The method has a simple manufacturing technology, saves the investment cost, and is beneficial to popularization and application in agricultural production.
Description
Technical field
The invention belongs to the organic fertilizer production field, specifically relate to a kind of organic fertilizer that utilizes the production of monosodium glutamate industrial waste and preparation method thereof (based on organic fertilizer and the preparation method of demineralised liquid, mud and humic acids).
Background technology
Mud does not generally contain toxic substance, effluxes and causes secondary pollution, processes and brings higher expense, is applicable to do the raw material of organic fertilizer.The a large amount of waste liquids that produce in the glutamate production process utilize conventional process very difficult, have not only increased processing costs, but also have caused great pressure for the environmental protection of enterprise.Humic acids is the larger molecular organics matter that extensively exists, and its basic structure is aromatic ring and alicyclic ring, is connected with the functional groups such as carboxyl, hydroxyl, carbonyl on the ring; Itself and metal ion have the effects such as exchange, absorption, complexing, chelating; In dispersion system, as polyelectrolyte, the effects such as cohesion, peptization, dispersion are arranged.Also have the free radical of some amount on the humic acids molecule, have physiologically active.Humic acids can effectively promote the crop root growth, improves its physiologically active, improves the ability of its Absorption of nourishment material, strengthens fertilizer efficiency.The component of effluent that glutamate production produces is take ammonium sulfate as main, and contains the organic nutrient such as tens seed amino acids, is a kind of good manure resources.Waste liquid remaining demineralised liquid after extracting ammonium sulfate (as inorganic fertilizer) still contains small part ammonium sulfate, because the Organic substances such as amino acid wherein increase, can consider to utilize demineralised liquid to produce fertilizer.For fermentation waste water, the direct intractability of traditional biochemical method is very large, in only being suitable for, low concentration wastewater, and this type of construction investment is large, and working cost is high, and floor space is large, energy consumption is high, not only increase the production cost of enterprise, can not solve thoroughly the blowdown problem.And the method that adopts spray granulating utilizes waste liquid to produce Chemical Mixed Fertilizer, and not only energy consumption is high, and produces a large amount of waste gas in the production process, and atmosphere pollution is unfavorable for environmental protection.And the Chemical Mixed Fertilizer pH that utilizes spray granulating to utilize waste liquid to produce is lower, generally all is lower than 5.5, and this Chemical Mixed Fertilizer of life-time service can cause Soil degradation, affects crop yield.
Summary of the invention
For the deficiencies in the prior art, the purpose of this invention is to provide a kind of organic fertilizer that utilizes the production of monosodium glutamate demineralised liquid and preparation method thereof.The present invention mainly is the difficult problem of utilizing that solves demineralised liquid, produces qualified fertilizer, and solves conventional Chemical Mixed Fertilizer PH low and highly energy-consuming and the sludge disposal problem of producing.
Mud is the microorganism that produces during fermentation, food service industry wastewater biochemical are processed and the compounding substances of suspended substance, and organic content is about 24%, does not generally contain toxic substance, effluxes and causes secondary pollution, processes and brings higher expense, is applicable to do the raw material of organic fertilizer.
Technical scheme of the present invention is as follows:
Based on the organic fertilizer of monosodium glutamate demineralised liquid, be to be prepared from by following raw materials according, be weight part: demineralised liquid 60-80, mud 20-40, humic acids 10-20(is preferred, demineralised liquid 65-75, mud 25-35, humic acids 12-18).
Foregoing organic fertilizer, preferred scheme are, are to be prepared from by following raw materials according, are weight part: demineralised liquid 65, mud 20, humic acids 15.
Foregoing organic fertilizer, preferred scheme is that described demineralised liquid is the L-glutamic acid demineralised liquid.
Foregoing organic fertilizer, preferred scheme are, the compounding substances of described mud for producing in fermentation, the processing of food service industry wastewater biochemical.
Foregoing organic fertilizer, preferred scheme is, first mud and humic acids is mixed, and under stirring, adds mud and humic acids mixture in demineralised liquid, and demineralised liquid and mud, humic acids mixture are mixed, and gets the suspension organic fertilizer.
Foregoing organic fertilizer, preferred scheme is that the mixing speed during stirring is 5rpm.A kind of preparation method of the organic fertilizer based on the monosodium glutamate demineralised liquid comprises the steps: that the mud that will produce in the biological process collects for subsequent usely, gets material 1; Material 1 and humic acids are mixed to get material 2, demineralised liquid is added materials 2 in agitation, demineralised liquid and material 2 are mixed, get suspension.
The present invention is based on the preparation method of the organic fertilizer of monosodium glutamate demineralised liquid, the batch mixing ratio should strictly be followed, and can not at will change, otherwise just can not reach ideal effect.Mud is adjusted the pH of demineralised liquid, and the ammonia that discharges of partial over-alkali is absorbed by mud simultaneously, just can reach the purpose of not losing the nitrogen nutrient.If demineralised liquid is directly mixed with mud and humic acids, will form larger lumpy material, spike is inhomogeneous, does not reach the purpose of adjusting pH and fertilizer homogeneous chemical composition.
In the present invention, raw materials usedly be conventional materials, raw material is easy to get.Used demineralised liquid is the after treatment demineralised liquid of gained of the waste liquid that produces in the glutamate production process, preferred L-glutamic acid demineralised liquid.Used mud is the mud in the gourmet powder waste water biochemical treatment process, can be fast and the acidic substance generation neutralization reaction in the demineralised liquid, be mainly used to regulate the pH of demineralised liquid, and also can increase the organic content of fertilizer.The quality standard of used humic acids: organic content is not less than 60%.Technical solution of the present invention compared with prior art has following outstanding technique effect:
1, the preparation method who the present invention is based on the organic fertilizer of monosodium glutamate demineralised liquid has solved environmental pollution and energy dissipation problem that the produced in conventional processes Chemical Mixed Fertilizer brings: the present invention produces liquid organic fertilizer need not dry, the energy that consumes reduces greatly, the organic substance of demineralised liquid is survivable simultaneously, is down to minimum to the pollution of atmosphere.
2, can give full play to the resource value of demineralised liquid and mud: the fertilizer that the present invention produces, the nutritive substance in the demineralised liquid remains unchanged substantially, and free aminoacid content is high, can fully be absorbed by crop.
3, organic fertilizer synergy of the present invention is obvious, can effectively improve soil, promotes plant growth, improve agricultural product quality.
Embodiment
