Abstract
K leather industry wastewater treatment plant(advanced treatment process) was selected to evaluate effluent quality and pollutants removal efficiencies. $BOD_5$ concentration of effluent was $3.95mg/{\ell}$ and its removal efficiency was 99.8%. Also, most of other pollutants removal efficiencies were over 90% as well. And 95% reliability of effluent concentration were $106.8mg/{\ell}$ of CODmn, $86mg/{\ell}$ of SS, $72.04mg/{\ell}$ of TN that is greater than the effluent limitation, $0.98mg/{\ell}$ of ABS, $1.8mg/{\ell}$ of n-Hexane, $9.7mg/{\ell}$ of $BOD_5$ and $0.11mg/{\ell}$ of Cr.
