摘　　要：文章以奶酪乳清、牛粪和菌糠为底物,对3种原料进行不同混合配比,研究不同混合比例下厌氧共消化产甲烷性能。试验结果表明:奶酪乳清与牛粪混合比为85∶15时得到最大甲烷产率为313±11 mL·g^(-1 )VS,奶酪乳清的添加会促进牛粪的产甲烷性能,而牛粪的少量添加亦能提高奶酪乳清的产甲烷性能;奶酪乳清与菌糠混合比为15∶85时得到最大甲烷产率为722±16 mL·g^(-1)VS,菌糠的添加能够提高奶酪乳清的产甲烷性能,而奶酪乳清的添加对菌糠厌氧消化有一定的抑制作用;牛粪的少量添加能够促进菌糠的厌氧消化性能,并在混合比15∶85时实现最大甲烷产率为773±16 mL·g^(-1)VS;当3种原料混合共消化时,在奶酪乳清、牛粪和菌糠混合比为10∶10∶80下,实现最大甲烷产率为763±12 mL·g^(-1)VS。In this paper, cheese whey, cow dung and mushroom cultivation residue were mixed in different proportion and used as anaerobic co-digestion substrates, their methane production performance were investigated. The results showed that the cheese whey and cow dung mixing ratio of 85∶15 obtained the maximum methane yield of 313±11 mL·g^-1 VS, the addition of cheese whey could promote methane-producing performance of cow dung, whereas the small amount of cow manure addition could also improve methane-producing performance of cheese whey. The cheese whey and mushroom cultivation residue mixing ratio of 15∶85 had maximum methane yield of 722±16 mL·g^-1VS, the addition of mushroom cultivation residue could improve the methane-producing performance of cheese whey, and the addition of cheese whey could inhibit the anaerobic digestion of mushroom cultivation residue. Small amount of cow manure addition could contribute to improved methane yield of mushroom cultivation residue and realizing the maximum methane production rate of 773±16 mL·g^-1VS at the mixing ratio of 15∶85. When the three raw materials were mixed and digested together, the cheese whey, cow dung and mushroom cultivation residue mixing ratio of 10∶10∶80 obtained the maximum methane production rate of 763±12 mL·g^-1VS.
