with water adsorption, and the other is the production wastewater of paint production enterprises. Paint contains toxic substances that are soluble in water. Once polluted, it can cause significant damage to the ecological environment and pose a great threat to human life. So the treatment of industrial paint wastewater is urgent.
Due to the high-density cationic charge groups unique to paint water treatment decolorizing agents, they can combine with the anionic groups of chromogenic substances in wastewater to form hydrophobic and insoluble salts that can be separated from water. In addition, various active groups on the molecular chain of paint water treatment decolorizing agents can react with anionic groups such as sulfonic and carboxylic groups in dye molecules to form insoluble substances that can be removed from water, thereby removing the color from water,
Use paint water to treat decolorizing agents to reduce environmental pollution and achieve legal discharge of wastewater.
