摘　　要：有机废弃物沼渣作为厌氧堆肥发酵的残留物,富含植物生长所需的氮、磷、钾等大量元素以及铜、铁、锰、锌等中、微量元素,将其资源化利用可以减少对环境的污染,对创建资源节约型、环境友好型社会具有重要意义。文章在总结前人研究的基础上阐述了沼渣的特性、资源化利用途径,梳理资源化利用过程中存在的问题,并提出相应对策。As a residue of anaerobic compost fermentation,biogas residue is rich in nitrogen,phosphorus,potassium,and other signicant elements required for plant growth.As well as medium and trace elements such as copper,iron,manganese,and zinc,and its resource utilization can reduce the environmental impact pollution which is of great significance for creating a resource-saving and environment-friendly society.Based on summarizing previous research,the article expounds on the characteristics of biogas residue,the way of resource utilization,sorts out the problems existing,and proposes countermeasures.
