| 摘 要： | 畜禽粪便属于有机物含量高、卫生风险大的污染物.本研究探寻不同热处理时间下,猪粪(含固率27.6%)不稀释直接进行70℃热处理的情况及热处理对中温高固厌氧消化的影响.结果表明,热处理能够去除猪粪的部分有机物,并能明显提高高固厌氧消化的产甲烷能力和产甲烷速率.热处理时间为1、2、3和4 d时,热处理对猪粪的VS去除率分别为15.1%、15.5%、17.8%、20.0%,甲烷产率(以CH4/VSadd计)分别为284.4、296.3、309.2、264.4 m L·g-1,相比原粪的甲烷产率分别提高49.7%、55.9%、62.7%、39.2%.热处理时间为3 d时,猪粪的甲烷产率最高.热处理对猪粪产甲烷的促进效果显著,能耗适中,并能够起到巴氏消毒的作用,具有较好的工程价值.
