摘要：
This study investigated different solid retention time (SRT) on municipal solid waste (MSW) anaerobic digestion with various MSW incinerator fly ash (FA) and bottom ash (BA) addition. Results showed that biogas production rates (BPRs, similar to 200 to similar to 400 mL/gVS) with organic loading rate of similar to 0.053 gVS/gVS(reactor) (Day 1-435, SRT 20 days, SRT20) at FA 1 g/d (FA1), BA 12 g/d (BA12) and BA 24 g/d (BA24) dosed bioreactors increased after adaptation. BPRs with SRT10 and SRT5 decreased while BPRs with SRT40 showed to increase compared to initial BPRs (similar to 200 mL/gVS) with SRT20. SRT5 operation reduced the BPRs (similar to 10 - similar to 90 mL/gVS) significantly and only BA12 and BA24 dosed bioreactors could recover the BPRs (similar to 100 - similar to 200 mL/gVS) after SRT20 operation (Day 613-617) compared to FA1 and FA3 and control. Released levels of Co, Mo and W at BA12 and BA24 dosed bioreactors showed most potential to improve MSW anaerobic digestion. (C) 2012 Elsevier Ltd. All rights reserved.
