Hardware grinding wastewater refers to the wastewater containing metal particles, oil stains and solid suspended solids generated in the process of hardware processing. This wastewater treatment is essential for environmental protection and resources**. However, there is often emulsification in hardware grinding wastewater, that is, oil and wastewater form an emulsion suspension, which brings great difficulties to the treatment of wastewater. In order to solve this problem, the demulsifier of hardware grinding wastewater came into being.
Hardware grinding wastewater demulsifier mainly achieves the demulsification effect through two mechanisms. One is the surfactant mechanism, the surfactant in the demulsifier can interact with the oil in the wastewater and destroy its emulsified state. By changing the properties of the oil-water interface, the oil stain is separated, so as to achieve the effect of demulsification. The other is the chemical precipitation mechanism, the precipitant in the demulsifier can react with the solid particles in the wastewater to form a complex that is easy to precipitate, promote the formation of precipitation, and thus separate oil pollution and solid suspended solids.
There are some operational requirements that need to be paid attention to when using metal grinding wastewater demulsifier to ensure demulsification effect and work safety. First of all, the appropriate demulsifier should be selected according to the nature and emulsification degree of the wastewater, and the dosage should be controlled. Dosing too low may not achieve the desired demulsification effect, while too high dosing can lead to waste and additional environmental concerns. Secondly, according to the characteristics and treatment requirements of the wastewater, the appropriate demulsifier mechanism and treatment process should be selected to achieve the best demulsification effect. Finally, the treated wastewater and the residues of the demulsifier used should be properly treated to avoid secondary pollution.
Demulsifier for hardware grinding wastewater plays an important role in solving the problem of hardware grinding wastewater. It can improve the oil-water separation effect of wastewater, improve the treatment efficiency and water quality of wastewater. Through the application of demulsifier, it can effectively reduce the content of oil and solid suspended solids in wastewater, reduce the pollution degree of wastewater, protect the environment and water resources, and promote the development of green chemical industry.
