Process for the treatment of sewage sludges or industrial sludges with organic constituents by means of the conversion process

摘要

The invention relates to a process for the treatment of sewage sludges and/or industrial sludges with organic constituents by means of the conversion process, in which a) the sludges are subjected to initial mechanical dewatering and are dried (4), b) fed into the interior of an indirectly heated continuous transporter (7), where c) in a first zone in the form of a heating zone, heating to the conversion temperature with simultaneous expulsion of readily volatile components from the solid product takes place and d) in the second zone, acting as the conversion zone, the sludges remain at the conversion temperatures in order to expel the remainder of the volatile components from the solid product, and to an apparatus for carrying out the process.
