A process and apparatus for treating biosolids from biological wastewater treatment. The temperature of autothermal aerobic treatment of biosolids is controled by sensing the oxidation/reduction potential of the solution and adjusting the amount of oxygen or biosolids supplied to the solution through a jet aerator (1) having a liquid header (3) for the recirculation of the solution and an air header (5).
L'invention concerne, de manière générale, un procédé et un appareil de traitement des biosolides issus du traitement des flux d'eaux usées biologiques. La régulation de la température du traitement aérobie autothermique des biosolides se fait par détection du potentiel d'oxydoréduction de la solution et par réglage de la quantité d'oxygène ou de biosolides fournie à la solution via un dispositif d'aération (1) par jet équipé d'une colonne (3) de liquides pour le recyclage de la solution et d'une colonne (5) d'air.
