A METHOD FOR IMPROVING THE METHANE PRODUCTION RATE THROUGH ACIDIFICATION PRETREATMENT OF HYDROGEN PRODUCTION OF KITCHEN WASTE AND SLUDGE

摘要

Provided is a method for improving the methane production rate through acidification pretreatment of hydrogen production of kitchen waste and sludge. The method comprises: mixing the kitchen waste after crushing pretreatment with sludge, hydrolyzing the mixed solution formulated with sulfuric acid at 135℃ to obtain the fermentation materials, adding yeast powder to the fermentation materials, inoculating the dark fermentation hydrogen producing bacteria, creating the anaerobic fermenting environment by introducing the high purity nitrogen, processing dark deep acidification pretreatment of hydrogen production fermentation at the constant temperature 37℃, adding methanogenic bacteria and maintaining anaerobic environment at 37℃ to ferment and to produce methane.
