含氟废水处理方法研究进展OA

The sources and hazards of fluorine-containing wastewater are reviewed.The principles and application bottlenecks of traditional defluorination technologies are outlined,including the chemical precipitation method,the coagulation-precipitation process,the ion exchange method,the membrane separation process,and the adsorption method.The mechanisms and advantages of emerging technologies are particularly analyzed,such as electrodeionization technology,fluidized bed crystallization,and membrane capacitance-based deionization technology.Treatment methods for organic fluorine pollutants are discussed,including per-and polyfluoroalkyl substances(PFAS).It is pointed out that future research should focus on the development of functional materials and integrated process optimization to overcome current technical limitations.A"treatment-recovery-utilization"industrial chain and high-value markets should also be constructed to advance the treatment of fluorine-containing wastewater toward high efficiency,eco-friendliness,and resource utilization.
