Abstract

Abstract

In this study, biochar (BC) was prepared by pyrolysis of waste sugarcane bagasse and biochar loaded with nano-zero valent iron (BC-nZVI). The effects of different BC-nZVI dosages (0, 0.1, 0.5, 1 and 2 g/L) on the performance of anaerobic digestion of food waste were investigated under medium and high-temperature conditions and their promotion mechanism was discussed. The results showed that the addition of BC-nZVI significantly increased the cumulative methane production of the anaerobic digestion system and reduced the fermentation delay period. The best results were obtained at 0.5 g/L, with an increase of 36.88% and 45.55% in the medium and high temperature treatments, respectively, compared to the control group. In addition, this study investigated the effect of BC-nZVI on the anaerobic digestion performance of food waste using structural equation modelling. The results showed that fermentation time, NH₄⁺-N, temperature and BC-nZVI significantly affected the cumulative methane production. the porous structure of BC-nZVI has a buffering effect on volatile fatty acids, which helps maintain the system stability and provides growth sites for microorganisms. This study provides a scientific basis for the resource utilization of food waste and a guide for the enhanced anaerobic digestion technology of BC-nZVI.
