Abstract

폐수의 생물학적 탈질, 탈인 처리방법에 관한 것으로 폐수(5)를 유동상 혐기성 반응조(1)와 혐기성 반응조(2)에 처리한후 유동상 호기성 반응조(3)에서 처리하여 이를 침전조(4)에서 고액분리하여 슬러지의 일부 또는 전부를 유동상 혐기성 반응조(1)에 순환하여 처리하는 것을 특징으로 하는 폐수의 생물학적 탈질, 탈인 처리방법.

Description

폐수의 생물학적 탈질, 탈인 처리방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 공정도.
제2도는 제1도의 부가적인 변법에 대한 공정도.
제3도는 종래의 질소와인 제거 공정도.

Claims (4)

  1. 폐수(5)를 유동상 혐기성 반응조(1)와 혐기성 반응조(2)에서 처리한 후 유동상 호기성 반응조(3)에서 처리하여 이를 침전조(4)에서 고액분리 하여 슬러지의 일부 또는 전부를 유동상 혐기성 반응조(1)에 순환하여 처리하는 것을 특징으로 하는 폐수의 생물학적, 탈질, 탈인 처리방법.
  2. 제1항에 있어서, 유동상 혐기성 반응조(1)에 유동상 호기성 반응조(3)의 처리수를 순환시키는 것을 특징으로 하는 폐수의 생물학적, 탈질, 탈인 처리방법.
  3. 제1항에 있어서, 반응조 부피를 작게 하기 위해 혐기성 반응조(2)를 유동상 반응조로 변경하거나 유동상 혐기성 반응조(1)의 순환수(6)를 하부에서만 유동시켜 상부를 혐기성 반응조(2)로 하는 것을 특징으로 하는 폐수의 생물학적, 탈질, 탈인 처리방법.
  4. 제1항에 있어서, 인의 처리율을 높이고자 유동상 호기성 반응조(3)의 처리수나 유출수에서 화학응집 처리를 하는 것을 특징으로 하는 폐수의 생물학적, 탈질, 탈인 처리방법.
