<p>Method of treatment of waste water, using activated sludge, comprising a process of oxidation of the carbonaceous contaminants and a nitrification process, optionally in combination with a denitrification and/or dephosphatation process. …<??>This process comprises a reaction stage during which decontamination reactions take place, a sludge concentration stage, a generation stage during which the sludge is aged and/or a stage of initiation of the reactions which are developed during the reaction stage. Waste-water purification station comprising a tank in which the decontamination operations take place (1), a tank for sludge aging and/or the initiation of the decontamination reactions (4) and an apparatus for concentrating the sludge, mounted as a loop (3). …<??>Application to the biological purification of residual waste water.</p> |
