基于大规模厌氧消化和热电联产技术的甜叶菊废渣综合利用

Comprehensive Utilization of the Stevia Sugar Residue Based on Large Anaerobic Digestion and Cogeneration Technique

甜叶菊提取完甜菊糖后会形成一种植物性的废料有待处理。采用大规模厌氧消化技术处理甜叶菊废渣,同时结合热电联产技术,利用厌氧产生的沼气来发电,发电后的余热用于厌氧反应器的加热和厌氧后废渣的烘干,烘干后的废渣可作为有机肥的基肥原料,从而实现了对废渣的综合利用。

The residue will be produced during the process of the extracting the stevia sugar from stevia rebaudiana. A technique is introduced in the article. We deal with the residue with large anaerobic digestion technique and then the methane will be produced. The methane is used by the gas engine for generating the power to the grid and the heat for heating the anaerobic reactor and the residue of anaerobic treatment. The dry residue is used for making organic fertilizer.
