Fluorine-containing industrial wastewater treatment system and treatment method thereof

The invention provides a fluorine-containing industrial wastewater treatment system and a treatment method thereof. The method comprises the steps of pH adjustment, primary fluorine removal, secondary fluorine removal, precipitation clarification, resin fluorine removal and sludge treatment. According to the defluorination treatment method, the treated high-concentration fluorine-containing wastewater is stable in effluent and can reach the discharge standard of less than 10mg/L, and the treated wastewater can be recycled and also can be directly discharged. 本发明提供了一种含氟工业废水处理系统及其处理方法，该方法包括：调节pH、一次除氟、二次除氟、沉淀澄清、树脂除氟和污泥处理。本发明所述的除氟处理方法，能够让高浓度含氟废水经过处理后出水稳定且能够达到小于10mg/L的排放标准，处理后的废水可以回用，也可以直接排放。
