Characteristics of Nanobubbles and Their Application in Anaerobic Digestion of Organic Solid Waste
Based on the current research situation at home and abroad,the basic properties,genera-tion mode of nano-bubbles(NBs)and the mechanism of improving the performance of anaerobic digestion were analyzed.The research progress of NBs in anaerobic digestion of organic solid waste and its application in enhancing the stability of anaerobic digestion,accelerating hydrolysis rate and increasing methane production were reviewed.Further research prospects such as strengthening the research of NBs physicochemical properties of different gases,developing a variety of gas sources,improving detection capabilities,reducing energy con-sumption and cost were put forward.
