Abstract

Διαδικασία που εφαρμόζεται για την επεξεργασία των αστικών αποβλήτων, η οποία περιλαμβάνει τις ακόλουθες φάσεις: να υποβάλουμε τα απόβλητα αυτά καθεαυτά σε μια πρώτη αναερόβια επεξεργασία χωρίς κάποια πρωτογενή ιζηματοποίηση, να επιτελέσουμε στη συνέχεια μια μη οξική ενδιάμεση φάση και να επεξεργασθούμε την απορροή από αυτή την ενδιάμεση φάση με μια τελική αερόβια φάση.ωA process applied to the treatment of municipal waste, which includes the following phases: to subject the waste itself to a first anaerobic treatment without any primary sedimentation, to then carry out a non-acetic intermediate phase and to treat the effluent from this intermediate phase with a final aerobic phase.o
