Anaerobic digestion of dairy cow manure (CM), the organic fraction of municipal solid waste (OFMSW), and cotton gin waste (CGW) was investigated with a two-phase pilot-scale anaerobic digestion (AD) system. The OFMSW and CM were digested as single wastes and as combined wastes. The single waste digestion of CM resulted in 62m3 methane/ton of CM on dry weight basis. The single waste digestion of OFMSW produced 37m3 methane/ton of dry waste. Co-digestion of OFMSW and CM resulted in 172m3 methane/ton of dry waste. Co-digestion of CGW and CM produced 87m3 methane/ton of dry waste. Comparing the single waste digestions with co-digestion of combined wastes, it was shown that co-digestion resulted in higher methane gas yields. In addition, co-digestion of OFMSW and CM promotes synergistic effects resulting in higher mass conversion and lower weight and volume of digested residual.
采用两相中试规模厌氧消化（AD）系统，对奶牛粪便（CM）、城市生活垃圾有机组分（OFMSW）和轧棉废料（CGW）的厌氧消化进行了研究。OFMSW和CM分别作为单一废物以及混合废物进行消化。CM单一废物消化产生的甲烷量为62立方米/吨（基于干重）。OFMSW单一废物消化产生的甲烷量为37立方米/吨干废物。OFMSW和CM共消化产生的甲烷量为172立方米/吨干废物。CGW和CM共消化产生的甲烷量为87立方米/吨干废物。将单一废物消化与混合废物共消化进行比较，结果表明共消化产生的甲烷气体产量更高。此外，OFMSW和CM共消化促进了协同效应，从而实现更高的质量转化率，并降低了消化残余物的重量和体积。
