摘要
微生物来源对餐厨垃圾厌氧消化产氢的影响很大。单独一种接种物的条件下,剩余污泥的产氢效果是最好的,氢气的浓度和产量都最大,分别为47.1%和100.0 mLH2/g VS,其次是矿化污泥和矿化垃圾,颗粒污泥体系氢气的产量最少,分别为88.6、57.8和36.8 mLH2/g VS,但是颗粒污泥体系产生了甲烷气体。污泥和矿化污泥混合后,在实验时间内,能够提高氢气的产量到106.4 mLH2/g VS,其余的混合体系的氢气的浓度和产量较单独的剩余污泥体系差。
The microorganism source has great impact on hydrogen production by anaerobic digestion of kitchen wastes. Excess sludge is the best in hydrogen production under the condition of a single inoculum, with the highest hydrogen concentration and production of 47.1% and 100.0 mLH2/g VS respectively, the next is mineralized sludge and mineralized wastes, and the worst is granular sludge system, their hydrogen production is 88.6 mLHJg VS, 57.8 mLH：,/g VS and 36.8 mLHJg VS respectively. But the granular sludge system produces methane gas. The hydrogen production can be slightly improved during the experiment to 106.4 mL HJg VS after the sludge is mixed with mineralized sludge, and the hydrogen concentration and production of other mixture systems are less than those of the single excess sludge system.
