摘要:
作物秸秆等植物源生物质是生物天然气(沼气)生产的重要原料,但因其固有的收获季节性、时效性等特点无法满足可持续供给的生产要求,必需进行跨季节贮存。为了更好地衔接生物质原料贮存与沼气化利用环节,打通生物质沼气化利用上-下游链条的任督二脉,评述了生物质常见的干法保存和湿法保存方法,并根据原料形态特征差异性着重总结了常规青贮、半干青贮、黄贮、混合贮存等湿法贮存技术的研究现状,从乳酸菌剂、生物酶制剂、化学添加剂、复合添加剂等角度探讨了贮存过程的调控策略。最后,总结比较了青贮过程以及多元化调控策略对生物质原料产沼气(甲烷)性能的影响。目前,有关生物质青贮和青贮原料厌氧消化工艺的研究较为广泛,但由于生物质原料种类繁多,组分复杂多变,二者上-下游之间的具体关联机制尚不完全明确,未来需要根据不同物料特性来揭示这种联系机制,并从源头上实现基于沼气生产的贮存过程调控,以其获得能量保存和能源转换的最大化。总之,湿法贮存是生物质原料长时间保存的重要方法,对生物天然气产业快速健康发展具有重要的科学价值和实际意义,沟通贮存与沼气发酵过程上下游之间的衔接机制是该领域未来的研究发展方向。(表3 参84)
Abstract:
Biomass, such as crop straw, is an important raw material for the biogas production by anaerobic digestion . The trans-seasonal storage requirements of biomass are critical for a year-round continuous supply of feedstock for biogas plants throughout the year , in some cases even of extended durations because of its inherent seasonal harvest characteristics. Therefore, how to realize sustainable supplementation of biomass is the primary task. In order to connect the link of biomass storage and biogas utilization and break through key conception and governor vessels between the downstream and upstream systems of biogas plants, the preservation method, including dry and wet storage, were reviewed in detail. Furthermore, the wet storage method, such as ensiling, hay silage, co-ensiling, were emphatically analyzed according to the different characteristics of various biomass. On this basis, a series of strategies for process regulation during storage were explored in terms of lactic acid bacteria, bio-enzyme, chemical additives, compound additives, etc., so as to achieve the goal of high-quality, long-term preservation, and obtain favorable energy conversion efficiency. Moreover , the effects of ensiling process and diversified regulation strategies on biogas production performance were summarized, and the biogas production performance before and after storage was compared. At present, the trans-seasonal storage and anaerobic digestion process of biomass are be widely investigated respectively, but the correlative mechanism between the upstream and downstream is not fully clear, which was imperative to be evaluated according to the biomass properties to maximize energy conservation and energy conversion. In conclusion, ensiling of biomass, the wet-storage method, is an effective method of preserving the nutrient and ensuring sustainable supplementation , the correlative mechanism between storage and downstream biogas fermentation are the main research orientation in the future.
