Abstract
For treating tannery wastewater containing high sulfate and heavy metals, test was performed to assess their performance, competition between SRB (sulfate reducing bacteria) and MPB (methane producing bacteria), and the activity of MPB according to change of chromium concentrations. COD removal efficiency was above 70% at VLR (volumetric loading rate) of 2.0 gCOD/I.day and HRT (hydraulic retention time) of 18hrs at
고농도 황산염과 중금속을 함유한 피혁폐수를 처리하기 위하여, 반응조의 처리도, 황환원균과 메탄균 사이의 기질경쟁 및 크롬농도에 대한 메탄균의 활성을 평가하였다. COD는
