Abstract
SYSTEME ET PROCEDE DE TRAITEMENT DE DECHETS SOLIDES, DE MATERIAUX BIOLOGIQUES ET DE PRODUITS ANALOGUES ET DE TRANSFORMATION DE CES MATERIAUX TRAITES EN UN GAZ CONTENANT DU METHANE. DES DECHETS SOLIDES CONTENANT A LA FOIS DES CONSTITUANTS INORGANIQUES ET DES CONSTITUANTS ORGANIQUES SONT AMENES DANS UNE INSTALLATION DE RECEPTION OU ILS SONT INITIALEMENT REDUITS EN MORCEAUX ET SOUMIS A UN STADE DE SECHAGE REPRESENTE DE MANIERE GENERALE EN 10. LE STADE 10 EST EFFECTUE DANS UN DISPOSITIF A UNE OU PLUSIEURS VOUTES INDIQUEES EN 12, CHACUNE AYANT UNE PORTE D'ACCES 14 DISPOSEE VERS LE HAUT. LA VOUTE S'ETEND DANS LE SENS LONGITUDINAL SUR UNE CHAMBRE SOUS PRESSION 16. APPLICATION A LA PRODUCTION DU METHANE.
