生物沼气产业价值链探索与分析

Exploration and analysis of industry value chain for biogas

以当前生物质能行业最具产业化可行性的生物沼气为研究对象,在概述生物沼气技术路线与全产业链经济性状况的基础上,分析提高产业经济收益性的方案,最终采用层次分析法研究沼渣制备有机肥产品的最优途径。研究发现,以农业废弃物为资源,采用厌氧发酵生产沼气和沼渣制备有机-无机复混肥的产业链是当前的最佳选择。

As the research object to the biogas which has the most industrial feasibility and most potentially commercialized in current biomass industry . Based on the panorama of the biogas tech-nical route and the economic status of the industry chain, the paper proceeds to analyze the poten-tial solutions to increase the profitability of the industry, and finally comes up with a premium pos-sible solution to obtain organic fertilizer from biogas residue by adopting the AHP （analytic hierar-chy process）. The study showed that biogas production by anaerobic fermentation and preparation of organic-inorganic compound fertilizer by biogas residue was the most effective and feasible in-dustry chain of the utilization of biogas when using agricultural waste as a resource.
