摘要：

Anacrobi( co-digcstion ofoittle, manure with NaO144reatod corn stover for biogas production was investigated, Four cattle mail Lire to corn Stover ratios (CM/C,S) a r 1: 1, 1:2,1:3,and 1:4, andthree feeding concentrntions (FQ of50,65, and 80gL-1 wore used. Tile resul ts sho wed that the co-di gesti oil with CM/CS ratio of 1:3 obtained the highest total biogas production of 20.5 L, niethane yield of 194 mL C144 9 1 Vs, and TS and VS reductions of 45.0% and 53.0% at the FC of 65 g L-1. Therefore, the FC of 65 g L-1 and CM/CS ratio of 1:3 was selcaeclas the optimal one, Compared to the single digestion, 4.9-7.4% more biogas productions were obtained at tho sarne FC'of 05 g L-1 due to the synergistic ell'oet. Tile synergistic effccl is mainly attributed to more ball-inced ni,itricrits and increased buffering capacity. It indicated that co-digestion of cattle manurc with NaOlq-trcated corn stover could be one of the options for efficient blogas prgduedon and waste trCatrilent,
