In the printing process, a large amount of ink is used, and ink wastewater is inevitably generated, the main characteristics of this wastewater are small water volume, but the concentration is very high, difficult to biodegrade, and intermittent drainage. Contains contaminants such as SS, CODCR, BOD5, color, oil, etc. According to the relevant provisions of China's new environmental protection law, ink wastewater can only be discharged after treatment to meet the discharge standard.
Demulsifier for printing and dyeing factory wastewater is a chemical agent used to treat emulsified oil and suspended solids in printing and dyeing wastewater. By using demulsifiers, the wastewater treatment effect can be effectively improved, the treatment cost can be reduced, and the water quality in the production process can be guaranteed at the same time. The demulsification speed is fast, the water quality is clear after treatment, and the COD removal rate is high, which is more conducive to subsequent sewage treatmentAfter treatment, the amount of sludge is small, the operation is simple, the treatment process is directly simplified, and the treatment efficiency is improved.
The main mechanism of action of the demulsifier in the wastewater of the printing and dyeing factory is to destroy the emulsified state in the wastewater, so that the emulsified oil and suspended solids are separated from the water. Specifically, the demulsifier can be adsorbed on the surface of the emulsified oil particles, reducing the surface tension of the oil particles, making them easy to aggregate and settle. At the same time, the demulsifier can also destroy the structure of the emulsifier through chemical reactions, making it lose its stability and promote the separation of oil and water.
To sum up, the demulsifier of printing plant wastewater is a powerful tool to effectively solve the problem of color printing wastewater pollution. It can decompose the ink components in the wastewater, remove the emulsifier, so that the wastewater can be effectively purified, and protect the health of the water body and ecosystem. At the same time, the demulsifier of color printing wastewater is environmentally friendly and will not cause any negative impact on the environment. In the future development, we should actively promote and use color printing wastewater demulsifier to contribute to environmental protection.
