SYSTEM FOR AUTOTHERMAL THERMOPHILIC AEROBIC DIGESTION, AND ASSOCIATED METHOD

摘要

The invention relates to a system for autothermal thermophilic aerobic digestion, for the hygienisation of sludge, which allows the non-treated sludge to be pre-heated in the digestion tank where the aerobic digestion of the sludge takes place under thermophilic conditions without any external energy input since it uses the residual heat present in the sludge that has already been treated in order to pre-heat the sludge before it is introduced into the digestion tank. The invention also relates to the method associated with said system.
