A method for defluoridation of fluoride-containing wastewater

PendingCN122301344ASuspended particlesSludge
This application relates to the field of water treatment technology and discloses a method for defluoridating fluoride-containing wastewater. The method includes introducing fluoride-containing wastewater from the bottom into a crystalline granulation fluidized bed filled with natural garnet seed crystals, thus fluidizing the seed crystals. Simultaneously, calcium chloride solution and sodium hydroxide solution are pumped in from the side and below to adjust the Ca / F molar ratio and pH value of the reaction system, promoting an induced crystallization reaction between fluoride ions and calcium ions in the aqueous phase on the surface of the garnet seed crystals to precipitate calcium fluoride. After the reaction stabilizes, the treated water is discharged from the top of the bed to obtain defluorinated effluent. This method addresses the homogeneous nucleation phenomenon in the aqueous phase caused by high influent fluoride concentration shocks, and combines this with subsequent coagulation and sedimentation processes to remove suspended particles. This application overcomes the shortcomings of traditional sedimentation methods, which easily generate loose flocs, achieving a stable transfer of fluoride to a dense solid phase, effectively reducing the production of water-containing sludge, and ensuring the quality of the effluent from the defluoridation system under high load fluctuations.
