PROCEDE DE TRAITEMENT D'UN EFFLUENT METTANT EN OEUVRE UNE NITRIFICATION/DENITRIFICATION SIMULTANEES DANS UN BIOFILTRE |
摘要 |
The invention concerns biological treatment by nitrification/denitrification of an effluent comprising a step which consists in passing said effluent through a biological reactor with micro-organisms fixed on at least a granular material bed provided with means supplying oxygen. The invention is characterised in that it consists in: aerating substantially continuously said granular material bed assembly; measuring at least a parameter representing the oxygen consumption of said fixed micro-organisms and a step which consists in regulating the functioning of said oxygen supply means according to the results of said parameter measuring step and a set value thereof, said method enabling substantially simultaneous nitrification/denitrification of said effluent.
