Abstract
The invention belongs to the technical field of environmental protection and relates to a method for improving production of methane from surplus sludge of a wastewater treatment plant. The method comprises the following steps of: (1) thoroughly mixing sludge with ryegrass for fermentation, hydrolysis and acid production; and (2) performing anaerobic fermentation on the mixture obtained in the step (1) to generate methane. The method for prompting the production of methane from surplus sludge of the wastewater treatment plant with energy grass is capable of improving the yield of short chain fatty acids and the yield of methane from sludge at the same time, and also capable of recovering and reutilizing organic matters in the sludge more thoroughly; and pollution of sludge on the environment is reduced.
