Taking a way of continuous flow, ordinary fluidized bed continuous flow approach measured the amount of fluoride crystals and the treatment effect. Using intermittent operation, bubbling fluidized bed measured the amount of fluoride crystal and the treatment effect. The results show that: ordinary fluidized bed treatment effect worse than the bubbling fluidized bed. Bubbling fluidized bed in a short time large amount of fluoride crystals, can be a lot of fluoride to fluoride content of waste water treatment 10mg / L or less. The technical processing speed, good effect, the reaction vessel is small, simple device, easy to control, with good prospects for practical application.
