With the rapid development of science and technology, the electronics industry plays an increasingly important role in the national economy. However, in the production process of electronic products, a large amount of fluorinated wastewater is generated. Fluoride-containing wastewater not only pollutes the environment, but also harms human health.
The fluorine-containing wastewater in the electronics industry mainly includes fluorine-containing chemicals and cleaning wastewater used in the production process of electronic products. The fluoride ions in these effluents are mainly used in the decomposition of fluorinated chemicals and other fluorinated substances in the production process.
Characteristics of fluorinated wastewater in the electronics industry.
1.High concentrations: Fluoride wastewater in the electronics industry has high concentrations of fluoride ions, typically in the range of hundreds to thousands of milligrams per liter.
2.Large variability: Due to uncertainties in the production process, the concentration of fluoride-containing wastewater varies greatly.
3.Difficult to handle: Due to the chemically stable nature of fluoride ions, it is difficult to remove them by conventional chemical or physical methods. Therefore, the treatment of fluorinated wastewater in the electronics industry requires special technical means.
4.Effects on the environment and human health: Fluoride ions are potentially harmful to the environment and human health. Long-term exposure to high concentrations of fluoride-containing wastewater can lead to fluorosis in humans, manifested by symptoms such as tooth macular and joint pain. At the same time, fluoride-containing wastewater also has toxic effects on organisms and plants in the environment.
Fluoride scavenger is a chemical agent for the treatment of low-concentration fluoride-containing wastewater, which can reduce the content of fluoride ions in wastewater to 0Below 5mg L to ensure that environmental protection standards are met. There are a total of 8 fluoride remover products, and different products can be adapted to different types of wastewater in different industries, so as to achieve the purpose of special water treatment.
The treatment of fluoride-containing wastewater in the electronics industry is of great significance for environmental protection and human health, and how to deal with fluorine-containing wastewater in the electronics industry is also a concern of many enterprises, and the use of fluoride removers can reach the ideal standard.
