Abstract

Abstract

At present, in the process of food waste treatment, the situation that anaerobic digestion microorganisms coated by lipids often occurs. After lipids extraction, a large amount of lipids still enters the digestion system, which causes certain harm to the stability of the system. To alleviate this problem, the promoting effect of electric pretreatment on anaerobic digestion of high lipid content food waste was studied in this research. Compared with the untreated group, the methane yield of food waste (50% of lipids) treated with 0.8 V increased by 6.5% from (780.43±4.49) mL/g TVS to (831.06±13.85) mL/g TVS. The peak methane production rate increased by 20.3%, from (35.84±0.64) mL/(g TVS·d) to (43.11±0.72) mL/(g TVS·d). The time to reach the peak rate was reduced from 20 days to 14 days. The results showed that in a certain range of added lipids (0 to 50%), with the increase of lipids content, electric pretreatment demonstrated a better promoting effect on anaerobic digestion. Microscopic images showed that a large number of microorganisms were attached to the electrode surface at a voltage of 0.8 V, while no microorganisms were observed in the untreated group. According to the results of the three-dimensional fluorescence spectrum test, utilization of metabolic substrates such as humic acid was significantly improved at a voltage of 0.8 V. The promoting effect of voltage on the anaerobic digestion of high lipid content food waste can be explained from three aspects: enhancing the contact between microorganisms and electrodes, promoting the acidification and degradation of lipids, and improving the electron transfer through acetoxylation and methanation pathways.
- high lipid content food waste,
- anaerobic digestion,
- electric pretreatment,
