| Abstract |
Denitrification is an essential part of biological nutrient removal process, however much studies were not conducted particularly in low temperature range. The study was conducted to establish some design data with domestic sewage by adding nitrate as electron acceptor for denitrification at temperatures of 7 to 32℃. Yield coefficients(Y-HD) were varied 0.55 to 0.21gVSS/gCOD removed with endogenous respiration rates of 0.0107 to 0.0339/d. COD requirements for NO₃N removal were increased as temperatures were lowered. Specific denitrification rates were 0.24 to 4.73gNO₃N/㎏VSS/hr. |
