摘要
沼液中营养元素回收和高附加值利用技术是沼液处理与资源化利用研究的新方向。近年来,如何高效回收利用沼液中的氮,同时降低沼液后处理难度,是研究的热点和难点。对不同发酵原料所产生沼液的理化特性和沼液中氮回收利用技术的应用效果进行了综述,阐述了沼液中氮的回收利用技术的研究重点及发展方向,以期为沼液处理与资源化利用提供技术支撑。
Nutrient recycling and high\|value utilization of biogas slurry are innovations in resource utilization of biogas slurry.In recent years,the technology of efficient nitrogen recycling from biogas slurry and reuse as a popular and difficult spot is widely concerned,for its advantage in reducing difficulties of the further biogas slurry treatment.The physicochemical characteristics,and nitrogen recycling and reuse technologies of various biogas slurry were summarized,which indicating the direction of development and providing the technical support.
