Abstract


In order to study the efficiency of dry fermentation reactor treating water hyacinth residue, the anaerobic digestion experiment was performed at ambient temperature and its hydraulic retention time (HRT) was 30 day. The results shown that volume gas productivity of dry fermentation reactor were achieved at 0.6 L/(L·d), the raw material biogas production rate of water hyacinth residue were 41.79 mL/g, the methane content of biogas was 69%. Therefore, the way that the dry fermentation reactor was applied to treat water hyacinth residue was practicable and high efficient, it could provide a new thought for engineering application in the future.
