Abstract
본 발명은 알루미늄 슬러지 재순환방법에 의한 불소처리방법으로 농축된 불소이온의 제거를 위해 기존의 소석회 대신 염화칼슘의 철염을 사용하므로써 반응시간을 단축시키고 양이 많은 알루미늄 슬러지의 발생을 칼슘 슬러지로 바꾸므로써 슬러지 발생량을 감소시키는 불소함유 폐수 처리방법.

Claims (2)
- 불소가 다량 함유된 폐수의 처리방법에 있어서, 불소이온 제거시 사용된 알루미늄 슬러지를 pH 12이상으로 1회 조정하여 염화칼슘, 황산철 및 염화철같은 철화합물 또는 염화칼슘을 사용하여 불소이온을 고형 침전물로 제거하고 여액을 재사용하는 것을 특징으로 하는 알루미늄 슬러지를 사용한 불소폐수 처리방법.
- 제1항에 있어서, 공정 중 소모된 알루미늄 화합물의 양만큼을 보충하는 것을 특징으로 하는 알루미늄 슬러지를 이용한 불소폐수 처리방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
