摘要/Abstract

摘要： 利用6种碳基材料进行餐厨垃圾厌氧消化试验,采用AMPTS全自动甲烷潜力测试系统开展产甲烷潜力试验,结合动力学方程分析餐厨垃圾产甲烷潜力及碳基材料对餐厨垃圾厌氧消化性能的影响。结果表明,除碳布、碳纳米管（物料比为3∶5,m/m,下同）外,添加其他碳基材料均可以提高餐厨垃圾厌氧消化有机物的去除率,提高有机物降解性能。生物炭添加组的累积甲烷产量分别比对照组提高55.9%（物料比为4∶5）和55.5%（物料比为3∶5）;采用修正的Gompertz模型方程对累积甲烷产量进行拟合,在餐厨垃圾厌氧消化中添加生物炭能够明显提升物料产甲烷的能力并缩短厌氧消化滞后期。微生物群落结构分析表明,餐厨垃圾厌氧消化前后的细菌群落结构在门水平未发生较大变化,厚壁菌门和拟杆菌门为各试验组的优势菌门,厚壁菌门具有绝对优势地位;各试验组优势古菌均为甲烷八叠球菌属。

Abstract: Six carbon based materials were used for anaerobic digestion experiment of kitchen waste, and the methane production potential experiment was carried out using the AMPTS fully automatic methane potential testing system. The methane production potential of kitchen waste and the influence of carbon based materials on anaerobic digestion performance of kitchen waste were analyzed by combining kinetic equations. The results showed that, except for carbon cloth and carbon nanotubes （material ratio of 3∶5, m/m, the same below）, the addition of other carbon based materials could improve the removal rate of organic matter in the anaerobic digestion of kitchen waste and enhanced the degradation performance of organic matter. The cumulative methane production of the biochar addition group increased by 55.9% （material ratio of 4∶5） and 55.5% （material ratio of 3∶5） respectively compared to the control group;using the modified Gompertz model equation to fit the cumulative methane production, adding biochar to the kitchen waste anaerobic digestion could significantly enhance the material’s methane production capacity and shorten the anaerobic digestion lag period. Microbial community structure analysis showed that the bacterial community structure before and after anaerobic digestion of kitchen waste did not undergo significant changes at the phylum level. Firmicutes and Bacteroidota were the dominant phyla in each experimental group, with Firmicutes having an absolute dominant position; the dominant archaea in each experimental group were all Methanococcus.

Key words: carbon based materials, kitchen waste, anaerobic digestion, methane production potential, performance
