Example Embodiment
[0051] Example 1
[0052] Step 1. Weigh 100kg of production SOD waste residue;
[0053] Step 2. Add 200L of acidic acetone and homogenize, the volume ratio of concentrated hydrochloric acid in the acidic acetone to acetone is 2:100, and the concentration of hydrochloric acid in the concentrated hydrochloric acid is 12mol / L;
[0054] Step 3. Plate and frame filtration to collect the filtrate;
[0055] Step 4. The filter residue repeats steps 2-3 once, the two filtrates are combined, and the filter residue is collected for the production of peptone;
[0056] Step 5. Adjust the pH to neutral with sodium acetate;
[0057] Step 6. Centrifugation in a three-foot centrifuge to collect about 16 kg of sediment;
[0058] Step 7. Dissolve with 80kg 0.1mol / L NaOH solution;
[0059] Step 8. Centrifuge the tube centrifuge to discard the precipitate;
[0060] Step 9. Adjust pH 4.0 with 0.1mol / L hydrochloric acid;
[0061] Step 10. Collect the precipitate by centrifugation;
[0062] Step 11. The finished pro...
