NOVELTY - A comprehensive treatment process involves pre-processing collected wet vinegar residue by mixing wet vinegar residue and hydrochloric acid (0.5-3%) evenly in mass ratio of 2:5, standing mixture at room temperature and soaking for 24 hours, enriching hydrogenogen from cow dung by adding sodium hydroxide (NaOH) solution (0.3-1 mol/L) to cow dung in mass ratio of 3:5, processing for 1-2 hours at 100 degrees C, adding pre-treated vinegar and enriched hydrogenogen to anaerobic fermentation device, and supplementing 55-80% of sewage from vinegar making factory or tap water.    USE - A comprehensive treatment process.    ADVANTAGE - The method avoids the waste of resource as well as environmental pollution and shortens time for treatment.    DETAILED DESCRIPTION - A comprehensive treatment process involves pre-processing collected wet vinegar residue by mixing wet vinegar residue and hydrochloric acid (0.5-3%) evenly in mass ratio of 2:5, standing mixture at room temperature and soaking for 24 hours, enriching hydrogenogen from cow dung by adding sodium hydroxide (NaOH) solution (0.3-1 mol/L) to cow dung in mass ratio of 3:5, processing for 1-2 hours at 100 degrees C, adding pre-treated vinegar and enriched hydrogenogen to anaerobic fermentation device in mass ratio of 10-25%-10-20%, supplementing 55-80% of sewage from vinegar making factory or tap water, adjusting pH to 5.5-7.5 with hydrochloric acid or sodium hydroxide solution, carrying out anaerobic fermentation at 25-55 degrees C for 24-36 hours, contacting hydrogenogen and vinegar fully for generating hydrogen gas, separating fermentation liquid and residue in fermentation system when reaction stops generating hydrogen gas, fermenting supernate obtained from separation to produce methane using supernate of hydrogen production from vinegar residue as substrate, adding activated sludge as mixing strains in which the volume ratio of substrate to strains is 15-17:3-5, adjusting pH to 7 with 1 mol/L of NaOH, and fermenting at 30-50 degrees C for preparing methane, and centrifuging fermented residue and fermentation liquid, dehydrating, drying and crushing sediments, adjusting contents of nitrogen, phosphorus and potassium according to national organic fertilizer standards and preparing microbial organic fertilizer.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the comprehensive treatment process. (Drawing includes non-English language text).
