Claims (1)
- 암모늄이온, 황산염이온 및 유기물을 함유하는 폐수에 수산화칼슘이나 산화칼슘을 가하여 폐수 중에 존재하는 황산이온을 황산칼슘형태로 침전시키고 그로 인해 폐수 중의 암모늄 이온을 암모니아의 형태로 유리시킨 다음 폐수를 열풍과 접촉시킴으로써 상기 암모니아의 전부와 증기로 존재하는 폐수의 일부를 증류시켜 희수하고 그와 동시에 pH가 약 8.5 이상인 증발 잔류물이 생성된 후 증발잔류물을 연소로에 보내 700°내지 1,000℃의 온도에서 연소시킴을 특징으로 하여 암모늄이온, 황산염이온 및 유기물을 함유하는 폐수를 처리하는 방법.
