Abstract
본 발명은 불소가 함유된 폐수를 처리함에 있어서, 폐수의 pH를 중성이하로 조절한 후 가용성 희토류 화합물을 첨가시켜 불소제거 효율을 증대시키는 것에 관한 것으로, 불소함유 폐수를 가용성 희토류 화합물로 처리함에 이어서, 폐수에 무기산을 투입하여 pH를 중성이하로 조절 후 가용성 희토류 화합물을 첨가하여 폐수중의 불소를 제거시키는 것을 특징으로 하는 불소함유 폐수의 처리방법에 관한 기술이다.The present invention relates to increasing the efficiency of fluorine removal by adjusting the pH of wastewater to neutrality and then adding soluble rare earth compounds in treating fluorine-containing wastewater, and then treating fluorine-containing wastewater with soluble rare earth compounds. , A method for treating fluorine-containing wastewater, characterized in that fluorine is removed from the wastewater by adding an inorganic acid to the wastewater to adjust the pH to neutral and then adding a soluble rare earth compound.
