摘要:

沼气厌氧消化过程涉及复杂微生物群落在厌氧环境下的协同作用,此过程中的因素变化会导致菌群结构发生改变,进而影响发酵系统的稳定性和效率。本文对影响厌氧发酵过程稳定和效率的因素进行了探讨,包括发酵温度、pH值、碳氮比、有机负荷、停留时间及营养元素等。认为厌氧发酵过程采用混合原料可以弥补单一原料发酵过程的养分不足和特定成分积累对发酵过程稳定性的影响;在发酵温度的选择上,要充分考虑能源输入/输出比,才能保证过程的经济性。

Abstract:

Biogas anaerobic digestion (AD) process involves in synergy of complicated microorganism communities in anaerobic condition. Factors variation of the AD process may cause the variation of community composition, which may further affect stability and efficiency of a fermentation system. We address the factors affecting stability and efficiency of biogas AD process, including fermentation temperature,pH value,C/N ratio,OLR and retention time, macronutrients and trace elements.Mixed raw materials in AD process can compensate nutrient deficiency of single raw material and the impact of specific component accumulation on AD process stability. For temperature selection of AD process, if input and output energy ratio is fully considered, economy of AD process can be guaranteed.

Key words: biogas, influential factor, anaerobic digestion
