Problems solved by technology

[0006] Biotechnology treatment of fermentation wastewater has the advantages of low cost and no secondary pollution, but there are unreasonable microbial compatibility, low treatment efficiency, and poor internal mass transfer of microbial carriers, which are not easy to transmit light, small specific surface area, and long service life. Defects such as shortness; biological agents need to be put in more times, which increases the cost, and the amount of dosing is large, resulting in a large amount of sludge, which is not easy to handle

Embodiment 3

[0059] Effect test of the present invention:

[0060] The experiment was carried out by taking the fermentation waste liquid from which substances such as fermentation bacteria, protein and polysaccharides had been removed as the treated sample.

[0061] Control group 1: use diatomaceous earth carrier; the type of microorganisms is the same as the test group; treatment method: after three days of continuous dosing, 5g / m3 per day, and then stand for six days, the detection and treatment results are shown in Table 1.

[0062] Control group 2: The carrier is the same as in Example 2, the difference is that only three kinds of bacteria are added, and Scenedesmus obliques is not added; treatment method: add 5g / cubic meter on the first day, then leave it for six days, and test the treatment The results are shown in Table 1.

[0063] Test group: microbial preparation prepared in Example 2 of the present invention; treatment method: one day after adding, 5g / cubic meter, and then stan...

Description

technical field [0001] The invention belongs to the technical field of amino acid fermentation waste water treatment, and in particular relates to a treatment method for L-arginine fermentation waste liquid. Background technique [0002] Arginine (arginine, Arg) chemical name: 2-amino-5-guanidino-valeric acid, is an aliphatic basic polar α-amino acid containing guanidine group, which is positively charged under physiological conditions; L -Arginine is the encoded amino acid in protein synthesis. For mammals, arginine is classified as a semi-essential or conditionally essential amino acid, depending on the developmental stage and health status of the organism. Natural products exist in large quantities in protamine and are also the basic components of various proteins. [0003] L-arginine is hailed as a "magic molecule" by scientists. It is one of the basic amino acids. For healthy adults, it is a non-essential amino acid, but arginine is an essential amino acid for maintain...
