Abstract

The invention concerns a method and an installation for treating excess sludge coming from biological purification plants. The method is characterised in that it consists in combining at least a step of digestion (4) and at least a step of wet process oxidation (2) of said sludge, said oxidation step being carried out at a temperature ranging between 50 DEG C and 180 DEG C and at a pressure ranging between 2 and 40 bars.
