Abstract

본 발명은 소석회를 이용하여 불소함유 폐수중의 용존불소이온 제거시 소석회 투입후의 pH를 9이하로 하므로써 불소제거 효율을 향상시키고 슬러지 발생량을 줄이는 것에 관한 것으로, 불소함유 폐수를 처리함에 있어서 소석회 투입후의 pH를 9이하, 바람직하게는 5~9가 되게 하여 처리함을 특징으로 하는 폐수처리 방법에 관한 기술이다.The present invention relates to improving the efficiency of fluorine removal and reducing the amount of sludge generated by treating the fluorine-containing wastewater by removing the fluorine ion from the fluorine-containing wastewater by using the slaked lime to a pH of 9 or less. It is a technique concerning the wastewater treatment method characterized by treating by adjusting pH to 9 or less, Preferably it is 5-9.
