摘要
阐述了我国农业废弃物主要利用模式,分析了我国沼气利用现状,结果表明,2000—2015年我国的沼气生产主要以农业废弃物沼气为主,主要包括户用沼气和农业工程沼气,工业工程沼气在我国沼气产业中的比重极低.介绍了与沼气生产结合的循环农业利用模式,包括户用模式(包括"三合一"模式、"四位一体"模式和"五配套"模式)和大中型工程模式,其中大中型工程模式着重介绍了"德青源模式".最后分析了我国农业废弃物沼气化利用中存在的问题,包括农业废弃物资源量巨大,但资源浪费严重;沼气池废弃率高;农业废弃物利用模式多样化,但产业化水平低;农业废弃物处理的相关政策亟待完善;低碳循环农业发展模式的重视程度还不够.
Abstract
The main mode of utilization of agricultural wastes in China was expouded,present situation of biogas utilization in China was ana-lyzed,the results showed that biogas production was mainly based on agricultural waste biogas during 2000-2015,mainly including household bio-gas and agricultural engineering biogas.The proportion of industrial engineering biogas in China's biogas industry was very low.The mode of agri-cultural recycling combined with biogas production was introduced,including household models ( including the "three in one"mode,"four in one"mode and"five matching"mode) and large and medium-sized engineering mode,and the large and medium-sized engineering model mainly was introduced "DQY mode".Finally,the existing in the utilization of agricultural wastes in China biogas production problems were analyzed,in-cluding agricultural wastes in China was huge,but waste of resources was serious;the waste rate of methane tank was high;the mode of agricultural waste utilization was diversified,but the industrialization level was low;the relevant policies of agricultural waste disposal in China should be im-proved urgently;low carbon recycling agriculture development model in China was not enough attention.
