摘　　要：案例分析能源生态型沼气工程、能源环保型沼气工程和发酵床技术的工艺类型,比较3种工程的经济效益、技术效益和环境效益。沼气工程前期投资大,但大型能源生态型沼气工程可以通过丰富再生能源获得收益,能源环保型沼气工程相对于能源生态型沼气工程投资大、收益小,发酵床技术可以实现畜禽粪便"零排放",但菌剂费用造成高额运行费用。建议加强大型生态型沼气工程发展,增强发酵床菌剂的研究以降低发酵床运行成本,推动有机肥市场的有效运行。The process types of energy ecological biogas project,energy environmental protection biogas project and fermentation bed were analyzed with cases.The economic benefit,technical feedback and environmental benefits of three projects were compared.The investment of biogas project was big,but large-scale energy ecological biogas project can earn profit through renewable sources of energy,the energy environmental protection biogas project had more investment and less benefit than ecological one.Fermentation bed can realize ＂zero release＂,but cost on fungicides make high operating cost.It was suggested that strengthen the engineering development of large-scale energy ecological biogas project,enhance the studying of fungicides in order to reduce operating cost of fermentation bed and push forward the marketable of organic fertilizer.
