Description

A kind of pig manure material focuses on and utilization of resources method

Technical field

The present invention relates to pig manure Treatment Technology field, pig farm, particularly a kind of pig manure material focuses on and utilization of resources method.

Background technology

At present general large-scale pig farm all can produce the pig manure about 10 tons every day; Adopt the nature pattern of banking up on the most pig farm of China; Muck directly mixed with dry-matteies such as stalk, sawdusts carry out long-time compost after stirring, the composting time is needs 6 months often, or could accomplish for more time.In the prior art, put down in writing for the following document of mainly containing of pig manure:

1, be that document " with the method for preparing highly efficient organic fertilizer from dungs and droppings " (notification number is CN1962559A) is applied for a patent in the China invention of ZL200610070510.1 like the patent No.; May further comprise the steps: mix and stir: feces of livestock and poultry, stopping composition and microbial starter culture thorough mixing are stirred; Pack, sign indicating number heap, fermentation dried: regular stacking earlier, pile through a sign indicating number heap-turning-sign indicating number then, get work in-process; Granulation; Pack, sign indicating number heap, fermentation dried; Pack; Wherein feces of livestock and poultry is pig manure, cow dung, chicken manure, duck excrement, and stopping composition is offal and rice bran, and microbial starter culture is the EM biological bacteria preparation.The method that the document provided; Just carried out simple processing to feces of livestock and poultry, though shortened the Production Time of fertilizer in time, lower to the comprehensive utilization ratio of feces of livestock and poultry; Used electric weight etc. all need the outside to provide, and the overall energy consumption that produces is higher.

2, be that document " processing of pig manure and utilize method " (notification number is CN101429057A) is applied for a patent in the China invention of ZL200810045547.8 like the patent No.; Comprise: 1. regulate moisture: fresh pig dung stirs, mixes with dried pig manure process, and water ratio drops to 55~60%.2. breeding earthworm: pig manure is deposited on the earthworm bed, drops into earthworm kind breeding earthworm.3. feed: the oven dry earthworm joins in the feed base-material and fits in high protein feed.4. fermentation: in the fermentation booth, pig manure carries out continuous aerobic fermentation to be handled, 5~7 days cycles, turned over throwing once in per 2 hours, and inject fresh air simultaneously, water ratio drops to 40~45%.5. dry: pig manure carries out drying treatment in pneumatic drier, water ratio drops to below 14%.6. deodorizing is handled: tail gas carries out deodorizing through wet dust collector to be handled.7. edible mushrooms base-material: pig manure is added in the fillers such as straw joint, wheat straw joint, process the base-material of culturing edible fungus.This method has been introduced the way of breeding earthworm, but whole making place is bigger, and human cost increases; And need be by a large amount of external electric energy in drying process, whole work efficiency is lower.

3, be that document " a kind of pig manure is produced the method for biological organic fertilizer " (notification number is CN101565331A) is applied for a patent in the China invention of ZL200810149876.7 like the patent No.; Moisture about 65% fresh pig dung and suitable proportion saw is unmixed; Make its carbon: nitrogen is than between 16-25; Stir with geotrichum sp or bacstearothermophilus fermenting agent then and carry out compost fermentation, turning is regularly treated that temperature of charge is reduced to dry after the envrionment temperature or air-dry; Pulverize, be the refined biometric fertilizer.Its nutrient content reaches 7%, and organic content reaches more than 50%.This method has adopted produces fertilizer with pig manure and the low dry-matter method of mixing of water ratio, and fails a large amount of nitrogen, the phosphoric that contain in the pig manure are extracted recovery; And the composting process cycle is long, and whole efficient is lower.

4, be that document " a kind of treatment process of zero pollution of waste of pig farm " (notification number is CN101531441A) is applied for a patent in the China invention of ZL200910043126.6 like the patent No.; Processing such as stable, pulverizing by fermentation,, screening; The refined organic fertilizer of the market competitiveness is conveniently used, had to output; It comprises with domestic animal pig urine collecting import methane-generating pit, anaerobically fermenting, inflow fermentation vat, with straw powder with its absorption, the pig manure that changes acidulated pool acidifying and pig manure collecting tank over to stir, nurse one's health, adjustment, one time fermentation, Secondary Fermentation, stable, pulverize, sieve, fines is processed into refined organic fertilizer; Coarse fodder returns to fermentation vat and mixes with natural pond liquid absorption reprocessing fines, output refined organic fertilizer with straw powder; Sow cub's in the field placenta, dead without reason domestic animal pig corpse were put into the burning of biogas incinerator the same day, and flue gas gets into the ventilation storehouse, bottom of stablizing the storehouse, after fertilizer filters, discharges, and residue is sent in the fermentation tower, becomes refined organic fertilizer through processing output.Adopted the dry-matter method of mixing that water ratio such as pig manure and stalk is low to produce fertilizer; And fail a large amount of nitrogen, the phosphoric that contain in the pig manure are extracted recovery; And the composting process steps is loaded down with trivial details, and the production cycle is long, and is lower to the comprehensive utilization ratio of swine excrement.

Summary of the invention
