Performances of two-phase SBMR-ASBR anaerobic digestion for biogas production of kitchen waste
摘要
Abstract
The performances of two-phase SBMR-ASBR anaerobic digestion for biogas production of kitchen waste was investigated. To find out the acid production performances of acidification phase and the methane production performance of methanogenic phase, kitchen waste from campus restaurant was used as feedstock. The results showed that the acidification phase of kitchen waste . entered into a stable ethanol-type fermentation rapidly and avoid the propionate-type fermentation at a high OLR. The acid yield was 55 000 mg/L with 10 g/(L·d) of OLR at the stable state. Ethanol and acetic acid were 27 000 mg/L and 23 000 mg/L in VFA, respectively. Ethanol and acetic acid were 91% of VFA. The stable OLR of the methanation phase was 5 g/(L·d) in this condition. The OLR of the system was 3.3 g/(L·d). The volume gas production rate arrived at 23 L/(L·d). Methane content was 65%~70%. Removal rate of TS and VS reached 77% and 83%, respectively. It is suggested that the acidification be started at a high OLR, and this is beneficial to the system to build a stable ethanol-type fermentation and a methane phase running at a high OLR. The acidification phase running at high OLR would be recommended in facility of municipal organic solid waste.关键词
