Abstract
The invention discloses a method for performing pig manure resource treatment by utilizing hermetia illucens, belonging to the field of solid waste treatment. The method comprises the following technological steps: (1) mixing pig manure with oilseed meals so as to adjust the water content of pig manure; (2) performing primary fermentation to the mixture by adopting bacillus subtilis, and further fermenting with brewer yeast; (3) feeding black soldier fly Hermetia illucens for raising according to a certain proportion; and (4) after the raising period is finished, collecting the black soldier fly Hermetia illucens and ooze. The method is simple to operate, and fast for pig manure resource treatment process. After conducting the above technological treatment, pig manure and oil seed meals are converted into black soldier fly Hermetia illucens and excreta ooze thereof, the residual tetracycline antibiotics (oxytetracycline, chlorotetracycline and tetracycline) in the pig manure cannot be detected in the black soldier fly Hermetia illucens and ooze. The method not only can solve the problems of pig manure environment pollution, the antibiotics residues, human health damage and the like, but also can provide black soldier fly Hermetia illucens and ooze with rich nutrients for feed and fertilizer industries.
Description
Technical field
The invention belongs to solid waste treatment field, more particularly to a kind of recycling processing method of pig manure.
Background technology
With Animal husbandry production to modernization, intensive and scale direction develop, veterinary drug reduce animal disease with
The aspects such as the death rate, promotion growth of animal play obvious action.It is reported that, 70% or so of global antibiotic total output is used for
The consumption of animal husbandry, especially TCs account for the half of total antibiotic dosage.Numerous studies show, Tri-Biocin
After thing is entered in animal body, about 60%～90% follower excrement discharge in the form of medicine original shape or metabolite.
It is reported that, up to 4,500,000,000 tons, these excrement are applied behind farmland the discharge capacity of national feces of livestock and poultry in 2010 as fertilizer, antibiotic
By the absorption of soil, migration, degraded and plant absorption, entered into surrounding medium with various approach, and by food chain
In accumulation migrate into human body, constitute the potential hazard to human health.
The antibiotic for how being effectively reduced or removing in pig manure, it is real to prevent or reduce antibiotic to crop vivo migration
The important leverage of existing feces of livestock and poultry safe utilization.For this purpose, Chinese scholars have been carried out greatly to the biodegrading process of antibiotic in pig manure
Quantity research.It is antibiotic in During High-Temperature Composting method degraded pig manure to study at present more, and the method process cycle is longer (at least to need one
Individual month or so), and the antibiotic in pig manure can not reach it is degradable.
Black soldier flies larva nature with changing food waste, animal wastes, animals and plants corpse etc. rot organic matter as food, and
Food is efficiently converted into the nutriment of itself.In addition, black soldier flies breeding is rapid, and high conversion rate, easily management, raises into
This is low.Therefore, black soldier flies larva is used for the recycling treatment process of pig manure, antibiotic in pig manure can be not only efficiently solved
Pollution and problem of environmental pollution, and the black soldier flies larva after pig manure and worm sand can be processed for producing the animal of high value
Feed and organic fertilizer.
The content of the invention
The purpose of the present invention is the environment for existing pig manure and residual antibiotic pollution problem, there is provided one kind operation letter
It is single, the method for recycling treatment pig manure rapidly and efficiently.
Further object is that provide a kind of pig manure is converted into high value animal feed and organic fertilizer
Method.
Purpose of the invention, the present invention provides a kind of method that utilization black soldier flies carry out pig manure recycling treatment, bag
The water content that pig manure is adjusted using oil meal is included, pig manure is mixed with oil meal using bacillus subtilis and saccharomyces cerevisiae
Compound is fermented, and realizes the steps such as the recycling treatment process of pig manure by raising black soldier flies larva, and its concrete steps is such as
Under：
A kind of method that utilization black soldier flies carry out pig manure recycling treatment, is carried out as steps described below：
(1) it is 40%～70% that pig manure mixes to water content mass percent with oil meal；
(2) mixture of pig manure and oil meal is sterilized 15 minutes in 121 DEG C, be cooled to inoculation 2% after room temperature～
Bacillus subtillis (Bacillus subtilis) nutrient solution after 10% (v/w) activation, ferments 1～3 day in 37 DEG C；Again
Saccharomyces cerevisiae (Saccharomyces cerevisiae) nutrient solution being inoculated with after sterilizing after 5%～10% (v/w) activation, in 28
DEG C fermentation 2～5 days；
(3) by the mixture after fermentation in black soldier flies larva (Hermetia illucens L.) and (2) with mass ratio 1:1
～1:5 ratio is mixed；
(4) breeding cycle of black soldier flies larva is 10 days or so, and breeding cycle collects black soldier flies larva and worm sand after terminating.
Black soldier flies larva, worm sand and the feed not taken food can be respectively used to feed and fertilizer production.
Wherein described oil meal is Cottonseed Meal, rapeseed dregs, dregs of beans, sunflower seed dregs etc..
The present invention is using fermentable and raises the recycling treatment that black soldier flies larva realizes pig manure, to taking food pig manure 10
TCs is determined in the black soldier flies larva of it or so and worm sand.As a result show, black soldier flies larva polypide and
Conventional three kind TCs (terramycin, aureomycin and tetracycline) is not detected by worm sand.
Because the mixture that present invention employs using fermentation pig manure and oil meal raises black soldier flies larva, final product
For black soldier flies larva and worm sand, the recycling treatment time of pig manure is short, and black soldier flies larva and worm sand can be respectively used to feed and
Fertilizer production, realizes the recycling treatment process of pig manure.
