Abstract

La présente invention concerne un procédé et un appareil correspondant pour la digestion anaérobie d'un déchet organique. Cet appareil comprend un réacteur d'hydrolyse (14) dans lequel le déchet organique est soumis à une hydrolyse avant que la fraction liquide du produit sortant du réacteur d'hydrolyse ne soit transférée à un réacteur anaérobie (19). La fraction solide du produit sortant du réacteur d'hydrolyse est éliminée au moyen d'un séparateur (16). La sortie de liquide provenant du réacteur anaérobie est retournée par une canalisation de retour (34) après un éventuel chauffage par un système de chauffage (35), afin d'être mélangée au flux d'influent de la matière à traiter. La matière d'afflux est macérée dans un système de macération (14), puis est émulsionnée dans un système émulseur (11) avant d'être transférée au réacteur d'hydrolyse (14).
