영문 초록

This study were performed to control color and satisfy discharge permission standard of effluents operating a small dyeing factory based on a fiber. The color removal efficiency was very high when the injection site of Sodium Hypochlorite(NaOCl) was more discharge site of second sedimentation tank than of first sedimentation tank. Although NaOCl usages was reduced from 1.0 ㎥/day to 0.8 ㎥/day, the removal efficiency of BOD, COD and SS were similar. At the time, the optimal Hydraulic Retention Time(HRT) was calculated to twenty five minute after NaOCl injection until effluent discharged finally. After controlling NaOCl usages and HRT, the effluent quality of BOD, COD, SS, Color and Chloroform were 8.6 mg/L, 24.7 mg/L, 43.3 mg/L, 191.2 degree and 0.346 mg/L, respectively, so that was satisfied to discharge permission standard.
