Commissioning and Operation of Fluidized Bed Process for Advanced Treatment of Fluoride-Containing Refrigerant Wastewater
Since the excessive accumulation of fluoride in the environment will pose a serious threat to the environment and human health,the advanced treatment of fluoride-containing wastewater has increasingly become a hot issue of concern in the field of water treatment in recent years.For the mixed wastewater generated in the refrigerant production process of a fluorine chemical enterprise,the fluidized bed process was applied to carry out the advanced treatment of refrigerant fluoride-containing wastewater,and the commissioning of the fluidized bed operation in the process was summarized.Results of commissioning operation showed that the best fluoride removal effect was achieved at the fluidized bed stirring speed of 1 r/min and pH value of 6.5,and the F-was reduced from 30.47 mg/L to 7.77 mg/L.The fluidized bed chemical dosage was controlled at 1600 mg/L,which was more economical.Through the commissioning operation,the treatment load of the equipment reached 4 m3/h and the system was operated stably.After the commissioning of the process was completed,the effect had been stable and efficient since its operation.Compared with the traditional fluoride adsorption process,it could significantly reduce the operating cost.The commissioning results showed that the fluidized bed advanced defluoridation process could achieve efficient and economic treatment of fluoride-containing wastewater and provided ideas and experience for fluoride-containing wastewater treatment projects.
