Embodiment 1

[0028] The method for producing biological bacterial fertilizer by using amino acid fermentation waste liquid and corn stalks comprises the following steps:

[0029] 1) Filtrate the amino acid fermentation waste liquid produced by biological fermentation of amino acids (use the biological fermentation method to prepare amino acids, collect the residual waste liquid after amino acids, including bacterial protein, sugar, ammonia nitrogen and other substances) to collect bacterial protein and wastewater;

[0030] 2) Dry the bacterial protein, pulverize it into powder, then put it in the reaction tank, add 5mol / L hydrochloric acid, subject to the raw material, stir and hydrolyze at 60°C for 24 hours, the stirring speed is 300 rev / min, neutralize the residual hydrochloric acid with ammonia water after the reaction is terminated, and control the pH of the solution to be 6.8-7.2;

[0031] 3) Crush corn stalks into corn stalk powder, add to the solution in step 2), stir evenly, let st...

Embodiment 2

[0037] The method for producing biological bacterial fertilizer by using amino acid fermentation waste liquid and corn stalks comprises the following steps:

[0038] 1) Filtrate the amino acid fermentation waste liquid produced by the biological fermentation of amino acids, and collect bacterial protein and waste water;

[0039] 2) Dry the bacterial protein, pulverize it into powder, then put it in the reaction tank, add 5mol / L hydrochloric acid, subject to the raw material, stir and hydrolyze at 60°C for 24 hours, the stirring speed is 300 rev / min, neutralize the residual hydrochloric acid with ammonia water after the reaction is terminated, and control the pH of the solution to be 6.8-7.2;

[0040] 3) Crush corn stalks into corn stalk powder, add to the solution in step 2), stir evenly, let stand for 12 hours, then add rapeseed meal, rice husk, shell powder, potassium dihydrogen phosphate, diatomaceous earth and Glucose, stirred at 500 rpm for 3 minutes, then heated to 100°...

Abstract

The invention belongs to the technical field of microorganisms and discloses a method for producing biological bacterial fertilizer from amino acid fermentation liquid waste and corn stalks. The method comprises following steps: step 1), filtering of liquid waste; step 2), hydrolysis and neutralization; step 3), preparation of fermentation broth A; step 4), preparation of fermentation broth B, step 5), uniform mixing and frozen drying. The fermentation liquid waste is applied to fertilizer preparation, so that agricultural waste is utilized, energy is saved, and environment is protected.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a method for producing biological bacterial fertilizer by using amino acid fermentation waste liquid and corn stalks. Background technique [0002] At present, in the process of fermentation and production of various amino acids in biological fermentation enterprises, a large amount of waste liquid is produced, because the fermentation amino acid wastewater contains COD, SO 4 2- and NH 3 -High N content and strong acidity, etc. In addition, the waste liquid also contains a large amount of bacterial protein, reducing sugar, and ammonia nitrogen. If it is discharged indiscriminately, it will not only cause serious environmental pollution, but also waste valuable resources. If the waste liquid is processed, the investment is huge, and it does not meet the requirements of circular economy development. The comprehensive utilization of amino acid waste liquid prod...
