Description
Technical field
The invention belongs to animal husbandry technical field of waste treatment, and in particular to a kind of side of animal husbandry rubbish production organic fertilizer
Method.
Background technique
In recent years, with the raising of Living consumption, the consumption demand of livestock products is constantly risen, to push poultry
The continuous development of animal husbandry.Fast-developing animal husbandry also produces big while ensure that ever-increasing livestock products demand
The breeding waste of amount." rubbish is the resource for having misplaced place ", animal husbandry rubbish is also such.As long as rationally being utilized,
The cleanable energy such as biogas, bio-natural gas can not only be produced；Compost, the muck of liquid state fermentation, batch production can also be made
The organic commercial fertilizer etc. of production.Therefore the comprehensive utilization for accelerating propulsion animal waste all has weight in economy and environment
Want meaning.But in the prior art, the organic fertilizer prepared using animal husbandry rubbish, such as using the emission and disease of poultry generation
The organic fertilizer of dead poultry corpse preparation, it is slow that there is fertilizer efficiency, and fertilizer is easy to happen fever, agglomeration shows during storage
As seriously limiting the development of animal husbandry rubbish production organic fertilizer technique.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of methods of animal husbandry rubbish production organic fertilizer, can be effective
Promotion made from organic fertilizer fertilizer efficiency rate of release.
The present invention is achieved by the following technical solutions.
A kind of method of animal husbandry rubbish production organic fertilizer, including following operating procedure:
(1) by animal husbandry organic waste crush, water is added thereto, be adjusted to solid content be 20-30% after, Xiang Qi
Middle addition heavy metal scavenger, stirs evenly, until after the pH to 1.5-2.5 of upper liquid stop that heavy metal scavenger is added,
After the temperature of mixture is risen to 35-40 DEG C, and continue stir process 3-4 hours, filter residue is obtained by filtration, filter residue is washed to most
After the pH value of an ejected wash water is 6-7 afterwards, cleaning is completed, and wherein heavy metal scavenger is made of the component of following parts by weight: second
8-14 parts of ethylenediamine tetraacetic acid (EDTA), 25-30 parts of citric acid, 0.1-0.4 parts of two molybdic acid hydrate sodium, 4-7 parts of polyuridylic acid sylvite；Heavy metal
Scavenger can effectively dissolve the heavy metal in animal husbandry organic waste in the liquid phase, then be removed by filtration, to chromium, lead
Removal rate can achieve 100%, 85% or more can achieve to the removal rate of copper, zinc；
(2) filter residue after taking 10-15g to clean after drying and processing, is added into the sterile saline of 95-110ml, so
Mashing is handled afterwards, and the mashing liquid of 10ml is taken to be added into the enriched medium of 100ml, after 30 DEG C of constant temperature incubations, carries out 10-5Gradient
It after dilution, is coated on screening and culturing medium, after 30 DEG C of constant temperature incubations, chooses hydrolysis the first and second big bacterial strains of circle and ferment
Culture obtains seed liquor；
(3) by after cleaning filter residue and nutrient raw material according to mass ratio be 80-90: 1 ratio after mixing, then to its
Mixture is piled a height of 0.4-0.6m, width is 1m's after mixing by the middle seed liquor that nutrient raw material quality 2-5% is added
Rectangle material heap, and punch and ventilate every 40-50cm in the length direction of material heap, after material heap is covered with ventilative non-woven fabrics,
After compost treatment 15-20 days, organic fertilizer is obtained, wherein nutrient raw material is made of the component of following parts by weight: corn flour 33-40
Part, 10-15 parts of soybean-cake flour, 1-3 parts of bur, 2-4 parts of mulberry leaf, 1-2 parts of turnip seed powder.
Specifically, in above-mentioned steps (2), the temperature of drying and processing is 80 DEG C, and the time of drying and processing is 30min.
Specifically, in above-mentioned steps (2), enriched medium is made of the component of following parts by weight: 2 parts of potassium dihydrogen phosphate,
1 part of ammonium sulfate, 0.5 part of magnesium sulfate, 0.1 part of calcium chloride, 0.05 part of ferric sulfate, 0.01 part of zinc sulfate, sodium carboxymethylcellulose 20
