摘要
The goal of this study was to investigate the influence of the fermenter concepts on the biogas production from duckweed. A fixed bed reactor (FBR) and a continuous stirred tank reactor (CSTR) in laboratory scale, both continuously running, were tested with regards to technical feasibility and biogas production. The duckweed was co-fermented with cattle slurry. The biofilm of the FBR had probably a stabilizing influence during a phase of reduced reactor volume, while the CSTR showed a decline in the biogas production. Over the last 25 day of the trial each reactor produced 273 ml (STP) / gVS biogas. The methane content in the FBR was 63.8 % and 63.1 % in the CSTR. Theoretical methane potentials were calculated based on nutritional value analysis and compared to dis-/continuous digestion tests.
