Efficient multi-dimensional carbon source and preparation method thereof

The invention discloses an efficient multi-dimensional carbon source and a preparation method thereof and relates to the technical field of carbon sources. The efficient multi-dimensional carbon source is prepared from the following components in percentage by weight: 30%-50% of alcohol substances, 20%-30% of biomass digestive juice, 1%-10% of carbohydrates, 0.5% of polymethyl methacrylate and the balance of water. The preparation method of the high-efficiency multi-dimensional carbon source comprises the following steps: 1, measuring raw material formulas with corresponding mass fractions; 2, sequentially adding the biomass digestive juice, the alcohol substance, the carbohydrate, the water and the polymethyl methacrylate into a reactor, and uniformly performing mixing to obtain the efficient multi-dimensional carbon source. By adopting the technical scheme, by-products and wastes of various industries are used as raw materials to produce and compound the efficient multi-dimensional carbon source, so the eff
