Method for photo-fermentation hydrogen and methane co-production from tobacco waste

Abstract

The present invention provides a method for photofermentation hydrogen and methane co—production from tobacco waste, which. belongs to the technical field. of biological hydrogen production and biological methane production. The method provided by the present invention includes: mixing harmful tobacco waste with a buffer solution and a hydrogen—producing culture medium to obtain a first mixture; adjusting a pH value of the first mixture to neutral, and mixing the first mixture with cellulase and HAU—Ml photosynthetic bacterial population liquid in a logarithmic growth phase to obtain a second mixture; performing' photo—fermentation. hydrogen. production. on the second mixture to obtain hydrogen and fermentation tailings; mixing the fermentation tailings with activated sludge to obtain a third mixture; and fermenting the third mixture to produce methane.
