ABSTRACT:
A process for recycling raw sewage and unsorted solid waste by adding the solids removed from sewage to ground unsorted waste forming a sludge, treating the sludge first anaerobically, sterilizing the anaerobically treated sludge, forming the sludge into a slurry, separating the biodegradable from the non-biodegradable material in the slurry by aerobic fermentation, composting the biodegradable material in batches, curing the compost under control conditions to stabilize its fertilizing properties and classifying the biodegradable and non-biodegradable material to provide useable products. The colloidal raw sewage liquor remaining after separation of the sewage solids is converted into pure water.
