红毛丹果皮沼气发酵试验研究及果皮回收利用分析

目的]获得红毛丹（Nephelium lappaceumL．）果皮沼气发酵的相关参数及条件，探讨其沼气发酵潜力。方法]30℃下，采用全混合批量发酵对红毛丹果皮进行了实验室沼气发酵研究，其中接种物分别为混合接种物及牛粪发酵料液接种物，料液浓度分别为6．15％和6．34％。结果]不同接种物对红毛丹果皮的沼气发酵特性影响较大。综合比较日产气量、总固体（TS）降解率、挥发性固体（VS）降解率、发酵时间等得出，混合接种物对红毛丹果皮的发酵效率更高。就发酵体系中C、N二大营养物质的转化进行了讨论，并就水果果皮的回收利用以实现资源最大化、能源可持续化及环境友好化的沼气工程综合开发利用效益模式进行了概述。结论]该研究可为红毛丹果皮的沼气能源化利用提供科学依据。

Study on the Biogas Fermentation of the Peel of Nephelium lappaceum L. And Its Fruit Peel Recycling Analysis

Objective ] The aim was to obtain the relation parameters and conditions of biogas fermentation of the peel of Nephelium lappaeeum L. , to discuss its biogas fermentation potential. Method] The CSRT anaerobic batch fermentation was used to conduct on the laboratory biogas fermentation research with the fresh peel of Nephelium lappaceum L. as the raw material under 30 ℃, thereinto, two kings of inoeulums were mixed inoculum＇ and cow clung fermentation slurry, and the fermentation liquid concentration were 6.15% and 6.34% respectively. Re- sult ] Different inoeulums had a significant influence on the biogas fermentation properties of the fresh peel of Nephelium lappaceum L.. Com- prehensively considering the daily biogas production, TS degradation rate, VS degradation rate and fermentation time, the mixed inoeulum had a better fermentation efficient on the fresh peel of Nephelium lappaceum L. rather than the cow dung fermentation sludge. Moreover, the two major nutrients C, N transformed in fermentation system was discussed, and summed up the synthetical development and utilization efficient model of environment-friendly biogas engineering that realized the resource maximization and energy sustaining through the recycling of the fruit peel. Conclusion] The study provides a scientific basis for biogas energy use of the peel of Nephelium lappaceum L..
