大型沼气发电综合利用工程效益评价研究

Benefits Evaluation of Large-Scale Biogas Power Generation Comprehensive Utilization Projects

指出大型沼气发电综合利用工程不仅能够解决其畜禽养殖场粪便处理问题,发电及余热回收利用可使能源利用效率最大化,还可形成种植、养殖良性循环的经济体系,从而达到污染治理、能源回收与资源再生综合利用的目的。阐述了大型沼气发电综合利用工程经济、社会、环境效益三个方面的评价指标。介绍了物元可拓模型的基本概念,描述了某牧场大型沼气发电综合利用工程的经济指标评价。

Large-scale biogas power generation comprehensive utilization projects can not only provide solutions to livestock and poultry excrement disposal, power generation and waste heat recycling, so as to maximize the energy utilization efficiency; but also can form the benign cyclic economic system of planting and breeding, so as to achieve the purposes of pollution control, energy recovery and comprehensive utilization of renewable resources. This paper elaborates its evaluation index in terms of economy, society and environment benefit. Then the fundamentals of matterelement and extension model are introduced, and the economic index evaluation of a large-scale biogas power genera- tion comprehensive utilization project in a farm is described.
