Development of a System to Treat Industrial Wastewater with High Carbonaceous and Nitrogenous Materials

고농도(高濃度) 유기물(有機物) 및 질소(窒素)를 함유(含有)한 산업폐수처리(産業廢水處理) 시스템 개발(開發)

The purpose of this study is to develop a system for treating industrial wastewater with high carbonaceous and nitrogenous materials. To investigate the potential of using this system, a number of experiments are conducted for about 7 months with the varieties of COD and $NH_3-N$ concentrations, and hydraulic retention time. In the system, 1,500mg/L of COD is remover over 95% in a retention time as low as 9 hours, and the $NH_3-N$ removal efficience is nearly 100% with 90mg/L of $NH_3-N$ in the influent. These results illustrate that the system can effectively be used to treat industrial wastewater containing high concentration of COD and $NH_3-N$.
