| Title | The study on the effects of various factors on the anaerobic ammonium oxidation process | ||
| Keyword | |||
| Abstract | Anaerobic ammonium oxidation (ANAMMOX) process is an innovative method to remove ammonium from wastewater. ANAMMOX bacteria use ammonium as the electron donor and nitrite as the electron acceptor to convert ammonium to dinitrogen gas under anaerobic condition. Therefore shortcut the biological ammonium removal process and reduce the operation cost of the bioreactor. In this study, ANAMMOX bacteria were cultivated in six months. The factors affecting the nitrogen removal rate of the ANAMMOX bacteria were evaluated via a series of batch experiments. The experimental results indicated that ANAMMOX reaction delayed under high ammonium concentration. The concentration of nitrite over 75 mg/L inhibited the ANAMMOX reaction seriously. Nitrate couldnˇ¦t replace nitrite as the electron acceptor for ANAMMOX reaction in this research. In addition, high phosphate-P concentration (more than 3300 mg/L) or low inorganic carbon source (less than 250 mg/L) inhibited the ANAMMOX reaction also. In addition, the combination of partial nitrification and ANAMMOX reaction was observed under the batch experiments containing ammonium and dissolved oxygen. Keywords: ANAMMOX, Anaerobic ammonium oxidation process, Partial nitrification, Biological nitrogen removal. |
