NOVELTY - Promoting anaerobic methanation of organic acids by using nanographene comprises adding nano-graphene into the organic acid anaerobic methanation reaction, and the dosage of the nano-graphene is 0.1-2.4 g/l. USE - The method is useful for promoting anaerobic methanation of organic acids by using nanographene. ADVANTAGE - The method improves the removal rate of CODCr, increases methane production, shortens the lag time of the reaction, and maintains the particle shape of the sludge.
