BIOFILTER DEVICE AND SEWAGE SLUDGE RESIDUE DEHYDRATION FILTRATE TREATMENT SYSTEM USING THE SAME

摘要

To provide a biofilter device capable of recovering fine organic particles, which can be repeatedly used without clogging of the filter, and a sewage sludge residue dehydration filtrate treatment system using the biofilter device.SOLUTION: A biofilter device 1 comprises a biofilter 2 provided with a fungus body habitat medium 4 inhabited by aerobic bacteria, in which the fungus body habitat medium 4 includes a fermentation sewage sludge residue pellet produced by fermenting a bacteria-carried sewage sludge residue pellet with bacillus bacteria carried inside a sewage sludge residue pellet and lactic acid bacteria carried on the surface part. There is also provided a sewage sludge residue dehydration filtrate treatment system using the same.SELECTED DRAWING: Figure 1
