Abstract:

The possibility of using activated sludge immobilized in porous ceramic carriers in nitrification of ammonia present in municipal wastewater was investigated. Three different carriers made the stable filling of three column reactors with internal circulation. The properties of the carriers such as internal structure, size of active surface, and participation of hollow spaces in the carrier volume determined the effect of volumetric organic and nitrogenous loading on the loading of nitrogen oxidized. Key words: immobilized activated sludge, porous ceramic carriers, municipal wastewater, nitrification.

La possibilité d'utiliser des boues activées piégées dans les transporteurs en thermo-mousse pour la nitrification de l'ammoniaque dans les eaux usées municipales est examinée. Trois différents transporteurs remplissaient trois réacteurs en colonne à circulation interne. Les propriétés des transporteurs, telles que la structure interne, la dimension de la surface active et la proportion de vides dans le volume du transporteur, déterminent l'effet du chargement volumétrique organique et azoté sur le chargement de l'azote oxydé. Mots-clés : boues activées piégées, transporteurs en thermo-mousse, eaux usées municipales, nitrification.[Traduit par la rédaction]
