Abstract
The present invention is suitable for dung recovery process field, a kind of processing of livestock and poultry dung recovery is provided and utilizes method, including separating dry space from moist space, solid fermentation after separation produces organic fertilizer, liquid after separation carries out Anaerobic Treatment in black film biogas, then ceramic membrane nano-filtration membrane filter is used to carry out multistage concentration, dope is finally made organic water-soluble fertilizer after concentration, clear liquid can be used for culture zone and backwash or returning to the field, it is simple for process, low energy consumption for processing, adequately and reasonably utilize the resource in feces of livestock and poultry, realize the pursuit turned waste into wealth, solids manufacture is organic fertilizer, concentrate is produced as organic water-soluble fertilizer, clear liquid can be used for culture zone and backwash or returning to the field, both the large amount of organic and sample contained in feces of livestock and poultry was taken full advantage of, for agricultural planting, solves feces of livestock and poultry emission pollution problem again, economic benefit and environmental benefit are taken into account.
Description
Technical field
The invention belongs to dung recovery process field more particularly to a kind of resource utilization methods of feces of livestock and poultry.
Background technology
Feces of livestock and poultry excretion at present is mainly reflected in foul gas pollution to the pollution of environment, in micro- life during excrement stacking
Under the action of object, organic substance therein is decomposed and generates some foul gas, these pernicious gas contents reach certain dense
When spending can to humans and animals generate adverse effect, it is considered that ammonia, methane and hydrogen sulfide be cause farm's air pollution and
The predominant gas of smell.Even if China's large-scale pig farm using job facilities handle waste pig farm in, technological process with
Foreign technology is roughly the same, that is, one Aerobic Process for Treatment of anaerobic digestion, one Aquatic-plant Pond is separated by solid-liquid separation, due to before separation of solid and liquid, not having
PH value is effectively reduced, causes ammonia fertilizer in excrement to flow into air in the form of ammonia, also significantly to the pollution of environment.Do not have simultaneously yet
Also reduction nitrogen phosphorus and heavy metal is effectively reduced to pollute in solid and liquid manure.
Invention content
In view of the above problems, the purpose of the present invention is to provide a kind of resource utilization methods of feces of livestock and poultry, it is intended to solve
The resource utilization process of certainly existing feces of livestock and poultry is complicated, is recycled halfway technical problem.
A kind of resource utilization method of feces of livestock and poultry, the method includes following step：
S1, get out pending feces of livestock and poultry, then using separating dry space from moist space machine by feces of livestock and poultry be separated into solid excrement and
Liquid manure body；
S2, organic fertilizer is obtained after the solid excrement that step S1 is obtained is carried out fermentation process；
S3, it the liquid manure body that step S1 is obtained is discharged into black film methane-generating pit carries out anaerobic bio-treated, obtain organic sewage；
S4, the organic sewage for obtaining step S3 carry out multistage concentration using ceramic membrane nano-filtration membrane filter, obtain dope
And clear liquid；
S5, the obtained dopes of step S4 are packed, obtains organic water-soluble fertilizer, dope returns after collecting for culture zone
Rush or be discharged into farmland.
Specifically, the fermentation treatments of step S2 include by cow dung, rice husk, ammonium sulfate, fermenting agent according to following heavy
Amount ratio is sufficiently mixed to obtain initial feed：Cow dung 80~90：Rice husk 20~10：Ammonium sulfate 2~4：Fermenting agent 0.05~0.1,
Then a certain amount of nitrogenous inorganic raw material is added to the initial feed, the carbon nitrogen ratio for adjusting material is 25：1~30：
1, it obtains waiting for fermenting mixture, will wait for that fermenting mixture is placed in fermentation tank, trench bottom ventilation oxygen supply, top covers compost molecule
Film uses forced ventilation mode to be supplied oxygen for material, and oxygen concentration is kept to be more than >=15%, and temperature≤65 DEG C are fermented 24~30 days,
Obtain organic fertilizer.
Livestock and poultry dung recovery processing provided by the invention utilizes the solid fermentation life that method includes after separating dry space from moist space, separation
Liquid after production organic fertilizer, separation carries out Anaerobic Treatment in black film biogas, then ceramic membrane nano-filtration membrane filter is used to carry out
Multistage concentration, dope is finally made organic water-soluble fertilizer after concentration, and clear liquid can be used for culture zone and backwash or returning to the field, simple for process, place
Low energy consumption for reason, adequately and reasonably utilizes the resource in feces of livestock and poultry, realizes that the pursuit turned waste into wealth, solids manufacture are organic fertilizer
Material, concentrate are produced as organic water-soluble fertilizer, and clear liquid can be used for culture zone and backwash or returning to the field, had both taken full advantage of in feces of livestock and poultry and has contained
Some large amount of organic and sample are used for agricultural planting, and solve feces of livestock and poultry emission pollution problem, have taken into account economic benefit
And environmental benefit.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
A kind of resource utilization method of feces of livestock and poultry, includes the following steps：
S1, get out pending feces of livestock and poultry, then using separating dry space from moist space machine by feces of livestock and poultry be separated into solid excrement and
Liquid manure body；
S2, organic fertilizer is obtained after the solid excrement that step S1 is obtained is carried out fermentation process；
S3, it the liquid manure body that step S1 is obtained is discharged into black film methane-generating pit carries out anaerobic bio-treated, obtain organic sewage；
S4, the organic sewage for obtaining step S3 carry out multistage concentration using ceramic membrane nano-filtration membrane filter, obtain dope
And clear liquid；
S5, the obtained dopes of step S4 are packed, obtains organic water-soluble fertilizer, dope returns after collecting for culture zone
Rush or be discharged into farmland.
After a kind of livestock and poultry dung recovery processing provided by the invention handles a certain amount of feces of livestock and poultry using method, calculate
The comprehensive utilization ratio of feces of livestock and poultry has reached 82%, COD removal rates and has reached 96%.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
