基于经济技术指标分析的农业废弃物厌氧发酵技术评估
Assessment of anaerobic fermentation technology for agricultural waste based on economic and technical indicators
摘要
Abstract
To comprehensively and systematically evaluate the technical feasibility and economic rationality of the anaerobic co-digestion technology for multi-component substrates,this study adopted a techno-economic analysis model and coupled it with dynamic analysis methods that account for the time value of money.The impacts of construction costs,operation and management costs as well as product revenues on the net present value,internal rate of return,and payback period under four scenarios:anaerobic wet fermentation of cow dung,anaerobic dry fermentation of the binary mixture of cow dung and tomato vines,anaerobic dry fermentation of the binary mixture of cow dung and cucumber vines,anaerobic wet fermentation of the multi-material mixture of cow dung,corn stover and vegetable waste.The results showed that:1)All four scenarios are economically feasible for profit generation under the conditions of this study.2)The anaerobic wet fermentation of the multi-component mixture of cow dung,corn stover and vegetable waste achieved the optimal investment benefit,with a 20-year net present value of 20.858 million yuan,an internal rate of return of 36.7％and an investment payback period of only 3.5 years.3)The benchmark discount rate,electricity sales price,power generation efficiency,heat sales price and biogas residue price have significant impacts on the economic benefits of the project,while the economic benefits are less sensitive to the prices of instruments and equipment.In conclusion,this research provides a scientific basis for the efficient resource utilization of agricultural waste and sustainable development in China's agricultural industrial parks,and effectively promote the green,low-carbon transformation and upgrading of the agricultural industry.关键词
