芦笋秸秆预处理与厌氧发酵制取沼气试验（Experiments on Pretreatment and Anaerobic Digestion of Asparagus Stalk for Biogas Production）
芦笋 秸秆 厌氧发酵 沼气
2010/12/28
为了促进芦笋秸秆原料沼气发酵系统的产气效果，利用NaOH在无流动水的条件下对芦笋秸秆进行了碱性化学预处理，并在小型沼气发酵装置上以不同预处理时间、粒径和NaOH溶液质量分数对芦笋秸秆木质纤维素的变化及产沼效果的影响进行了试验研究。结果表明，预处理时间15~20d比不经预处理的试验组启动时间提早10d；芦笋秸秆粉碎和切割后，不经筛分的试验组比经过筛分后的试验组启动时间提早5~15d，发酵周期缩...

温度对蔬菜废弃物沼气发酵产气特性的影响（Effects of Temperature on Anaerobic Fermentation for Biogas Production from Cabbage Leaves）
蔬菜废弃物 厌氧发酵 沼气
2009/9/25
运用实验室自行设计的小型沼气发酵装置，以废弃的甘蓝菜叶作为发酵原料，研究了温度对蔬菜废弃物沼气发酵产气特性的影响。结果表明，中温条件(（35±1)℃）试验组的挥发酸质量浓度、氨态氮质量浓度以及pH值都在正常范围内，且优于高温(（55±1)℃）和室温发酵试验组，可保证系统的顺利运行。产气特性研究表明：中温条件的总产气量比高温条件总产气量高42.5%，最高甲烷含量比高温条件和室温条件下分别高7.6%和...
牛粪、鸡粪和稻秆混合的沼气发酵特性与工艺优化（Fermentation and Process Optimization of Mixed Cow Dung,Chicken Manure and Rice Straw for Biogas Production）
沼气发酵 牛粪 鸡粪 稻秆 温度 配比
2010/4/1
采用可控恒温厌氧发酵装置，选用牛粪、鸡粪、稻秆3种原料，按干物质比例0∶2∶1、0.4∶1.6∶1、0.8∶1.2∶1、1.2∶0.8∶1、1.6∶0.4∶1、2∶0∶1混合，研究了各配比在15℃、20℃、25℃、30℃下的厌氧发酵情况。结果表明：随温度升高，各配比产气速率和累积产气量均增大，15℃下发酵周期最长，其他温度对发酵周期影响无显著差异；不同配比下，累积产气量均呈先增大后减小的趋势，牛粪...
