摘　　要：开发了基于机械生物处理法的玉米秸秆利用技术,该技术将玉米秸秆加工为机械浆、葡萄糖和木糖。首先对风干的玉米秸秆进行单螺旋搓丝和筛分,实现皮瓤分离,所得皮、瓤的质量比为1∶8;所得的玉米秸秆皮进行机械磨浆和0.18 m m缝筛精制,所得纸浆相对玉米秸秆的得率为75%。硫酸盐针叶木浆和玉米秸秆机械浆进行配抄,针叶浆加入量为20%时,纸浆撕裂指数为6.0 m N.m^(2)/g、抗张指数为22.7 N.m/g。所得的玉米秸秆瓤加入纤维素酶和木聚糖酶进行酶解糖化,50℃、48 h的葡萄糖产量为37.5 kg/t玉米秸秆瓤,木糖产量为16.28 kg/t玉米秸秆瓤。In this study,a technology for utilization of corn straw based on mechanical biological treatment was developed,which processed corn straw into mechanical pulp,glucose and xylose.The air-dried corn straw was first separated by single spiral rolling and sieving to achieve a skin-to-flesh ratio of 1:8.The corn straw skin was mechanically milled and refined by 0.18 mm slit sieve,resulting in a pulp yield of 75%relative to corn straw.The pulp tear index was 6.0 mN·m^(2)/g and tensile index was 22.7 N·m/g when the pulp was copied with sulfate coniferous pulp and corn straw mechanical,which the sulfate coniferous pulp accounted for 20%.The corn straw flesh was enzymatically saccharified by adding cellulase and xylanase,and the glucose yield was 37.5 kg/t corn straw flesh and the xylose yield was 16.28 kg/ton corn straw flesh at 50°C and 48 h.
