摘要：通过自主设计的多级厌氧反应器系统来考察半连续处理螺旋霉素工业发酵菌渣的效果。该系统总反应体积为44 L,由4个11 L的升流式厌氧反应罐组成,罐体间采用串联方式连接。121 d的连续运行周期分为3个阶段,各阶段的有机负荷率分别为1.27、1.82和2.73 kg COD/(m3·d)。全过程中主要监测了各级罐体的产气量和螺旋霉素的降解。结果表明,多级厌氧反应器系统启动初期会出现产气不稳定现象,经过2个月的运行之后系统达到稳定状态。在有机负荷达到2.73 kg COD/(m3·d)时,各级罐体仍能稳定运行,总产气的45%集中在1号罐。在系统启动初期,螺旋霉素不能被明显降解。运行约80 d后,整个体系达到了快速降解螺旋霉素的状态,在2.73 kg COD/(m3·d)的有机负荷率下,螺旋霉素降解率达到97%,同时可溶性COD降解率也达到了90%。
Spiramycin manufacturing biowaste was treated by a four stages anaerobic reactor system. The volume of the system was 44 L being divided into four 11 L stages, each of the stage was connected by series. The system was operated with three steps in the organic loading rate （OLR） of 1. 27, 1.82 and 2.73 kg COD/ （ m3 . d）. The process performance of the system was characterised in terms of its biogas volume and spiramycin reduction. The system could reach its stable state in biogas production after two month operation. About 45 per- cent of all biogas was produced from the stage 1 at the OLR of 2.78 kg COD/（m3 . d）. Though spiramycin was not eliminated rapidly at the beginning, after 80 days, an average of 97% spiramycin and 90% COD reduction were achieved at the OLR of 2.78 kg COD/（m3 .d） , indicating that this antibiotic could be degraded efficiently in the anaerobic reactor system.
