Description
Technical field
The present invention relates to a kind of methods of excrement weathered coal hamlessizing technology organic fertilizer.
Background technique
China reduces the dosage of chemical fertilizer to the economical production that develops eco-agriculture, and improves soil for agricultural production, increases soil
Earth organic matter, a times fertile soil fertility deepen continuously to the research of organic fertilizer, for agricultural production ecology from now on, low-carbon, organise, follow
Ring agricultural economy has established technical support and deposit for grain security.
Weathered coal is a kind of coal of low heat value, and since utility value is low, processing capacity is limited, the weathering largely exploited
Coal is discarded.According to statistics, having exploited discarded weathered coal at present has upper trillion tons, and recovery ecosystem weathered coal leaved for development has up to a hundred
Hundred million tons, the weathered coal utilized every year is less than 50,000 tons.Weathered coal contains the organic matter of 70%-80%, contains 30% in organic matter
The humic acid of left and right has 3%-4% low molecule Huang humic acid in humic acid, and middle molecule palm fibre humic acid 12% or so, macromolecule is black
Humic acid 15% or so.It is used for the organic matter in weathered coal to produce organic fertilizer technique, provides guarantee to improve organic fertilizer quality.
Weathered coal produces the humic acid that organic fertilizer only utilizes wherein 30% mostly in the process, and other 50%-60% organic matters do not obtain
It makes full use of, decomposition of the weathered coal in soil is -50 years 25 years.Macromolecule humic acid is only become to the activity of small molecule
Group could be fully absorbed utilization by plant.
CN 102276300 discloses " a kind of preparation method of the full price organic fertilizer for trickle irrigation ", and organic matter and water are thrown
Entering in reactor, sequentially adds sodium nitrite and sodium pyrosulfite, sulfonating reaction terminates, and it is cooling, nitric acid is added and carries out nitration
Reaction；Reaction mass is placed on water distribution in kneader through dryness in the sun, adds phosphorus pentoxide to carry out kneading and connects skill reaction, adds
Potassium oxide and liquefied ammonia carry out neutralization reaction, control pH value 6.0-8.0, obtain cream solid；It is dry through drying line, then crushed, made
Grain machine disposition is got product；Wherein organic matter is to smash weathered coal, and through selection by winnowing, water sedimentation is obtained.To avoid nitration reaction
Nitrogen oxide object overflows pollution environment, and this method uses wet-treating, the disadvantage is that: 1. will add water in process of production, dry by water
It is dry, when energy charge, increase production technology cost.2. when oxidation is sulphite, increase the salt amount of organic fertilizer, reduces organic
Effective content in fertilizer, reduces quality.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method of excrement weathered coal harmless treatment production organic fertilizer, should
Method can realize stool detection, protect environment, and make full use of waste resource, improve organic fertilizer quality.
The technical scheme is that
A kind of method of excrement weathered coal harmless treatment production organic fertilizer, weighs raw material and is produced, specific to walk
It is rapid as follows:
(1) pretreatment of raw material
In parts by weight, will dehydration excrement or dry manure with 20 parts -50 parts of dry basis and 80 mesh weathered coals with
It 50 parts -80 parts of dry basis, stirs evenly, it is 1 part -2 parts of 50%-98% sulfuric acid that concentration, which is added, is reacted at room temperature
1 part of dimethyl sulfoxide is added in 10min-20min, while it is 2 parts -2.5 parts of 70%-98% nitric acid nitre at room temperature that concentration, which is added,
Glycosylation reaction 10min adds 60%-98% phosphatase 11 part phosphorylation 10min-20min at room temperature, discharging ageing；
(2) it is aged
Material is stacked with a thickness of 1 meter when ageing, and room temperature is aged 48 hours under ultraviolet lamp irradiation condition；
(3) chelatropic reaction
In parts by weight, the material after ageing is filled with 16 part -32 of liquefied ammonia with 100 parts of dry basis while stirring
Part, chelatropic reaction 15min-30min is carried out, then adjust pH value 6-8 with potassium oxide, it is organic to obtain excrement weathered coal harmless treatment
Fertilizer.
Further, when chelatropic reaction, reaction temperature is 90 DEG C -100 DEG C.
Further, it in step (1), according to parts by weight with dry basis, has been dehydrated or dry manure is 50 parts, 80 mesh
Weathered coal is 50 parts.
Further, in step (1) when sulfonation, the sulfuric acid concentration that uses is 98%, and when nitrification, the concentration of nitric acid used is
98%, when phosphorylation, the phosphoric acid concentration used is 98%.
Further, in step (1), in parts by weight, 98% sulfuric acid is 1 part, and 98% nitric acid is 2 parts, 98% phosphorus
Acid is 1 part.
Further, when ultraviolet light irradiation, the ultraviolet lamp power used is 10W.
The beneficial effects of the present invention are:
(1) do not have to plus water, drying hair produce.
(2) dry production organic fertilizer is accordingly to carry out sulfonation, nitrification, phosphatization with nitric acid, sulfuric acid, phosphoric acid, in this process
In there is sulfide and nitrogen oxide to overflow, make absorbent with dimethyl sulfoxide, the sulfide of spilling and nitrogen oxide become into organic fertilizer
In effective substance.
(3) it is irradiated in ageing with ultraviolet radiator, shortens digestion time, accelerated molecule conversion, eliminate bad flora.
(4) without drying, energy consumption is few, reduces the discharge of exhaust gas.
Rational technology, fertilizer nutrient is high, is easy to be absorbed by crops.It is handled using sulfuric acid dry method sulfonation, then uses nitric acid,
Phosphoric acid carries out nitrification and phosphatization, improves the substance content in organic fertilizer, other salt contents is reduced, to improve organic
Fertile quality, then through big nutrient liquefied ammonia (nitrogen) needed for plant, potassium oxide (potassium element) carries out chelatropic reaction and obtains
The organic fertilizer of high-quality.Wherein sulfonation, nitration, the purpose of phosphorylation are by the branched chain molecule polysaccharide in excrement and weathered coal
Molecule wood fibre carries out sulfonation, nitration, and phosphorylation makes the macromolecular complex in raw material be changed into soluble small-molecule substance,
It is easy to be absorbed by plants.Temperature is increased to 90 DEG C -100 DEG C naturally in chelatropic reaction, while by excrement high-temperature sterilizing insecticidal.Excrement
Just its organic matter of the organic fertilizer produced after harmless treatment reaches 50%-70%, N P and K total amount >=7%-30%；Production
Organic fertilizer quality index out is superior to national sector standard.
