Abstract
As the effluent quality standard of the municipal wastewater treatment plant (MWTP) has been strengthened, the treatment of the recycle water containing high concentration of ammonium nitrogen has been considered as one of retrofit methods for upgrading the exising MWTPs. In this study, nitritation, economic nitrogen removal process, was induced by laboratory-scale reactor at the 35oC, 20oC, and 10oC temperature conditions using anaerobic digester supernatant. The stable nitritation was achieved over 20oC, but nitrification was induced at 10oC. It means that the nitritation was affected by SRT and temperature. SRT, demanded for nitritation, is changed according to the temperature. Therefore, it is considered that SRT and temperature are important factors in nitritation. Also, it is approved that inducing the ammonium nitrogen removal and the nitritation are more beneficial over 20oC.
The conclusion of this study can be used for the important basic reference when nitritation process is applied for MWTPs.
