초록

2021년부터 총유기탄소(TOC)가 국내 공공하수처리시설의 새로운 유기물질 기준 지표로 선정됨에 따라, 기존 유기물질 관리지표(DOC, BOD5, CODMn, CODCr)와의 상관성 분석을 통해 TOC의 적용 타당성 평가가 필요하다. 본 연구에서는 500개소 공공하수처리시설을 공정 및 시설용량에 따라 구분하여 유입 및 방류수에 대한 유기물질 관리지표간의 상관성 분석을 실시하였다. 다른 유기물질 관리 지표 대비 유입수와 방류수 내 화학적 산소요구량(CODMn)와 TOC간 농도비와 결정계수(R2)는 상대적으로 높았다. 유기물질 관리지표간의 상관성 결과는 새로이 기준으로 도입된 TOC와 관련된 다양한 연구 수행에 기초자료로 활용될 것으로 기대된다.

As the total organic carbon (TOC) becomes a new water quality standard as an organic matter (OM) index for public sewage treatment facilities (PSTFs) in Korea from 2021, a comparison study needs to be conducted by examining the correlation between TOC and the existing OM indices (DOC, BOD5, CODMn, CODCr). 500 PSTFs were categorized by process configuration and capacity, and correlation between OM indices in influent and effluent was analyzed. The CODMn/TOC showed higher correlation than other OM indices. This results can be used to basic data for various research associated with TOC.
