一种改性纳米氧化铁颗粒及其在厌氧发酵中的应用
摘要：
本发明公开了一种改性纳米氧化铁颗粒及其在厌氧发酵中的应用。该改性纳米氧化铁颗粒由裸核磁性纳米氧化铁颗粒经过表面修饰后得到，修饰后的氧化铁颗粒带有不同类型的电荷。将改性后的氧化铁颗粒少量添加至厌氧体系，纳米颗粒可促进产酸菌与产甲烷菌的互营进而增加电子传递，促进有机酸向甲烷生成路径转化，提高了系统缓冲能力，增加了系统稳定性，更进一步大幅度提升甲烷产量。
摘要（英）：

The invention discloses modified nano iron oxide particles and application thereof in anaerobic fermentation. The modified nano iron oxide particles are obtained by surface modification of bare core magnetic nano iron oxide particles, and the modified iron oxide particles have different types of charges. A small amount of the modified iron oxide particles are added to an anaerobic system, and thenanoparticles can promote syntrophism of acidogenic bacteria and methanogenic bacteria to further increase electron transfer, promote the conversion of organic acids to methane generation paths, improve the buffering capacity of the system, increase the stability of the system, and further greatly improve the methane yield.
