Title (EN) PROCESS FOR THE TREATMENT OF WASTEWATER CONTAINING ORGANIC MATERIAL AND AMMONIA
(FR) PROCÉDÉ DE TRAITEMENT D’EAUX USÉES CONTENANT DE LA MATIÈRE ORGANIQUE ET DE L’AMMONIAC
Abstract:
(EN) Wastewater containing a significant level of dissolved readily biodegradable organic compounds matter, such as short-chain fatty acids, and ammonia can be efficiently treated to remove most or all of the organic compounds and the ammonia, with the production of microbial storage compounds such as polyhydroxyalkanoates, by (i) subjecting the wastewater storage compound-accumulating microorganisms (SCAM) in the presence of oxygen, (ii) subjecting at least part of the resulting partly treated wastewater to ammonia-oxidising microorganisms (AOM) in the presence of oxygen and (iii) feeding a gas containing molecular carbon dioxide produced during step (ii) to step (i) so as to lower the pH in step (i).
(FR) La présente invention concerne des eaux usées contenant un niveau significatif de matière composés organiques biodégradables rapidement dissous, tels que les acides gras à courte chaîne, et de l’ammoniac pouvant être efficacement traitées pour retirer la plupart ou tous les composés organiques et l’ammoniac, avec la production de composés de stockage microbiens tels que les polyhydroxyalcanoates, en (i) soumettant les micro-organismes d’accumulation de composés de stockage d’eaux usées (SCAM) en présence d’oxygène, (ii) en soumettant au moins une partie des eaux usées partiellement traitées résultantes aux micro-organismes oxydant l’ammoniac (AOM) en présence d’oxygène et (iii) en alimentant un gaz contenant le dioxyde de carbone moléculaire produit durant l’étape (ii) à l’étape (i) afin de réduire le pH dans l’étape (i).
