Abstract:

以稀释糖蜜为底物,通过厌氧接触式发酵制氢反应器(ACR)的启动和运行,考察了ACR在不同进水COD浓度下的运行特性。结果表明,当HRT=6h,进水COD浓度从7000mg·L-1提升至11000mg·L-1时,反应器仍能稳定运行,并维持乙醇型发酵类型。随着底物浓度的增加,系统的比产氢速率从COD7000mg·L-1时的2.43m3·(m3·d)-1提高到COD11000mg·L-1时的3.51m3·(m3·d)-1,而活性污泥的比产氢速率在COD为9000mg·L-1时最高,为10.71molH2·(kgVSS·d)-1。聚合酶链式反应-变性梯度凝胶电泳(PCR-DGGE)分析结果表明,产氢发酵产乙醇菌群为ACR系统中的主要产氢功能菌群,且随着进水COD浓度的增加,以EthanoligenensharbinenseYUAN-3为代表的产氢菌群的优势度显著增强,但丙酸发酵菌属Propionicimonassp.F6也开始富集。
