发酵沼液深度处理与资源化利用技术研究进展

Research Progress on Advanced Treatment and Resource Utilization of Fermentation Biogas Slurry

伴随我国沼气工程的大规模发展,大量沼液面临无法消纳的问题,系统总结了现有沼液深度处理及资源化利用技术,包括生物处理技术、物理化学处理技术、组合工艺处理技术和无机组分资源化技术。此外,展望了可能的有机组分资源化技术,以期为沼液同时满足达标排放要求并实现资源化利用提供新思路。

With the large-scale development of biogas projects in China,a large amount of biogas slurry cannot be absorptive.The existing advanced treatment and resource utilization technologies of biogas slurry are summarized systematically,including biological treatment technology,physical&chemical treatment technology and combined technology as well as resource recovery technologies of inorganic components.Moreover,the possible resource recovery technologies of organic component are overlooked in order to provide new routes for the biogas slurry not only to meet the discharge requirements but also to realize the resource utilization.
