Abstract
The invention discloses a kind of production technology of pig manure fermentation producing methane, comprise the steps of：1）Pretreatment：Live pig excrement is diluted with water, then mixed liquor passes through grid filtration, removes straw and suspended article in mixed liquor, then deliver to mixture pump in catch-basin；2）Acidifying：Delivered in mixed liquor after desanding in hydrolysis acidification pool, suspended material in degraded mixed liquor；3）Anaerobic fermentation：Mixed liquor after acidifying is delivered in anaerobism generator, anaerobic fermentation is carried out, fermentation temperature is set to 35 ~ 38 DEG C, biogas is produced after fermentation；4）Collect：After obtained biogas is separated through moisture trap, during biogas sends into gas storage holder at the top of separator, the biogas got product.The gas production of biogas when the present invention can improve live pig manure fermentation.
Description
Technical field
The present invention relates to a kind of production technology of pig manure fermentation producing methane, applied to pig manure recovery technology field.
Background technology
With the fast development of pig-breeding industry, the problem of bringing therewith has live pig excrement concentrations and rinse water
Substantial increase, live pig excrement concentrations cause various infectious diseases to grow, therefore processing is each cultivation in time by live pig excrement
The problem of field must primarily be solved, common processing mode is dries or fermented in the market, and organic composite is processed into drying
Biogas can be made in fertilizer, fermentation, but in fermentation, technique is immature so that live pig excrement is not fully utilized.
The content of the invention
For above-mentioned technical problem, the invention discloses a kind of production technology of pig manure fermentation producing methane, it is possible to increase raw
Swine excrement utilization rate, makes methane gas producing amount high.
The invention discloses a kind of production technology of pig manure fermentation producing methane, comprise the steps of：
1）Pretreatment：Live pig excrement is diluted with water, then mixed liquor passes through grid filtration, removes the straw in mixed liquor and hang
Float product, then deliver to mixture pump in catch-basin；
2）Acidifying：Delivered in mixed liquor after desanding in hydrolysis acidification pool, suspended material in degraded mixed liquor；
3）Anaerobic fermentation：Mixed liquor after acidifying is delivered in anaerobism generator, anaerobic fermentation is carried out, fermentation temperature is set to 35
~ 38 DEG C, biogas is produced after fermentation；
4）Collect：After obtained biogas is separated through moisture trap, biogas in feeding gas storage holder, is got product at the top of separator
Biogas.
The beneficial effects of the invention are as follows：Live pig excrement is made by fermentation can as fuel biogas, waste material utilize, energy
The hygienic conditions around plant are enough improved, bacterium infection are reduced, while using the technical program, it is possible to increase live pig excrement
Effective rate of utilization, improves the gas production of biogas.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Specific embodiment is closed, the present invention is expanded on further.
The invention discloses a kind of production technology of pig manure fermentation producing methane, comprise the steps of：
1）Pretreatment：Live pig excrement is diluted with water, then mixed liquor passes through grid filtration, removes the straw in mixed liquor and hang
Float product, then deliver to mixture pump in catch-basin；
2）Acidifying：Delivered in mixed liquor after desanding in hydrolysis acidification pool, suspended material in degraded mixed liquor；
3）Anaerobic fermentation：Mixed liquor after acidifying is delivered in anaerobism generator, anaerobic fermentation is carried out, fermentation temperature is set to 35
~ 38 DEG C, biogas is produced after fermentation；
4）Collect：After obtained biogas is separated through moisture trap, biogas in feeding gas storage holder, is got product at the top of separator
Biogas.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and that described in above-described embodiment and specification is only the present invention
Preference, be not intended to limit the present invention, without departing from the spirit and scope of the present invention, the present invention also have it is various
Changes and improvements, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by institute
Attached claims and its equivalent thereof.
