Process for treating ammonium containing liquid |
摘要 |
The process for treating an ammonium containing liquid of the present invention can perform high-speed denitrification of an ammonium containing liquid by anaerobic ammonium oxidation or the like, without being affected by the change in concentrations of nitrogen components in the ammonium containing liquid to be treated, and can provide a treated liquid with high quality constantly stably. The process comprises reduction of nitrate contained in or added to the ammonium containing liquid to nitrite, and simultaneously anaerobically denitrifying nitrite produced in the nitrate reduction treatment and ammonium contained in the ammonium containing liquid by anaerobic ammonium oxidizing bacteria. |
