A kind of livestock and poultry feces efficient anaerobic fermentation device
Technical field
The utility model relates to fields, are specifically related to a kind of livestock and poultry feces efficient anaerobic fermentation device.
Background technique
With the fast development of aquaculture, some heavy metal elements are made an addition in animal and fowl fodder extensively, these heavy metals
Element is largely discharged with livestock and poultry feces, is recycled livestock and poultry feces fermentation to be applied to farmland at this time, be will cause a huge sum of money for soil
Belong to pollution.
The removal purification of heavy metal element generally uses biological treatment, i.e. livestock and poultry feces fermentation technique.Livestock and poultry feces hair
Ferment technology is the activity using microorganism, carries out biological decomposition, decomposed to the organic matter in livestock and poultry feces, turns organic waste
It is melted into organic fertilizer raw material.Organic fertilizer can be used for soil improvement, organic vegetable plantation, afforestation etc., finally realize organic waste
The innoxious use of object, and protect environment.When the conditions such as temperature, moisture, oxygen content in fermentor reach certain index, this
Slightly biological mass propagation simultaneously decomposes the organic matter contained in livestock and poultry feces.
For the customer, the anaerobic fermentation of livestock and poultry feces avoids polluting not merely for handling excrement;It is more important
Be standard of producing organic fertilizer, generate profit.To produce the organic fertilizer of standard first it is necessary to guarantee having after fermentation
Content of microorganisms, the content of organic matter, N-P-K content in machine fertilizer reach national organic fertilizer standard.By taking chicken manure as an example, chicken manure
Fermentation moisture is preferably controlled in 55% or so, however the moisture of freshly-slaughtered poultry excrement will be more than 70% or more mostly, at this moment just need to use
Auxiliary material is adjusted, moisture requirement that the moisture regulation of chicken manure is reached fermentation to 55% or so.According to national organic fertilizer standard,
The total content of NPK (NPK refers to nitrogen, phosphorus, potassium element) has to be larger than or is equal to 5%, but original N-P-K content in chicken manure
This index is not achieved, at this moment just needs to supplement by addition auxiliary material, the content of organic matter is made to meet state specified standards.Cause
This, to produce the organic fertilizer of standard, it is necessary to moisture is adjusted by addition auxiliary material, adjusts the carbon-nitrogen ratio in raw material,
Increase the content of organic matter, enhance the permeability of material, increases oxygen content when chicken manure fermenting.
