    摘要
  • 摘要: 电化学厌氧消化系统有利于提高餐厨垃圾厌氧消化效率，但不同施电方式对厌氧消化的影响尚不清楚。研究了电化学厌氧消化系统中不同施电方式（恒电压、恒电流）对餐厨垃圾厌氧消化的影响。结果表明：恒电压条件下的累积甲烷产量相比对照组提高了21.43%，根据电化学曲线和导电菌毛合成基因分析结果，这是由于恒压组的内阻更低，电荷转移量更高，具有更高的电子转移效率，从而促进了甲烷产生。恒流条件抑制了餐厨垃圾电化学厌氧消化，这是由于持续施加电流导致电压过高，对微生物的生长代谢产生了不利影响，导致了更低的水解速率以及电子传递速率。微生物群落结构分析表明：恒压组中水解产酸细菌Clostridia和Bacteroidia的总相对丰度比对照组提高了8.55%，包含众多氢营养型产甲烷菌的甲烷微菌纲Methanomicrobia的相对丰度提高了24.58%，这有利于水解产酸和产甲烷反应的进行，促进了H2作为电子供体还原CO2产甲烷的过程。研究成果为推动电化学厌氧消化技术的发展，以及餐厨垃圾的资源化利用提供了新的参考。
    Abstract: Electrochemical anaerobic digestion systems can facilitate the efficiency of anaerobic digestion of food waste， but the effect of different methods of applying electricity on anaerobic digestion is still not clear. The effects of different methods of applying electricity （constant voltage， constant current） on anaerobic digestion of food waste in an electrochemical anaerobic digestion system were investigated. The results showed that the cumulative methane production under constant voltage conditions increased by 21.43% compared with the control group. According to the results of electrochemical curves and conductive bacterial hair synthesis gene analysis， it was due to the lower internal resistance and higher charge transfer in the constant voltage group， which had a higher electron transfer efficiency， thus promoted methane production. The constant current condition inhibited the electrochemical anaerobic digestion of food waste， which was attributed to the high voltage due to continuous application of current， which adversely affected microbial growth and metabolism， leading to lower hydrolysis rates as well as electron transfer rates. The analysis of microbial community structure showed that the total relative abundance of Clostridia and Bacteroidia （hydrolyzing and acid-producing bacteria） in the constant voltage group increased by 8.55% compared to the control group， and the relative abundance of Methanomicrobia （containing numerous hydrogenotrophic methanogens） increased by 24.58%， which promoted the hydrolysis， acid production and methanogenesis reactions， and facilitated the methanogenic process of reducing CO2 with H2 as an electron donor. The research can provide a new reference for promoting the development of electrochemical anaerobic digestion technology and the resource utilization of food waste.
