This article is based on such the idea and is devoted to investigating
the feasibility of biogas production from the antibiotic residue
via HTPT of the residue followed by anaerobic digestion of its
resulting suspension. Laboratory experiments were conducted to
show how the HTPT of a typical antibiotic residue improves its performance
of anaerobic digestion. An analysis was in turn made on
the energy balance for the technical process of HTPT plus anaerobic
digestion based on theoretical calculations and also the data from a
pilot HTPT test. We have also made particular efforts to remove or
minimize the inhibition effects caused by ammonia accumulation
during digestion. As a consequence, a practically possible overall
process was proposed and its technical feasibility was analyzed.
