Problems solved by technology

Residues of antibiotics, growth hormones and other drugs in pig feed have significantly reduced the quality and taste of pork, and cannot meet people's requirements for dietary health
In the prior art CN103224454A "a separation and extraction process of glutamic acid", the bacterial protein was used to prepare feed, but the bacterial protein was not separated from the feed product for processing, the digestion and absorption effect was not good, and the disease resistance was insufficient; Moreover, a large amount of mother liquor is produced and needs to be discharged, and the purpose of energy saving and emission reduction has not been achieved.

Embodiment 1

[0032] A method for treating high-concentration glutamic acid waste liquid, comprising the steps of:

[0033] Step 1) Filtration of fermentation broth: the glutamic acid fermentation broth is sterilized by microfiltration membrane filtration, and the retentate and filtrate are collected respectively; The retentate and concentrated liquid are combined into feed liquid A for later use; among them, the microfiltration membrane is an inorganic ceramic membrane with a molecular weight cut-off of 2000MW and a microfiltration temperature of 40°C; the ultrafiltration membrane has a molecular weight cut-off of 300MW and an ultrafiltration temperature of 40°C;

[0034] Step 2) Decolorization, concentration and crystallization: Step 1) The obtained permeate is pumped into the decolorization tank for decolorization treatment, adding activated carbon accounting for 1% of the permeate mass in the decolorization tank, controlling the temperature in the decolorization tank to 45°C, and after d...

Embodiment 2

[0046] A method for treating high-concentration glutamic acid waste liquid, comprising the steps of:

[0047] Step 1) Filtration of fermentation broth: the glutamic acid fermentation broth is sterilized by microfiltration membrane filtration, and the retentate and filtrate are collected respectively; The retentate and concentrated liquid are combined into feed liquid A for later use; among them, the microfiltration membrane is an inorganic ceramic membrane with a molecular weight cut-off of 2000MW and a microfiltration temperature of 40°C; the ultrafiltration membrane has a molecular weight cut-off of 300MW and an ultrafiltration temperature of 40°C;

[0048] Step 2) Decolorization, concentration and crystallization: Step 1) The obtained permeate is pumped into the decolorization tank for decolorization treatment, adding activated carbon accounting for 2% of the permeate mass in the decolorization tank, controlling the temperature in the decolorization tank to 45°C, and after d...

Embodiment 3

[0060] Feed effect test prepared by the present invention:

[0061] 1. Select 120 swine fever-infected pigs, aged between 2 and 5 months; the symptoms are: unknown high fever, loss of appetite or disappearance, conjunctivitis with purulent secretions, and purulent mucus often flow out of the nasal cavity , with vomiting and blood in the stool; there are often many spot-like bleeding or large red spots on the skin of the base of the ear, abdomen, and medial thigh. Mesenteric lymph nodes are swollen, often with hemorrhagic enteritis, and button ulcers in the mucosa of the large intestine. They were randomly divided into three groups, 40 in each group; all three groups were treated with Qingwenbaidu powder, 20g per 1kg of body weight, for 7 consecutive days.

[0062] Experimental group: given the feed prepared in Example 1 of the present invention; Control group 1: given Tongwei medium and large pig compound feed; Control group 2: the feed prepared according to Example 1, but wi...

Abstract

The invention belongs to the field of the disposal of amino acid fermented waste liquid, and discloses a method for disposing the high-concentration waste liquid of glutamic acid. The method comprises the following steps: (1) filtering the waste liquid; (2) decolouring, concentrating and crystallizing the filtered waste liquid; (3) hydrolyzing the crystallized waste liquid; (4) preparing composite medicinal powder; (5) preparing main materials; (6) preparing a feed. The method is simple and feasible, the energy is saved, the emission is reduced, and the waste liquid is used for preparing the feed, so that enormous economic benefits are brought for enterprises.

Description

[0001] technical field [0002] The invention belongs to the field of amino acid fermentation waste liquid treatment, and in particular relates to a method for treating high-concentration glutamic acid waste liquid. [0003] Background technique [0004] With economic development and technological progress, my country has become a big country in the production and demand of monosodium glutamate, and the fermentation liquid in the production process of monosodium glutamate will produce a large amount of high-concentration waste liquid after isoelectric and ion extraction, and the waste liquid is rich in amino acids, bacteria Body, protein and other solid matter suspensions, various inorganic salts, organic acids, biotin and reducing sugars, etc., have the characteristics of "five highs and one low", namely COD, BOD, COD, Cl + SO 4 , NH 3 -N, high bacteria content, low pH, difficult to handle, is one of the biggest sources of pollution in glutamic acid production. At presen...
