生物炭对强化有机废弃物厌氧发酵效果的技术研究

Study on Biochar Enhanced Anaerobic Fermentation of Organic Waste

厌氧发酵技术能够将有机废弃物转变成为有用物质,但若有机酸、氨氮等抑制性物质含量较高,可能会造成厌氧菌发酵运行过程不稳定,使得有机物处理效率降低。生物炭表面具有较高的比表面积,表面官能团的活性丰富,导电性较强,能够与环境中的电荷结合,达到吸附的目的。通过阐述生物炭的理化性质,分析其在强化有机废弃物厌氧发酵技术的效果及提升发酵效果的实际应用策略。

Anaerobic fermentation technology can transform organic waste into useful substances,but if the content of inhibitory substances such as organic acid and ammonia nitrogen is high,it may cause the instability of anaerobic fermentation process and reduce the efficiency of organic matter treatment.Biochar surface has high specific surface area,rich activity of surface functional groups and strong conductivity.It can combine with the charge in the environment to achieve the purpose of adsorption.By expounding the physical and chemical properties of biochar,this paper analyzes its effect in strengthening the anaerobic fermentation technology of organic waste and the practical application strategy to improve the fermentation effect.
