沼液资源化利用现状与新技术展望

Resource Utilization of Biogas Slurry: Current Status and Future Prospects

沼液资源化利用技术分为农林牧渔领域的低成本利用和高附加值的开发利用。目前,技术成熟、方法简单的低成本利用是沼液资源化的主要方式。但近年来,价值成分回收、微生物领域应用、营养物间接利用和理化性质利用等高附加值的新技术提高了沼液应用的安全性,拓宽了沼液的利用途径,因而得到快速发展,并成为沼液资源化利用发展的新方向。

Resource utilization of biogas slurry is divided into two ways： low-cost utilization and high value-added utiliza- tion. At present, low-cost utilization in agrlculture, forestry, animal husbandry and fishery, is the primary method to utilize biogas slurry because of its ripened technology and the simple way of use. In recent years, techniques of high value-added utilization, such as collecting valuable components, application in microbiology, making use of nutrients indirectly, and ex- ploiting its physicochemical properties, have developed rapidly and become a new orientation, for it is improved the safety of biogas slurry and broadened the way of resource utilization.
