Pig manure can be resolved into a small amount of oil and charcoal, a large amount of gas by microwave high-temperature pyrolysis, and oil is gentle to be used as fuel, effectively
The charcoal for securing heavy metal may be used as adsorbent, while make pathogenic microorganism, parasitic ovum, virus in pig manure etc. in high temperature
Under the conditions of thoroughly killed, be for swine manure treatment one with broad based growth foreground and be worth explore new way.
In pyrolytic process, the micromolecular compound that nitrogen substance decomposes in pig manure can be discharged with pyrogenic steam, be formed
Gas seriously pollute air.Although being pyrolyzed the vitrifying for heavy metal in pig manure has remarkable result, silicon etc. in pig manure
Vitrifying raw material is limited to be not up to the degree being fully cured down to heavy metal.
Invention content
It is big and seriously pollute environment purpose of the present invention is to be directed to feces of livestock and poultry amount, a kind of feces of livestock and poultry minimizing, money are provided
Source, harmless treatment method, microwave high-temperature catalysis pyrolysis feces of livestock and poultry improve ammonia formation and recycling, while strengthen weight
Glassy metal.
The present invention is achieved by the following technical solutions.
Mineral catalysis agent and feces of livestock and poultry are first sufficiently mixed uniformly by the present invention, are added to and are warming up to pyrolysis temperature in advance
Microwave absorption bed, feces of livestock and poultry are decomposed reaction under the action of high temperature and mineral catalysis agent, generate pyrogenic steam, can
The condensed device of condensation portion is collected, can not condensation portion be passed through phosphoric acid solution and absorb ammonia, acquired solution further with magnesium salts
Reaction prepares guanite, and remaining solid produces the effect that heavy metal contained by slag provides carbon, silicon source in mineral catalysis agent in reactor
Lower vitrifying, environmental sound.
Specifically, a kind of method of poultry excrement and urine disposal of the present invention, includes the following steps.

Hopper is added in agent and excrement mixture, enters pyrolysis oven by feeding screw.
（3）The steam that high temperature pyrolysis generates by condensing unit condensing recovery, can not condensation portion be passed through phosphoric acid solution and fill
Divide and absorb, be further processed into guanite, to achieve the purpose that recycle nitrogen.
（4）Obtained solid product enters slag ladle, and wherein heavy metal substantially being capable of glass in the case of mineral sources abundance
Change, so that environmental sound.
Step（1）The mineral catalysis agent includes dolomite, bentonite or bentonite.Feces of livestock and poultry and mineral catalysis agent
Ratio is 1:2~4:1.
Step（2）The microwave absorption is SiC.
The present invention has the following advantages.
