The invention relates to a hydrolysis saccharification process of alternanthera philoxeroides. Metal substance pollutants (iron, cobalt and nickel) in alternanthera philoxeroides raw materials are absorbed by adopting magnetic force, so that subsequent mechanical abrasion and contents of metal ions in treating fluid are reduced, and a good fermentation condition is created for detoxification of selected cupriavidus metallidurans; then solid-liquid separation is realized by adopting an extrusion method, hydrolysis on lipids and protein contained in liquid-state materials is carried out by adopting an NaOH solution, and then hydrolysis treatment is further carried out by adopting trypsase, so that the hydrolysis is more completely carried out; meanwhile, extruded solids are dried and crushedand then dropped into a sulfuric acid solution to carry out acidolysis; through electrorheological fluid shear stress effect treatment, cellulase is then added and enzymatic treatment is carried out,so that the effect is good and energy consumption is low. According to the hydrolysis saccharification process of the alternanthera philoxeroides disclosed by the invention, the raw material treatment efficiency is improved to the maximum extent, and finally, saccharified hydrolytic solutions rich in nutrient substances such as glucose, amino acid, small molecule chain lipids and the like are obtained, so that the glucose content is high, and the glucose can be conveniently supplied for further fermentation, and the production efficiency is improved.
