摘要
随着化石燃料消耗导致越来越严重的全球气候变化问题,可再生能源在近20年被人们大量的研究和探索。通过厌氧发酵处理有机废物产生的沼气作为一种可再生能源得到了广泛的关注。汇总了高温混合厌氧发酵有机废物生产沼气的相关研究,探讨了高温厌氧发酵相比中温厌氧发酵的优点,影响厌氧发酵效率的因素(例如温度、p H值、总固体量、碳氮比和水力停留时间),以及木质纤维素原料的预处理方法对动物粪便和农作物废弃物混合厌氧发酵生产沼气的影响,并描述了厌氧发酵产生沼气过程的数学模型。
With the increasing concerns of global climate change caused by the consumption of fossil fuels,much efforts have been spent on the exploration of renewable energy sources in the last couple of decades. Biogas produced from the treatment of organic waste materials is one of the renewables that have attracted a lot of attentions. This paper provides a summary of the studies on thermophilic anaerobic digestion or co-digestion of various organic waste materials for biogas production. Discussions in this paper include main advantages of thermophilic anaerobic digestion technology over mesophilic one,factors that critically impact the efficiency of the anaerobic digestion such as temperature,pH,total solids,carbon / nitrogen ratio,and hydraulic retention time,the effect of the pretreatment of lignocellulosic materials on the biogas production from anaerobic co-digestion of animal manure and agricultural residues,and mathematical models describing the anaerobic digestion processes.
