The essence of the two phase anaerobic biological treatment process is to place acid bacteria and methane-producing bacteria in two reactors respectively, where it can provide the optimal conditions for their growth and metabolism, allowing them to live up to their maximal activity, which greatly improve processing capacity and efficiency compared to a single-phase anaerobic digestion. The paper start with the two phase anaerobic digestion process, in order to discuss the development direction of high efficient anaerobic digestion system.
