Claims (1)

  1. 불소(F)의 각종 중금속이 함유된 폐수에 Ca(OH)2와 KI를 일정비율로 혼합한 알칼리제를 투입하여 pH를 11.0-11.5로 조절하여 불소 및 중금속을 침전시키는 단계; 일정량의 폴리머(Polymer)를 응결제로서 투입하여 침전물 입자를 조대화시켜 다시 침전시키는 단계; 연화제로서 NaHCO3를 투입하여 Ca+2를 침전시키는 단계; 여과처리하여 침전물을 제거시키는 단계; 및 여과처리에 의해 침전물이 제거된 여과수에 묽은 황산을 첨가하여 pH를 5.8-8.6으로 중화시키는 단계를 포함하여 구성되는 것을 특징으로 하는 불소 및 중금속 함유 폐수처리방법.
