Description
Technical field
It is related to biomass power plant ash, flour mill's leftover bits and pieces and poultry the present invention relates to recycling field, especially one kind
The method that poultry manure recycling produces organic fertilizer.
Background technology
China is widelyd popularize biomass electric power plant as a kind of sustainable energy, thing followed biomass electricity
The amount of factory's ash also increases sharply, and the utilization ways of current Power Plant Ash are also extremely limited, and Power Plant Ash overstocks problem has turned into biomass
Power plant's a great problem, therefore, it is badly in need of expanding the utilization orientation of biomass power plant ash, solution biomass ash overstocks and resource increases
Value Utilizing question.
As China livestock and poultry breeding industry is fast-developing and scale constantly expands, thus the discharge capacity of feces of livestock and poultry also drastically increases
Plus, if a large amount of feces of livestock and poultry are dealt with improperly or not in time, will turn into new pollution sources, cause a series of environmental problems, with people
Environmental consciousness enhancing, the process problem to feces of livestock and poultry is also more and more urgent.
At present, the mode that livestock and poultry dung recovery is utilized is mainly using hot fermentation production organic fertilizer, but due to livestock and poultry
Dejecta moisture is high, and Penetration ration is poor, is unfavorable for fermentation, thus need to add auxiliary material reduction dejecta moisture and improve fermentation bar
Part, reaches the purpose of Rapid Fermentation.Conventional auxiliary material is just like wheat bran, dregs of beans, husk, straw end etc., although comprehensive nutrition, but in hair
The ferment middle and later periods causes carrier matrix blocking because of nutrient consumption, and permeability and mass-and heat-transfer are deteriorated, and influence fermentation biomass enters one
Step is improved；Although the inert carrier such as solid fermentation such as sepiolite, sponge, modified zeolite is preferable, without any trophic function, and
Cost is higher.
The Chinese patent literature of publication number CN102424613A is disclosed and made with biomass ash compost using fowl and animal excrement
The method of organic fertilizer, but it has the disadvantage high alkalinity not in view of biomass power plant ash, is unfavorable for that microbial fermentation is produced organic
Most elements in fertilizer, and fertilizer are (such as：P, Si, Fe, Zn, Cu, Mn, Mo etc.) it is difficult to be absorbed by crops profit in stationary state
With.The Chinese patent literature of publication number CN 102992827A discloses a kind of Active organic bacterial fertilizer and preparation method thereof, specific public
A kind of active organic bacteria prepared as raw material with plant ash, furfural dregs or other contents of organic matter agriculture and industry waste high is opened
The method of fertilizer, but furfural dregs contain too high salinity, are unfavorable for microbial fermentation, and the salt damage effect to soil may be aggravated,
And need high temperature to dry during making organic fertilizer, and organic fertilizer high cost is led into, it is unfavorable for utilization and extention.
The Chinese patent literature of Publication No. CN 103288499A discloses a kind of ecological organic pot for growing seedlings and its preparation side
Method, a kind of pure natural organic ecology is produced using bark, sawdust, plant ash, feces of livestock and poultry, bio-feritlizer leavening, Testa Tritici
The method of nutritive cube, but the method fermentation time is long, troublesome poeration, and fermentation thoroughly, does not produce peculiar smell influence surrounding environment.
The content of the invention
The technical problems to be solved by the invention are for above-mentioned deficiency, there is provided one kind utilization biomass power plant ash,
Flour mill's leftover bits and pieces is auxiliary material, and feces of livestock and poultry is raw material, is stacked using totally-enclosed outer rotary roller hot fermentation coupling nature
Fermentation, it is intended to which stench, the fermentation period for solving feces of livestock and poultry organic fertilizer preparation process are long, the problems such as cost of labor is high.
A kind of method that utilization biomass power plant ash, flour mill's leftover bits and pieces and feces of livestock and poultry produce organic fertilizer, including with
Lower step：
Step (1)：Batch mixing is obtained to biomass power plant ash, flour mill's leftover bits and pieces and fermenting agent is added in feces of livestock and poultry；Institute
The addition for stating flour mill's leftover bits and pieces be make batch mixing C/N ratios be 25~35: 1；The pH value of described biomass power plant ash is 6.0
~8.0；The addition of the fermenting agent is 3 ‰~the 4 ‰ of feces of livestock and poultry quality；By under biomass power plant ash, flour mill
The water content of heel regulation and control batch mixing is to 50~60wt%；
Step (2)：By the batch mixing of step (1) be placed in temperature in totally-enclosed outer rotary roller and at 65 DEG C~75 DEG C,
Ferment to obtain Curing material substantially under excess oxygen；
