영문 초록

The purpose of this study is to get basic data for the application of coagulants for treating an industrial wastewater containing NBD COD. The NBD COD concentration of the target wastewater was calculated to be 61 mg/L, which was about 72% of the first stage treated water, and this shows that there must be advanced wastewater treatment process. When Alum(8%) was injected in raw the water, 150ppm was the best dosage and 41% CODmn removal efficiency was obtained. When Alum(8%) was injected in the discharge water, 150ppm was the best dosage, and 19% CODmn removal efficiency was obtained. When powdered activated carbon was injected, 40ppm was the best dosage, 26% CODmn removal efficiency was obtained. The method of injecting Alum(8%) in the discharge water was suitable, when the effluent exceeds the water quality standard by 20%, and the method of injecting the powdered activated carbon was suitable, when the effluent exceeds the water quality standard by 20~40%.
