Abstract

This invention relates to a water-soluble fertilizer containing amino acid produced with glutamic acid mother liquid including: concentrating glutamic acid mother liquid then adding ZnSO4, borax, Mn(SO4)2 and Fe(SO4)2 into the solution to get the fertilizer to be put into bags separately for use, which either avoids waste of glutamic acid mother liquid resource in the production of monosodium glutamate or overcomes pollution to environment.

Description

That utilizes glutamic acid mother liquor production contains the amino acid water-soluble fertilizer

One, technical field

The present invention relates to fertilizer field, particularly a kind of utilize glutamic acid mother liquor production contain the amino acid water-soluble fertilizer.

Two, background technology

Glutamic acid mother liquor is the product that must have in the glutamate production, monosodium glutamate is owing to be to produce by microbial fermentation, contain a large amount of organism (residual sugars in the glutamic acid mother liquor (organic waste water) that produces when it is produced, fat, protein), the available inorganic nutrients thing of amino acid and crop, if discharging arbitrarily, not only wasted ample resources, but also can cause pollution to environment, glutamic acid mother liquor is because the concentration height, general biological method is difficult to handle, if the dilution aftertreatment, expense is too high, how to handle at present with methods such as liquid fertilizers, and the liquid fertilizer treatment process, because of the liquid fertilizer nutrient content is low, volume is big, cause and use and transport, store extremely inconvenient, particularly the seasonal fertilising of agricultural is difficult to solve with the contradiction of industrial continuous production, also more difficultly makes liquid fertilizer become commodity, certainly will strengthen enterprise's pollution treatment expense.At present, produce according to standard GB 17419-1998 tissue " the containing the amino acid water-soluble fertilizer " of circulating on the market, and the key technical indexes is: amino acid 〉=100g/L, and trace element 〉=20g/L, production technique is:

Animal hair → acidification hydrolization → separation → oven dry → preparation → packing, not only complex process, and cost height is with the liquid fertilizer dry solidification, take to do mixed granulation and produce multiple fertilizer, because middle-chain is many, the processing charges height, topsoil is serious, be difficult to effectively apply, therefore, the effective processing and the utilization of glutamic acid mother liquor are to need the technical barrier that solves in the glutamate production always.

Three, summary of the invention

At above-mentioned situation, the present invention's purpose just provide a kind of utilize glutamic acid mother liquor production contain the amino acid water-soluble fertilizer, can effectively solve the utilization again and the cheap problem of producing plant of glutamic acid mother liquor in the glutamate production with fertilizer, the technical scheme of its solution is, glutamic acid mother liquor is concentrated allotment, make solid content by 16%, it is 40-45% that degree Beaume 12 is concentrated into solid content, the glutamic acid mother liquor concentrated solution of degree Beaume 25-28, add zinc sulfate in the glutamic acid mother liquor concentrated solution after concentrating again, borax, manganous sulfate and ferrous sulfate, its component is by weight percentage: glutamic acid mother liquor concentrated solution 82-87%, zinc sulfate 4-6%, borax 4-6%, manganous sulfate 1.5-3.0% and ferrous sulfate 2.5-4%, be mixed evenly, contain the amino acid water-soluble fertilizer, be sub-packed in the bag standby, product cost of the present invention is low, method is simple, glutamic acid mother liquor can be fully used and handle, both efficiently solved the waste of glutamic acid mother liquor resource in the glutamate production, but also solved pollution on the environment, both environmental protection, utilization of waste material again, economic and social benefit is huge.

Four, embodiment

Below in conjunction with embodiment and particular case the specific embodiment of the present invention is elaborated.

Example 1, fertilizer of the present invention are in actual production, adopt by weight percentage: glutamic acid mother liquor concentrated solution 82.5%, zinc sulfate 6.0%, borax 4.5%, manganous sulfate 3.0% and ferrous sulfate 4% mix to be made, wherein the glutamic acid mother liquor concentrated solution be by solid content be 16%, degree Beaume be 12 glutamic acid mother liquor through negative pressure be concentrated into that solid content is 40%, degree Beaume is 25 glutamic acid mother liquor concentrated solution.

Said negative pressure concentrates the triple effect negative pressure evaporation equipment that is meant the employing routine part moisture evaporation in the glutamic acid mother liquor is gone out, and effectively guarantees the mother liquor quality (as follows) after transpiring moisture concentrates.

Example 2, fertilizer of the present invention also can adopt by weight percentage: glutamic acid mother liquor concentrated solution 85%, zinc sulfate 5%, borax 5%, manganous sulfate 2% and ferrous sulfate 3% mixing are made, wherein glutamic acid mother liquor concentrate be by solid content be 16%, degree Beaume be 12 glutamic acid mother liquor through negative pressure be condensed into that solid content is 45%, degree Beaume is 26 glutamic acid mother liquor concentrated solution.

Example 3, fertilizer of the present invention also can adopt by weight percentage: glutamic acid mother liquor concentrated solution 87%, zinc sulfate 4%, borax 4%, manganous sulfate 1.5% and ferrous sulfate 3.5% mixing are made, and wherein the glutamic acid mother liquor concentrated solution is that to be 12 glutamic acid mother liquor through negative pressure be condensed into that solid content is 45%, the glutamic acid mother liquor concentrated solution of degree Beaume 28 by solid content 16%, degree Beaume.

Fertilizer of the present invention after measured, meets state-set standard fully, and wherein many indexs are better than national regulation, and particular case sees the following form 1:

Show by above-mentioned situation, succeeding in developing of fertilizer of the present invention, efficiently solve a large amount of waste liquids that produced in the glutamate production process, be the utilization and the handling problem of glutamic acid mother liquor, comprise during overcoming original " containing the amino acid water-soluble fertilizer " produces and utilize complicated technological process such as animal hair, acidification hydrolization, separation, oven dry, cost is low, overcome in producing pollution to environment, starting material are fully used, refuse has obtained effective processing, having obtained does not have the excellent effect of expecting, through the experiment contrast, has obtained huge benefit:

1, adopt the present invention not only can reduce the pollution of fermentation waste water to environment, resource is fully used, save processing costs, method with the employing waste water treatment is an example, monosodium glutamate per ton is shared the expenses equally 400 yuan, "Lotus" gourmet powder is produced 200000 tons per year, all adopts the technology of the present invention, but 8,000 ten thousand yuan of conserve water processing costss;

2, every production contains the amino acid water-soluble fertilizer for one ton can increase by 1000 yuan of economic benefits, produces 20000 tons per year and contains the amino acid water-soluble fertilizer, can increase by 2,000 ten thousand yuan of economic benefits.If in the same way, it is immeasurable can producing economic worth;

3, fertilizer of the present invention has outstanding result of use, tests on crops such as peach, pear tree, eggplant through Xiangcheng City, Henan Province bureau of agriculture, and effect is outstanding, and relevant situation is as follows:

Experimental technique: establish control group, spray clear water; Fertilizer group of the present invention adds water and becomes diluting soln for 500 times, sprays plant leaf surface.

Spraying time (1) the flower bud fruit phase, (2) fruit expands the initial stage, and (3) fruit expands mid-term.

Minute: the blade dry matter weight, spray back 20 days mensuration in for the third time.

Output is harvesting time.
