[0002] Silicon and fluorine are common pollutants in industrial wastewater. Their presence not only affects water quality, but also can cause long-term harm to the environment and ecosystems. Therefore, it is particularly important to develop effective purification technology.

[0003] However, in the existing industrial wastewater treatment, due to the presence of a large amount of silicon and fluorine-containing substances in wastewater, the poor uniformity of the addition of ferric sulfate-modified activated alumina as a common defluorination agent becomes a key factor affecting the precipitation efficiency. Specifically, if the addition of ferric sulfate-modified activated alumina is not uniform, it will result in the inability of fluorine ions in wastewater to fully contact and react with it, thereby reducing the precipitation efficiency. This not only increases the difficulty and cost of wastewater treatment, but also may affect the effluent quality, making it unable to meet the discharge standard.

[0004] Therefore, in view of the above problem that the poor uniformity of the addition of ferric sulfate-modified activated alumina for purifying wastewater containing a large amount of silicon and fluorine-containing substances results in low precipitation efficiency in the existing industrial wastewater treatment, a removal device for silicon and fluorine in industrial wastewater can be designed.
