NOVELTY - Hydrolytic treatment of liquid waste for bio-fuel alcohol production using biomass raw materials to produce bio-fuel alcohol comprises pre-processing the raw material, culturing microbial cell, saccharifying, fermenting, distilling, and dehydrating.    USE - The method is used for hydrolytically treating liquid waste for bio-fuel alcohol production (claimed).    DETAILED DESCRIPTION - Hydrolytic treatment of liquid waste for bio-fuel alcohol production using biomass raw materials to produce bio-fuel alcohol comprises pre-processing the raw material, culturing microbial cell, saccharifying, fermenting, distilling, and dehydrating. It hydrolytically treats liquid waste for bio-fuel alcohol production using multiple enzyme system cell supernatant generated by microculture and recycling it; the bio-fuel alcohol production can generate 3.5-4 tons liquid waste by consuming every one ton biomass raw material, and the liquid waste is distillated, where the dry matter content in each ton liquid waste is 3-10%, and the main components are protein, nitrogen matter, and it further contains cellulose, lignin, oligose, oligosaccharide, fats, vitamin B, growth factor, organic acid, and ash. The method collects the liquid waste in the hydrolytic treating tank, adds multiple enzyme system cell supernatant generated by microbes to conduct hydrolytic treatment to the liquid waste, and the results after the reaction conducts the solid separation, the solid organic fertilizer is recycled, and one part of the liquid is used as the nitrogen source and the water source of the microbial cell culture, and one part returns to the fermenting process. The method specifically comprises: (a) providing microbe for producing multiple enzyme system cell supernatant selected from saccharomycetes or actinomycetes; (b) providing an enzyme system for producing multiple enzyme system cell supernatant containing one or more of protease, protease, cellulose, xylanase, glucanase, pectinase, isoamylase, isoamylase, and muramidase; (c) providing raw auxiliary materials selected by producing medium of the multiple enzyme system cell supernatant (in parts by weight ): carbon source (3-40 parts), nitrogen source (1-10 parts), nutritive salt (1-5 parts), auxin, water (40-94 parts); (d) producing multiple enzyme system cell supernatant: (i) adding the raw auxiliary materials for producing the multiple enzyme system cell supernatant in a special incubator; the constant volume of the special incubator 30-90% of the incubator volume; (ii) inputting air into the special incubator through an air compressor and a clarification system, and the air volume is 0.1-1.4 L/minute; (iii) inoculating the multiple enzyme system cell liquid after cultivation, and the inoculum size is 5-30%; (iv) the microbe cultivation conditions of the multiple enzyme system cell supernatant are: the temperature is 20-39 degrees C, pH is 3.0-8.5, time is 40-150 hours; and (v) adding the multiple enzyme system cell supernatant ending cultivation and the liquid waste into a processing container for liquid waste hydrolyzing process with a volume ratio of (0.0001-0.1):(1), and treating the liquid waste, where the hydrolyzing treatment conditions comprise: temperature is 30-60 degrees C, pH is 3-7, time is 40-150 hours; (e) shifting the matter materials after the raw material pre-processing process into the cultivation medium for culturing; (f) shifting the liquid waste after the biomass ferments into distillation into the treating container and conducting treatment; (g) separating solids, where the liquid part is shifted to the microbial cell culturing process and recycled as a cultivation medium or shifted to fermenting tank in the fermenting process and recycled; (h) dry crushing solid part and preparing as organic fertilizer and recycled; and (i) the cultivation container used by the multiple enzyme system cell supernatant can be a single container, and also can be multiple containers connected in parallel.
