| 摘 要： | 以厨余垃圾和废纸为原料，考察了不同原料比例和酸化阶段pH对消化稳定性及产甲烷性能的影响. 结果表明，原料比例为厨余垃圾/废纸100:0的厌氧消化由于挥发性脂肪酸抑制不能形成稳定的产甲烷过程. 原料比例83:17时，酸化阶段pH为6.5, 7.2和7.9的3组厌氧消化甲烷产率(以挥发性固体计)分别为313, 346和360 mL/g，COD去除率为86.3%, 93.2%和95.2%，甲烷含量稳定在70%~80%. 原料比例62:38、pH为6.5, 7.2和7.9的3组厌氧消化甲烷产率分别为97, 247和279 mL/g，COD去除率为32.6%, 80.5%和86.8%，甲烷含量稳定在60%~80%.

| Abstract: | Using kitchen waste and waste paper as anaerobic co-digestion material, the influences of feedstock proportion(ratio of kitchen waste to waste paper at 100:0, 83:17 and 62:38, calculated by volatile solid) and pH value adjustment(6.5, 7.2 and 7.9) in the acidification stage on anaerobic digestion stability and performance was investigated.Experimental results showed that the proportion of 100:0 can not realize stable methane production due to the inhibition of volatile fatty acids.For the proportion of 83:1... |
