| titleOfInvention | Biological nutrient removal process |
| abstract | The present invention relates to a method for biologically treating nutrients in sewage and wastewater, and includes a sedimentation process, a primary sedimentation process, a preliminary denitrification process, an anaerobic bioselective reaction process, an anaerobic contact process, a denitrification / dephosphorization process, and a final sedimentation process. Characterized in that made.n n n The method for treating sewage and wastewater according to the present invention uses sewage and wastewater as a carbon source necessary for denitrification of the returning sludge without introducing various chemicals or external carbon sources, thereby swelling the sludge and controlling the swelling of sludge by maximizing phosphorus elution and inhibiting growth of filamentous fungi. In addition to increasing the dephosphorization efficiency and increasing the sedimentation and concentration of the final sludge, the denitrification in the nitrification process, the denitrification in the final sedimentation process, and the denitrification by denitrification microorganisms (DPRB) can reduce the COD requirements of the denitrification process. The low concentration of sewage and wastewater can be treated, and the size of the denitrification tank can be reduced, thus reducing the initial facility investment cost and facility operation cost. |
