Abstract
The invention concerns a novel isolated microorganism characterized in that it is capable of: i) transforming Kjeldahl nitrogen, ammonia nitrogen and/or nitrogen oxides into gas nitrogen; and ii) transforming carbonaceous matter into carbon dioxide; both transformation processes being carried out in aerobic condition. The invention also concerns a method for treating wastewater using said microorganism.
Claims29
Isolated microorganism characterized in that it is capable of achieving:
- i) the conversion of Kjeldahl nitrogen, ammoniacal nitrogen and/or nitrogen oxides to gaseous nitrogen;
- and
- ii) the conversion of the carbonaceous matter to carbon dioxide;
- the two conversions taking place under aerobic conditions.
(canceled)
The wastewater treatment method according to claim 21 for the conversion of Kjeldahl nitrogen, ammoniacal nitrogen and/or nitrogen oxides contained in the wastewater to gaseous nitrogen, under aerobic conditions.
The wastewater treatment method according to any one of claims 21 and 10 to 14, characterized in that no external carbonaceous source is added to the wastewater for treatment.
The wastewater treatment method according to claim 21, characterized in that the treatments take place in a single free activated sludge tank.
The wastewater treatment method according to claim 21, characterized in that the treatments take place in a culture device fixed on a support.
The wastewater treatment method according to claim 21, characterized in that the microorganism is produced by continuous culture beforehand.
