Description
Technical field
The invention discloses a kind of method that changing food waste makes degradable anti-caking agent for fertilizer, belong to the field of fertilizer additive.
Background technology
Changing food waste complicated component, because of features such as its high-moisture, high grease, high salinity and perishable smelly, readily biodegradables, unsuitable directly landfill and burning.And its output is large, dispersion, very easily corrupt, foul, pollute urban pavement, air and periphery water system, cause disease, worm, the plague of rats evil raw, have a strong impact on urban environment and HUMAN HEALTH, become the new source of pollution of city environmental pollution.But organic content is abundant compared with other rubbish, fat content is high, there is very large recycling and be worth.Utilize the changing food waste of different chemical component, sterilization is separated by different technique, and then transformed by fermentable, it is made all to become renewable resource and various product, the pollution of changing food waste to environment can be eliminated completely, and provide all kinds of glyceride stock, biological fodder and bio-bacterial manure for industrial or agricultural, promote related industries development, bring huge economic benefit.
Fertilizer caking is the problem, particularly bicarbonate of ammonia that chemical fertilizer industry is devoted to solve for a long time, and ammonium sulfate, ammonium nitrate, ammonium phosphate, urea and composite fertilizer etc. all easily caking phenomenon occur.Fertilizer caking has had a strong impact on fertilizer efficiency, and gives storage, and transport and use bring many difficulties.The bicarbonate of ammonia such as lumpd is easy to bale broken in transit, under the temperature of 26 DEG C ~ 28 DEG C, deposit 10 days, and nitrogen loss can 75.4%.Chemical fertilizer seriously lumps and is difficult to fragmentation, and chemical fertilizer part caking is unfavorable to mechanical fertilization, and the easy betting contest shower nozzle of fritter chemical fertilizer, these are all made troubles to fertilising.Therefore, solving fertilizer caking problem is the important channel of improving chemical fertilizer products quality.Therefore, in order to solve fertilizer caking problem, in the process of chemical fertilizers production, usually anti-caking agent for fertilizer can be used.Market survey finds, anti-caking product category is more, but real Neng Shi composite fertilizer 4 ~ 6 months non-caking anti-hard caking agent products are little.Now widely used domestic its deficiency of anti-caking agent is: part composition is not easily degraded, and life-time service causes soil pollution; Spraying is uneven, reduces result of use; Anti-caking agent discharge rate is excessive, unfavorable to Crop nutrient.
Summary of the invention
The technical problem that the present invention mainly solves: not easily degrade for current anti-caking agent part composition, life-time service causes soil pollution, and length can affect the drawback of fertilizer efficiency duration of service, provide a kind of method that changing food waste makes degradable anti-caking agent for fertilizer, the present invention is first by the leftovers in kitchen, leftovers are separated, first add flyash by filter residue, ramie, the advanced row compost fermentation of the materials such as water, carry out air-dry afterwards, dry, training is fried, put into food steamer again and carry out boiling, put into fermentor tank after boiling to ferment together with profit, carry out air-dry after fermentation again, dry, training is fried, final powder is broken into powder, the anti-caking agent for fertilizer that the present invention utilizes changing food waste to make, be added in chemical fertilizer, not only can effectively absorb water, prevent fertilizer caking, fertilizer efficiency can be improved, life-time service does not pollute the environment yet, environmental protection, production technique is simple, cost is low.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
Utilize changing food waste to make a method for degradable anti-caking agent for fertilizer, it is characterized in that concrete preparation process
For:
(1) reclaim leftovers, leftovers in 8 ~ 10kg kitchen, first filter, profit is separated with filter residue,
Profit is collected for subsequent use, remaining filter residue is put into the plastic tank of 15L, then add 2 ~ 2.5kg flyash in bucket, and mixing and stirring;
(2) the fresh ramie of 3 ~ 4kg is chosen, to join in said bucket after its chopped slagging, the limpid tap water of 1 ~ 2L and 20 ~ 30g enzymatic microorganism, 10 ~ 15g cellulase is added in bucket, a small amount of lime is sprinkled on surface after artificial mixing and stirring, pour in stack up yard, at 50 ~ 60 DEG C, carry out compost fermentation 10 ~ 15 days, after compost fermentation completes, first make wherein moisture be down to 15 ~ 20% its natural air drying, repave under being placed on the sun and be exposed to the sun 4 ~ 5 days, collect afterwards;
(3) get above-mentioned 3 ~ 4kg to dry rear solid and put into pot carry out training stir-fry 30 ~ 40min at 100 ~ 120 DEG C, training is cooled to room temperature after frying, afterwards solid is put into food steamer, water boil is added in the below of food steamer, make the water vapor of generation pass into food steamer and carry out steaming 1 ~ 2h, make it naturally cool to room temperature after having steamed, and object is taken out from cage;
(4) by profit that step (1) is collected, adjustment pH to 7.0 ~ 7.4 are carried out with massfraction 10 ~ 15% ammoniacal liquor, after adjustment, liquid is poured in fermentor tank, again object complete for above-mentioned steaming is put into fermentor tank, 10 ~ 15g bacillus aceticus is added in tank, at 30 ~ 35 DEG C, carry out anaerobically fermenting 30 ~ 40 days after being uniformly mixed, after fermentation, stirred into pureed;
(5) object of above-mentioned pureed is removed, first natural air drying 3 ~ 4 days, moisture is wherein made to be reduced to 20 ~ 30%, repave under being placed on the sun and be exposed to the sun, make it dry completely solid is put into pot first at 60 ~ 70 DEG C, to train stir-fry 20 ~ 30min afterwards, be warmed up to 120 ~ 140 DEG C afterwards and train stir-fry 40 ~ 50min again, after roasting, make it naturally cool to room temperature;
(6) material after above-mentioned training being fried takes out, and puts into pulverizer and pulverizes, sieve, filters out 70 ~ 80 object powder, collects, packs, obtain a kind of changing food waste that utilizes and make degradable anti-caking agent for fertilizer.
Application method of the present invention: the anti-caking agent for fertilizer that the present invention is obtained, be 5 ~ 7 ‰ to add with the fertile addition of ton, and mix by mechanical stirring, afterwards by chemical fertilizer bagging, place after 4 ~ 5 months, open sack inspection, find in chemical fertilizer without caking phenomenon, sowed by the chemical fertilizer adding anti-caking agent for fertilizer of the present invention, contrast with without the chemical fertilizer adding anti-caking agent for fertilizer of the present invention, crop yield is high by 2 ~ 3%.
The invention has the beneficial effects as follows:
(1) the present invention's anti-caking agent for fertilizer of utilizing changing food waste to make, is added in chemical fertilizer, not only can has water absorbing properties, can improve fertilizer efficiency;
(2) the anti-caking agent for fertilizer life-time service that the present invention utilizes changing food waste to make does not pollute the environment yet, environmental protection, and production technique is simple, and cost is low.
