3、物的比值(Inoculumtosubstrateratios,R,当I/S)有关,其值随着接种比例的减小而逐渐降低接种比例R-1VS,UHS的生物降解率为27.89%~56.29%,其降解能力随着底I/S为0.1颐1~3颐1时,累积甲烷产量为111.20~224.48mL·g物浓度的升高而降低;在高温发酵(55益)和中温发酵(35益)条件下,相同接种比例的对照组中,UHS累积甲烷产量较为接近,但高温发酵的产气速率明显高于中温发酵。关键词:玉米秸秆;水解残渣;厌氧;甲烷;发酵中图分类号:X712文献标志码:A文章编号:1672-2043(2016)03-0584-06doi:10.11654/j
