Description
Technical field
The present invention relates to agricultural fertilizers, can Specifically be delayed the present invention relates to a kind of using the production of industrial enzyme preparation filter residue
The fertilizer released.
Background technique
China is industrial enzyme preparation big producer, and there are more than 200 families of enzyme preparation producer in the whole nation, generate a large amount of enzyme preparation every year
Filter residue.The problem of how handling enzyme preparation filter residue, becoming producer's headache.International enzyme giant uses at high temperature in the company of China
After reason, freely to peasant as fertilizer returning to the field.Since this departmental cost is very high, most domestic producer is unwilling to invest, substantially
On be disorderly leave about, cause environmental problem, resident can't bear it and disturb, and environmental protection administration is also difficult to administer from source.
Industrial enzyme preparation especially amylase, carbohydrase in process of production, since fermentation liquid is sticky, in extraction process
In, the diatomite progress flocculation treatment of the bentonite of the 5-7% of fermentation liquid weight, the perlite of 1-2%, 1-2% is added, in plate
Filter residue is formed after frame filtration treatment.Perlite, the 4.6%- of bentonite, 4.6%-5% in industrial enzyme preparation filter residue containing 23-25%
The fermentation organic acids such as thallus, sulfate of 5% diatomite, 10--12%, the moisture content of 68.8%-53%.
Bentonite, bentonite have strong hygroscopicity and dilatancy, the water of adsorbable 8-15 times of own vol, volume
It expands up to several times to 30 times, has certain adsorption capacity to various gases, liquid, organic substance, maximal absorptive capacity is up to 5 times
In the weight of itself.
Diatomite is a kind of siliceous rock, is a kind of biogenic siliceous sedimentary rock, it is mainly by the something lost of ancient times diatom
The bones of the body are formed, and specific surface area 40-65m/g, pore volume 0.45-0.98m, water absorption rate is 2-4 times of own vol, in electron microscopic
It can be observed that special porous construction under mirror.
Perlite is a kind of acidic lava of volcanic eruption, through glassy rock made of quick refrigeration, because it has
Pearl fissured structure and gain the name, when perlite is heated to 850-900 DEG C, due to the nature of glass soften, wherein moisture evaporate, make
It at volume expansion, can achieve 7-16 times of original volume, be expanded perlite, it can be as the filter aid of enzyme preparation.
And handled there are three types of industrial enzyme preparation filter residues at present, first is that high-temperature calcination, fertilizer returning to the field, feature are that investment is high, at
This height.Second is that drying, but a large amount of peculiar smell can be generated in drying course, cause secondary pollution.Third is not handle, and is arbitrarily disorderly arranged
It leaves about, causes problem of environmental pollution, and the third mode that domestic manufacturer largely uses at present.
It is proposed the present invention be directed to the rear extraction filter residue of industrial enzyme preparation especially high viscosity fermentation liquid processing problem
A kind of low-cost technologies scheme, according in industrial enzyme preparation filter residue containing a large amount of bentonites with suction-operated, tripoli and
The characteristics of organic and inorganic fertilizers such as ammonium sulfate, thallus, by enzyme preparation filter residue bank up fermentation, addition inorganic nitrogen, phosphorus, potassium without
Element, then binder bentonite or the Yellow River stain soil are added, the agricultural slow-release fertilizer for being granulated, being dried and being become a kind of high value,
It can be widely applied to wheat, corn, apple fruits and vegetables, flowers fertilizer.
Summary of the invention
It using industrial enzyme preparation production leftover bits and pieces filter residue is one of raw material that the present invention, which provides a kind of, adds inorganic nitrogen, phosphorus, potassium
Element, then add binder carclazyte or the Yellow River stain soil etc., the agricultural slow-release fertilizer for being granulated, being dried and being become a kind of high value
And the preparation method of this fertiliser granulates.
Slow release fertilizer of the invention includes that following component is constituted: nitrogen source, calcium superphosphate, potassium sulfate, industrial enzyme preparation filter
Slag, binder.
Nitrogen source can be carbon ammonia, nitre ammonia, urea or the mixture of three, preferably use urea.
Binder can be the Yellow River stain soil, carclazyte, clay or three's mixture, preferably use carclazyte.
The production of 5 meters wide, 3 meters of depths, length according to annual enzyme preparation filter residue is dug in the fermentation of industrial enzyme preparation filter residue on the ground
Amount, by 10-40 meters of 4, the ponds being adjusted and carries out Anti-seeping technology, the enzyme preparation filter cake generated daily is deposited in pond
In, after being higher by 30-50 centimetres of pond, is covered tightly sealing 3-5 months after regular with plastic film and carry out fermentation curing, then sequentially followed
Ring uses.
By weight by 20% nitrogen source, 10% calcium superphosphate, 5% potassium sulfate, 40% fermentation after industrial enzyme preparation filter
Slag, 20% binder, stirs evenly in blender, and adjusts moisture content to 39-41%.
It is transported to wet granulator by prepared raw material to be granulated, dry, screening, packaging.
Fertilizer grain preparation method of the present invention is simple, effect is reliable, low in cost, and entire treatment process is pollution-free and peculiar smell produces
It is raw.The fertilizer obtained through the present invention has extraordinary slow release, solves the pollution problem of industrial enzyme preparation solid waste, has well
Market prospects.
