Description
Technical field
The invention belongs to a kind of resource reutilization works of pig manure in pig-breeding technical field more particularly to breeding process
Skill.
Background technique
Pig is the maximum breed variety of animal husbandry, and the specific gravity that the live pig amount of delivering for sale accounts for the national always amount of delivering for sale reaches 92.06%.With
The increase of animal husbandry environmental protection pressure, many livestock and poultry farms increasingly wish that fecaluria can be in livestock and poultry farm with regard to being disappeared completely
It receives decomposition, avoids waste outlet and leak to cause damages to environment.
Large-scale pig farm excrement, sewage quantity are big and concentrate, and ten thousand pig farms generate more than 10 tons of pig manure daily, and fecaluria is dirty
More than 100 tons of water.The needs and mismatch of pig manure yield and intensive agricultural fertilizer of ploughing, in order to reduce the waste of pig manure, we once tasted
Examination prepares active carbon by raw material of pig manure, and continues on for the processing of the pig farm three wastes, but this treating capacity is relatively limited.
It is influenced by large-scale cultivation, heavy metal is usually contained in pig manure, the carbon material of heavy metal doping in recent years is continuous
It is prepared out, but there has been no the precedents prepared using pig manure as raw material.Chicken manure, pig manure slag and cow dung are heavy metal in raw material
Changing features, with the raising of pyrolysis temperature, feces of livestock and poultry charcoal yield is gradually reduced, and (Cd is removed each contents of heavy metal elements
It gradually increasing outside), most heavy metal accumulation coefficients are in reduced trend, though generally high temperature pyrolysis increases feces of livestock and poultry biology
The content of beary metal of charcoal, but also it is conducive to the volatilization migration of heavy metal in carbonization process.Content of beary metal in feces of livestock and poultry charcoal
Closely related with pyrolysis temperature, raw material sources, the heavy metal accumulation ability of each charcoal shows as chicken manure>Pig manure slag>Cow dung.
Summary of the invention
In order to solve the above technical problems, the present invention provides the methods that a boar factory discards excrement green circulatory.
The present invention is achieved by the following technical programs.
The present invention provides the method that a boar factory discards excrement green circulatory, step includes：
(1) swine excrement collected, natural air drying；
(2) swine excrement after air-drying is put into Muffle furnace, calcination 4-10h, is ground into after cooling at 100-350 DEG C
Powder；
It (3) is 1 according to mass ratio in the powder that step (2) obtains:Secondary distilled water is added in 20-50mL, in ultrasonic wave
It is ultrasonic in washer, it is separated by filtration liquid, liquid is dialysed 1-3 days, yellow solution i.e. carbon dots solution is obtained.
The dialysis is put into dialysis in secondary distilled water with the bag filter pack of MWCO=2000-3500 and obtains.
The yellow solution obtains brown carbon dots powder after rotary evaporation, drying and uses.The purpose of the calcination
It is that raw material is carbonized, swine excrement is changed into tiny carbon particle by carbonization, while realizing the enrichment of heavy metal, enrichment effect
Obtained material can be applied to detection such as needed and led by the corresponding doping that heavy metal ion is realized in carbon particle
Domain.
The present invention, which is carbonized and is dialysed by calcination, is prepared into adaptable carbon nano-particle for discarded pig manure, the present invention
The discharge for reducing pollutant improves the resource utilization during pig-breeding.Present invention provides a kind of greens
The preparation method of carbon nanomaterial, preparation method are simple.Low raw-material cost, the pig manure raw material with heavy metal accumulation is also system
Standby carbon nano-particle provides new approach.
