Process and apparatus for treatment of waste

摘要

A process and equipment for mixing the organic fraction of municipal solid waste with a digesting sewage sludge prior to passing the mixture into an anaerobic digester 15 comprises a vessel 1 having a first inlet 2 for addition of waste, a second inlet 3 in fluid connection with a source of digesting sludge, an outlet 5 for combined waste and digesting sludge and a settlement zone 4. Preferably the outlet for combined waste and sludge is in fluid communication with an anaerobic digestor. In use, a portion of the digestate from the anaerobic digestor is mixed with further waste and then passed through the settlement zone at a velocity sufficient to allow particles to settle.
