【摘要】 采用添加填埋10年的矿化垃圾对餐厨垃圾厌氧发酵产氢过程的影响进行了两批试验。第一批试验主要初步探讨矿化垃圾接种量对餐厨垃圾产氢影响,此批试验结果表明:添加矿化垃圾可以提高餐厨垃圾产氢浓度(由24%提高到30%);第二批试验是研究矿化垃圾和污泥联合作用对餐厨垃圾厌氧发酵产氢的影响,实验结果表明:添加矿化垃圾后餐厨垃圾厌氧产氢的比氢气产率升高,从60mL/gVS提高到102mL/gVS,最大氢气浓度从33%提高到37%。更多还原

【Abstract】 Two groups of tests were carried out to explore the effects of adding aged refuse with a landfilling time of 10 years on the hydrogen production process by anaerobic fermentation of kitchen waste.In the first group of test,impacts of the inoculation quantity of aged refuse on the hydrogen production of kitchen waste were preliminarily studied.It was found that the concentration of hydrogen production of kitchen waste was increased after adding the aged refuse(increased from 24% to 30%);in the second batch test.The second groups of tests were also carried out to analyze the co-effects of aged refuse and municipal sludge on the hydrogen production.It was seen that the specific hydrogen production ratio and the maximum concentration increased from 64mL/gVS to 102mL/gVS,and 33% to 37%,respectively after adding aged refuse,due to the coordination mechanism of aged refuse and municipal sludge.更多还原
