| 摘 要： | 在相同接种配比(接种污泥占餐厨垃圾的质量分数为30%)条件下,研究了4种不同来源污泥(压滤污泥、厌氧污泥、曝气污泥和河底淤泥)添加或不添加缓冲剂时对餐厨垃圾厌氧发酵产氢效果的影响.结果发现,在不添加缓冲剂时.4种污泥接种餐厨垃圾厌氧发酵平均产氢量依次为厌氧污泥>河底淤泥>压滤污泥>曝气污泥,接种厌氧污泥的餐厨垃圾平均产氢量最高,达10.11mL(以每克挥发性固体(VS)计,下同);而添加缓冲剂时.4种污泥接种餐厨垃圾厌氧发酵平均产氢量依次为厌氧污泥>曝气污泥>压滤污泥>河底淤泥,接种厌氧污泥的餐厨垃圾平均产氢量也最高,为33.72 mL,且体系pH得以缓冲.

| Abstract: | Series of experiments were conducted to determine the effects of seeding sludge (vermicompost sludge, anaerobic granular sludge, angry pool sludge and river sediments) on hydrogen production from anaerobic fermentation of food waste, with and without adding the buffering mixture (alkaline material, surface active agent and enzymes). Without the buffering additives, the effectiveness order of the seeding sludge was granular sludge>river sediments>vermicompost sludge>angry pool sludge; with the buffering addi... |
