本研究评估了利用厌氧消化（AD）工艺从墨西哥城中央食品配送市场获得的水果和蔬菜废物（FVW）生产甲烷的可行性。分批系统表明，pH值控制和氮添加对生物气产量，甲烷产量和挥发性固体（VS）从FVW去除（0.42 m（生物气）（3）/kg VS，50%，和80%，分别）有显着的影响。共消化的FVW与肉渣（MR）增强了工艺性能，并在30 L AD系统中进行了评估。当系统达到稳定运行时，其甲烷产率为0.25（m3/kg TS），以总化学需氧量（tCOD）测量的有机物去除率为65%。还测定并表征了30 L系统中的微生物种群（一般细菌和芽孢杆菌），并与其在AD系统中的潜在功能密切相关。(C)2011爱思唯尔有限公司保留所有权利。
This study evaluated the feasibility of methane production from fruit and vegetable waste (FVW) obtained from the central food distribution market in Mexico City using an anaerobic digestion (AD) process. Batch systems showed that pH control and nitrogen addition had significant effects on biogas production, methane yield, and volatile solids (VS) removal from the FVW (0.42 m(biogas)(3)/kg VS, 50%, and 80%, respectively). Co-digestion of the FVW with meat residues (MR) enhanced the process performance and was also evaluated in a 30 L AD system. When the system reached stable operation, its methane yield was 0.25 (m(3)/kg TS), and the removal of the organic matter measured as the total chemical demand (tCOD) was 65%. The microbial population (general Bacteria and Archaea) in the 30 L system was also determined and characterized and was closely correlated with its potential function in the AD system.
