·
OSTI ID:5928895
A novel process for the purification of waste water and/or waste water sludge comprising subjecting the waste water and/or waste water sludge to first a methane fermentation step, then a denitrification step and finally an oxidation step by aeration, the electron donor in the denitrification step being mainly the sulfide from the methane fermentation step and the remaining reduced compounds in the liquid effluent from the methane fermentation step being oxidized in the aeration step.
