The iron and steel industry is an important pillar industry of China's national economy. With the rapid development of the iron and steel industry, a large amount of wastewater will be generated during the steel production process. Fluoride is one of the common pollutants generated during the steel production process, mainly coming from process links such as steelmaking and steel rolling. Fluoride is toxic to the environment and aquatic organisms. Long-term discharge will lead to soil and water pollution and affect the ecological balance. The problem of wastewater discharge from steel mills has become increasingly prominent and has become one of the important environmental problems.
The fluoride removal agent belongs to a polymer. It can adsorb, electrically neutralize, flocculate, separate and precipitate fluoride ions in water, thus achieving the removal of fluoride. At the same time, it can also remove COD, chromaticity, total phosphorus, SS (suspended solids) and heavy metals in water. It has the advantages of good removal effect, simple operation and low operation cost.
Characteristics of the Fluoride Removal Agent for Steel Mill Wastewater：
1.High efficiency: The fluoride removal agent for steel mill wastewater usually has high-efficiency fluoride removal ability and can quickly remove fluoride in the wastewater to meet the national discharge standards.
2.Selectivity: The fluoride removal agent has selectivity for the removal of fluoride. It can effectively distinguish and remove fluoride ions in the wastewater, with little impact on other ions.
3.Stability: The fluoride removal agent should have good chemical stability during the treatment process, be not easy to decompose, and can maintain its fluoride removal effect for a long time.
4.Safety: The fluoride removal agent should be non-toxic, harmless and environmentally friendly. At the same time, it has no impact on human health and safety during the use process.
5.Economy: The cost of the fluoride removal agent should be relatively low, which is convenient for large-scale industrial applications. At the same time, its service life and regeneration efficiency should be considered.
6.Simple operation: The use process of the fluoride removal agent should be simple and easy to implement, which is convenient for operators to master and reduces the complex operations in the treatment process.
In the application process, the selection of the fluoride removal agent should be determined according to the specific components, concentration, pH value and other factors of the wastewater to ensure the best fluoride removal effect and economic benefits. At the same time, in order to meet the environmental protection requirements, the use of the fluoride removal agent also needs to be combined with other wastewater treatment technologies, such as coagulation sedimentation and biological treatment, to achieve the comprehensive purification of the wastewater.
