SEPTIKTANK OMFATTENDE SLAMSIRKULATOR MED GASS-SUPPLEMENT

摘要

An anaerobic sludge digester (10) including a digester tank (1) and a sludge mixing system (26) for hydraulically mixing the contents of the digester tank and for agitating the surface of the sludge in the digester tank. The mixing system (26) includes a sludge supply assembly (28) and a gas supply assembly (48) for respectively supplying sludge and gas derived from the tank to a common distribution network (56) for discharge back into the tank. The distribution network includes a plurality of distribution pipes (72) and a sequencing mechanism (58,78) for simultaneously delivering a sludge and gas mixture to the pipes one at a time and in sequence.
