Abstract

The invention relates to a waste sludge treatment method for optimising the production of biogas and the quality thereof, as well as the quality of the end sludge obtained. The method comprises the following steps consisting in: performing a hydrolysis and extracting metals from the waste sludge; centrifuging same to separate the supernatant containing metals from the sedimented sludge; and subjecting the sedimented sludge to anaerobic digestion under microaerophilic conditions in a complete-mix anaerobic digester in order to eliminate H2S.
