하·폐수 처리장에서 질소 농도를 저감시키는 가장 효율적 방법은 무엇인가? | 하·폐수 처리장에서 배출되는 총 질소 농도를 저감시키기 위한 가장 효율적인 방법중의하나는 반류수 내 고농도 질소 성분을 제거하는 것이다 (Rosén et al.,1998). | |
ANAMMOX 미생물 관련 대표적 공법은 무엇이 있는가? | , 2001).대표적으로 sequencing batch reactor (SBR), attachedgrowth biofilm reactor, upflow granular sludge reactor공법 등의 형태로 많은 상용 규모 공법이 설치되어 운전 중에 있으며, 대부분은 SBR 공법을 근간으로 가장 많은 상용화 실적을 보유 중에 있다 (Lackner et al.,2014). | |
세계적으로 효율적 질소 제거 방법이 요구되는 이유는 무엇인가? | 국내 하·폐수 처리장에서는 2003년부터 전국적으로 총 질소에 대한 배출허용 기준이 적용되어 왔고, 현재 질소의 배출허용기준은 동절기를 포함하여 TN 20 mg/L로 설정되어 있다. 하지만 전세계적으로 급속한 인구증가와 도시화로 인해 자연계로 유입되고 있는 질소의 양이 급속히 증가되고 있는 반면, 배출허용기준은 점차 강화되고 있어, 보다 효율적인 질소 제거 방법은 요구되고 있는 실정이다 (Choi et al., 2011; Wang et al. |
