Embodiment 1
[0025] Pump 20 tons of waste mash protein into the reaction kettle, and then pump 1 ton of waste gulonic acid mother liquor. After stirring, the pH value is 5.0. Heat the reaction kettle to 90°C, keep it warm for 1 hour, and keep it still. Pump out the supernatant in the reactor (about 17 tons), pass through 40 kg of slaked lime Ca(OH) 2 Adjust the pH to 7.2, evaporate and concentrate until the polypeptide and amino acid account for about 9wt%, and then add appropriate amount of trace elements and crop stalks according to the organic fertilizer standard to become the polypeptide organic fertilizer. In this embodiment, the trace elements may be Fe, Zn, Mn, Mo and B, and by weight percentage, Fe 1.2%, Zn 0.8%, Mn 0.2%, Mo 0.1%, B 0.1%. The precipitated part in the reaction kettle is pumped into the plate and frame filter press, and after being filtered, it is dried with a dryer and crushed to make bacterial protein (about 1.5 tons).

Embodiment 2
[0029] Pump 20 tons of waste mash protein into the reaction kettle, and then pump 3 tons of waste azuronic acid mother liquor. After stirring, the pH value is 4.0. Heat the reaction kettle to 50°C, keep it warm for 2 hours, and keep it still. Pump out the supernatant in the reaction kettle (about 18 tons), adjust the pH to 7.2 through 100 kilograms of slaked lime, and concentrate through evaporation to: polypeptides and amino acids account for about 7.6wt%, and then add appropriate amount of trace elements and Crop stalks become polypeptide organic fertilizers. In this embodiment, the trace elements may be Fe, Zn, Mn and B, and by weight percentage, Fe 1.0%, Zn 0.7%, Mn 0.1%, B 0.2%. The precipitated part in the reaction kettle is pumped into the plate and frame filter press, and after being filtered, it is dried with a dryer and crushed to make bacterial protein (about 1.0 tons).

Embodiment 3
[0033]Pump 20 tons of waste mash protein into the reaction kettle, and then pump 2 tons of waste gulong acid mother liquor. After stirring, the pH value is 3.0. Heat the reaction kettle to 40°C, keep it warm for 12 hours, and keep it still. Pump out the supernatant in the reaction kettle (about 15 tons), adjust the pH to 7.2 with 65 kg of slaked lime, and concentrate through evaporation to: peptides and amino acids account for about 10wt%, and then add appropriate amount of trace elements and crops according to the organic fertilizer standard Straw becomes polypeptide organic fertilizer. In this embodiment, the trace elements may be Fe, Mn and B, and by weight percentage, Fe is 1.5%, Mn is 0.7%, and B is 0.3%. The precipitated part in the reaction kettle is pumped into the plate and frame filter press, and after being filtered, it is dried with a dryer and crushed to make bacterial protein (about 1.7 tons).
