Claims (6)

  1. a) 공지량의 고분자전해질 처리제를 수 처리 공정으로 처리되는 오염 물질을 포함하는 물에 부가하는 단계; b) 공정에 또한 부가되는 공지량의 고분자전해질을 기준으로 하여 고분자전해질과는 반대 전하를 갖는 형광물질 약 0.001내지 약 750,000ppm을 물에 부가하는 단계; c)수 처리 공정을 수행하여 수성 유출물을 수득하는 단계; d)수성 유출물 중의 형광 물질을 검출하는 단계 및 e)수성 유출물 중의 하전된 형광 물질의 양을 기준으로 하여 고분자전해질의 사용량을 조정하는 단계를 포함함을 특징으로 하여, 오염 물질이 거의 제거된 수성유출물을 생성하기 위한 수 처리 공정에서 고분자전해질의 사용량을 최적화하는 방법.
  2. 제1항에 있어서, 수 처리 공정이 원수 정화, 슬러지 탈수, 에멀젼 파괴 및 색상 제거 공정으로 이루어진 그룹으로부터 선택됨을 특징으로 하는 방법.
  3. 제1항에 있어서, 형광 물질이 음이온성이고, 고분자 전해질이 양이온성임을 특징으로 하는 방법.
