摘要
沼气是一种重要的可再生清洁能源。添加纳米颗粒(Nanoparticles,NPs)可提高沼气产量,特别是金属NPs在提高沼气产量、缩短启动周期、改善工艺稳定性方面具有较大潜力。不同类型、大小和浓度的纳米颗粒对于提高沼气产量和厌氧消化效率至关重要。本文阐述了导电NPs的类型和大小对改善厌氧消化系统内微生物生长、CH_(4)产生、生物量转化率以及营养代谢的影响,并讨论了厌氧消化(Anaerobic Digestion,AD)系统中添加NPs的限制和影响因素。
Biogas is an important renewable clean energy. Adding nanoparticles can improve biogas production,especially metal nanoparticles have great potential in improving biogas production, shortening start-up cycle and improving process stability. Different types, sizes and concentrations of nanoparticles are very important to improve biogas production and anaerobic digestion efficiency. This paper will deeply elaborate the effects of the type and size of conductive NPs on improving microbial growth, CH_(4) production, biomass conversion and nutrient metabolism in Anaerobic Digestion(AD) system, as well as the limitations and considerations when adding NPs to ad system.
