Embodiment 1
[0027] The method for preparing fertilizer by utilizing amino acid production waste liquid, it comprises the steps:
[0028] Step 1) filtering, step 2) hydrolyzing bacterial protein, step 3) preparing fertilizer component A, step 4) preparing fertilizer component B, and step 5) preparing fertilizer.
[0029] Specifically, the method includes the steps of:
[0030] Step 1) Filtration: use microbial fermentation to obtain a fermented liquid, filter the fermented liquid, collect bacterial protein and filtrate, use the filtrate to extract amino acids, and use the waste water generated during the extraction process for standby;
[0031] Step 2) Hydrolyze bacterial protein: Dry the bacterial protein, pulverize it into dry protein powder, then put it in the reaction tank, add 5 mol / L hydrochloric acid of the same quality as the dry protein powder, subject to the raw material being submerged, in the Stir and hydrolyze at 60°C for 24 hours at a stirring speed of 300 rpm. After the rea...
