苏北地区大中型农业废弃物沼气工程比较——以金东台模式和马庄模式为例

Comparison of Large and Medium-Sized Agricultural Waste Biogas Projects in Northern Jiangsu Province A Case Study Between Jindongtai Model and Mazhuang Model

畜禽粪便与农作物秸秆是重要的农业废弃物资源。基于沼气生产的农业废弃物利用是当前农业废弃物最重要的用途。该研究对金东台模式和马庄模式进行了实地调研和比较分析,结果显示:金东台模式主要利用畜禽粪便进行沼气生产,经济、社会和环境等方面的效益显著,但该模式由于对资金、技术和地理位置要求高而推广受限;马庄模式的社会和环境效益显著,经济效益一般,但在当前推动农村集中居住的背景下发展潜力较大。该文的研究结果可以为苏北及周边地区的其他大中型沼气工程的发展提供有价值的参考。

Livestock and poultry manure and crop straw are important agricultural waste resources.Biogas production based on agricultural waste is most important use of current agricultural waste.A field survey and comparative analysis of Jindongtai model and Mazhuang model was conducted.Results showed that Jindongtai model mainly used livestock and poultry manure for biogas production,and its economic,social and environmental benefits were significant.However,this model had high requirements for capital,technology and geographic location and was limited in promotion.Social and environmental benefits of Mazhuang model were significant,but economic benefits were poor.Under dual background of promoting rural centralized living and rural waste disposal,Mazhuang model had strong promotion potential.Results of this paper could provide valuable reference for development of other large and medium-sized biogas projects in northern Jiangsu and surrounding areas.
