中文摘要：

采用联产氢气和甲烷复合工艺,对造纸污泥和餐厨垃圾进行中温-高温混合厌氧消化,通过设计两种物料的不同配比（质量比,以VS计）,研究了不同比例混合的物料联产氢气和甲烷的性能.试验结果表明,造纸污泥和餐厨垃圾混合比例为2：2的反应器总气体产率最高,达496.78mL·g-1（其中,氢气64.48mL·g-1,甲烷432.3mL·g-1,均以VSfed计,下同）,其VS去除率也最高,达41.33%,在反应30h后和产甲烷18d后分别完成了80%的氢气产量和甲烷产量,而单纯造纸污泥总气体产率为144.99mL·g-1,单纯餐厨垃圾总气体产率为80.4mL·g-1.综合氢气和甲烷产率、产气速率、VS去除率等指标发现,造纸污泥和餐厨垃圾混合发酵联产氢气和甲烷的最佳配比为2：2.

英文摘要：

The hydrogen-methane production was investigated through the mesophilic-thermophilic anaerobic co-digestion of paper mill sludge（PS） and food waste（FW） by different mixing ratios of volatile solid（VS） in batch reactors.The results showed that the maximum gas yield was 496.78 mL · g-1 VSfed（64.48 mL · g-1 VSfed of hydrogen yield and 432.3 mL · g-1 VSfed of methane yield） obtained in reactor T3 where the ratio of PS to FW was 2：2 based on VS,and the highest removal efficiency of VS was 41.33% in the reactor.Moreover,80% of hydrogen and methane were produced in the stage of hydrogen fermentation for 30 h and methane fermentation for 18 d,respectively.However,the gas（hydrogen and methane） yield was 144.99 mL · g-1 VSfed for sole FW digestion and 80.4 mL · g-1 VSfed for sole PS digestion.It can be concluded that the best ratio of PS to FW was 2：2 based on VS for hydrogen-methane production through anaerobic co-digestion.
