摘　　要：由于氟化物在环境中的过量积累会对环境及人体健康造成严重威胁,近年来,含氟废水的深度处理日益成为水处理领域关注的热点问题。针对某氟化工企业制冷剂生产过程中产生的混合废水,应用流化床工艺,进行了制冷剂含氟废水的深度处理,并对工艺中流化床运行调试进行了总结。调试运行结果表明,流化床搅拌转速为1 r/min,pH值为6.5时除氟效果最好,实现F~-质量浓度自30.47 mg/L降低至7.77 mg/L,流化床药剂投加量控制在1600 mg/L较为经济。通过调试运行使设备处理负荷稳定达到4 m~3/h,实现系统稳定运行。该工艺调试完成后,运行至今一直稳定高效。与传统除氟剂吸附工艺相比,能够显著降低运行成本。调试运行结果表明,流化床深度除氟工艺可实现含氟废水高效、经济处理,为含氟废水处理工程提供思路与经验。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.
