Study on Biogas Production Potential of Lacquer Seed Residues by Anaerobic Fermentation

The research aimed to study the feasibility and potential of biogas production using lacquer seed residue.[Method]Using lacquer seed residue as raw materials,the fermentation experiments were carried out at 30 ℃. During the totally mixed batch fermentation process,parameters of TS biogas production potential,VS biogas production potential,daily biogas output,biogas production rate and pH etc.were determined.[Result]The results showed that on the third day,fermentation system acidated. However,the pH recovered to 7. 0 and led to normal gas production on the seventh day through microbial mediation. After sixty days' fermentation,the biogas production potential reached594. 29 ml /g(TS) and 615. 84 ml /g(VS).[Conclusion] This study proved that lacquer seed residue had good biogas production potential and could be used as raw materials for biogas production.
