Due to the special property of food waste (FW), anaerobic digestion of food waste is facing many challenges like foaming, acidification, ammonia nitrogen and (NH-N) inhibition which resulted in a low biogas yield. A better understanding on the problems exiting in the FW anaerobic digestion would enhance the bio-energy recovery and increase the stable operation. Meanwhile, to overcome the bottle necks, pretreatment, co-digestion and additives is proposed as well as the solutions to improve biogas yield in FW digestion system. At last, future research directions regarding FW anaerobic digestion were proposed.
由于食物垃圾(FW)的特殊性质,食物垃圾的厌氧消化面临着许多挑战,如发泡、酸化、氨氮和(NH-N)抑制,这些导致沼气产量较低。更好地理解食物垃圾厌氧消化中存在的问题将提高生物能源回收并增加稳定运行。同时,为克服瓶颈,提出了预处理、共消化和添加剂以及提高食物垃圾消化系统中沼气产量的解决方案。最后,提出了关于食物垃圾厌氧消化的未来研究方向。
