Embodiment 1

[0022] Embodiment 1: the production method of amino acid plant nutrient solution, specifically comprises steps as follows:

[0023] (1) waste liquid after monosodium glutamate fermentation, after extracting thallus, evaporate and concentrate, obtain ammonium sulfate and concentrate after crystallization and separation;

[0024] (2) First lower the temperature of the concentrate to 52°C, add water to adjust the density to 1500kg / m 3 , filter the residue after dropping to normal temperature;

[0025] (3) First adjust the pH value to 4.7 with CaO to fix most of the sulfate groups, and then adjust the pH value to 5.8 with liquid ammonia. The amino acid plant nutrient solution is obtained.

Embodiment 2

[0026] Embodiment 2: the production method of amino acid plant nutrient solution, specifically comprises steps as follows:

[0027] (1) waste liquid after monosodium glutamate fermentation, after extracting thallus, evaporate and concentrate, obtain ammonium sulfate and concentrate after crystallization and separation;

[0028] (2) First lower the temperature of the concentrate to 46°C, add water to adjust the density to 1000kg / m 3 , filter the residue after dropping to normal temperature;

[0029] (3) First adjust the pH value to 4.2 with CaO to fix most of the sulfate radicals, then adjust the pH value to 5.2 with liquid ammonia to obtain amino acid plant nutrient solution.

Embodiment 3

[0030] Embodiment 3: the production method of amino acid plant nutrient solution, specifically comprise steps as follows:

[0031] (1) waste liquid after monosodium glutamate fermentation, after extracting thallus, evaporate and concentrate, obtain ammonium sulfate and concentrate after crystallization and separation;

[0032] (2) First lower the temperature of the concentrate to 50°C, add water to adjust the density to 1300kg / m 3 , and then filter the residue;

[0033] (3) First use CaO (consumed CaO is about 45.5kg / m 3 fertilizer) to adjust the pH value to 4.5, fix most of the sulfate radicals, and then use liquid ammonia (the amount of liquid ammonia consumed is about 29.4kg / m 3 fertilizer) to adjust the pH value to 5.5 to obtain amino acid plant nutrient solution.

[0034] In order to verify the quality of the amino acid plant nutrient solution, the conclusion that the applicant sent the amino acid plant nutrient solution gained in Example 3 to the Food Quality Supervis...

Abstract

The invention discloses a production method of an amino acid plant nutrient solution. The method comprises the following steps: extracting thalli from the fermentation effluent of MSG (monosodium glutamate) to evaporate and concentrate, and crystallizing to separate and obtain ammonium sulfate and a concentrate; treating the concentrate with CaO and liquid ammonia, fixing sulfate radicals, and adjusting the pH value to obtain the amino acid plant nutrient solution. By adopting the production method, the wastewater treatment problem of the MSG fermentation industry can be solved fundamentally, the wastewater can be converted into the amino acid plant nutrient solution, and the environmental benefit, economic benefit and social benefit are significant.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a production method of amino acid plant nutrient solution. Background technique [0002] The fermentation waste liquid produced during the fermentation process of MSG is the main source of pollution in the MSG production industry. According to calculations, using the isoionization and cross-extraction process, for every 1 ton of monosodium glutamate produced, 10-12 tons of high-concentration waste liquid and about 30 tons of low-concentration waste liquid will be produced; if the fermentation broth concentration and crystallization extraction process is used, for every 1 ton of monosodium glutamate produced, 1 ton of monosodium glutamate will be produced. Produces about 5 tons of high-concentration waste liquid, and does not produce low-concentration waste liquid. It can be seen that MSG waste liquid is one of the main sources of pollution in the light industry because o...
