The resource utilization of anaerobic fermentation residue

The popularization of biogas project produced a large number of anaerobic fermentation residues. The resource recycling and harmless utilization of these residues have become one of the hottest researches of related areas. This article summarizes the current situation about researching and utilization of biogas slurry and residues contained their components, functions and status of study domestic and foreign systematically. This study introduces the basic characters of biogas slurry and residues, and systematically summarizes it's newly application and investigation all over the world, and also pointed out the shortcomings. Finally, we forecast the new ways of anaerobic fermentation residues utilization from ecological, environmental and economic points of view.
