Embodiment 1

[0024] A method for preparing a compound fertilizer comprising amino acid fermentation waste liquid, comprising the steps of:

[0025] 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;

[0026] 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;

[0027] 3) Cultivate Trichoderma chrysogreen, Pseudomonas aeruginosa, and Candida to a concentration of 1×10 7 bacterium solution per ...

Embodiment 2

[0033] A method for preparing a compound fertilizer comprising amino acid fermentation waste liquid, comprising the steps of:

[0034] 1) Filtrate the amino acid fermentation waste liquid produced by the biological fermentation of amino acids, and collect bacterial protein and waste water;

[0035]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;

Abstract

The invention belongs to the field of waste preparation and discloses a preparation method of a compound fertilizer containing amino acid fermentation waste liquid. The preparation method comprises the following steps of 1 waste liquid filtration, 2 hydrolysis, 3 preparation of a compound fungicide A, 4 preparation of a compound fungicide B, 5 preparation of a fermentation liquor A, 6 preparation of a fermentation liquor B and 7 freeze drying. The fertilizer prepared by means of the preparation method has the advantages of being lasting in fertilizer efficiency, environmentally friendly and free of pollution, having a certain weeding function and the like.

Description

technical field [0001] The invention belongs to the field of fertilizer preparation, and in particular relates to a method for preparing compound fertilizer containing amino acid fermentation waste liquid. 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 produced by fermentation has imp...
