不同碳基材料对餐厨垃圾厌氧消化性能的影响
The influence of different carbon based materials on the anaerobic digestion performance of kitchen waste
摘要
Abstract
Six carbon based materials were used for anaerobic digestion experiment of kitchen waste,and the methane production po-tential experiment was carried out using the AMPTS fully automatic methane potential testing system.The methane production poten-tial 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 addi-tion 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.Micro-bial 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 Methanococ-cus.关键词
