초록
In this study, we represents the characteristics of process for a sewage treatment in korea. In case of standard activated sludge process, the results represent that BOD is 90.8%, COD is 82.2%, SS is 95.9% and E-coli is 99.4%. But T-N is 43.3% and T-P is 58.1%. Secondary treatment process shows that BOD is 91.5%, COD is 73.7%, SS is 88.4% and E-coli is 98.1%. But T-N is 35.4% and T-P is 39.6%. The ministry of environment strengthen the disposal criterion of T-N and T-P in sewage. This law shall come into force on January 1, 2012. We know the limits of removal for the N and P in treatment system. It should be reinforced to the advanced process in present plants.
