Pig dung handles: Hoggery pig dung handles program -- pig dung processor, firedamp ferments bag, compost ferments processing
Pig dung processor does pig dung oxygen of be disgusted with of cropland, organic fat high temperature is returned to ferment the fertilizer that make, firedamp ferments directly after wet depart ferments, feed of excrement and urine is changed and compost processing.
Although processing technique of cultivate birds excrement and urine is very much, but the experience according to developed country and our country, before the masses is to use compost to handle junior travel resource to change use, dung of the research and development as science and technology, innovation, new generation corrupt processing equipment comes out -- pig dung processor, firedamp ferments bag
One, effect of processing of pollution of excrement and urine of pig of opposite of pig dung processor and value
1, the dung of excrement and urine that handles via dehydrate of pig dung processor does not have a stink approximately, agglutinant small can do base manure, top application to use, its fertilizer efficiency is long, fat sex is stable, complemented the NPK in soil and microelement, those who abounded soil is organic qualitative, overcame constant to fertilize makes edaphic salt alkaline hardened defect, had the effect of improved soil. Via carrying out a proof, below coequal unripe chief condition, relatively other fertilizer fertilizer efficiency is better.
2, the concentration of nutrient of dry excrement and urine that pig dung processor handles is high, decompose easily, absorb fast, duration is long. Belong to hot manure, stimulative crop root system develops, enhance crop photosynthesis, those who raised crop is sweet degree, beautiful degree, increase production is added close.
3, pig dung processor squeezes dry dry pig dung to do adult fish at the same time the good feed with the earthworm. Sell as organic fertilizer can obtain additional economic benefits.
2, firedamp ferments bag processing breeds pollution
1, increase high grade but second birth the sources of energy is supplied, alleviate the double pressure that industry of energy of pressure of national energy resources, our country is facing economic growth and environmental pollution, development is used but second birth new energy resources has great sense. Firedamp is all sorts of organic material in isolation air (the reproducibility conditions; , below appropriate temperature humidity condition, one kind when arise through microbial action can burn gas. As a kind of high-energy and high grade the sources of energy, firedamp more and more get the welcome of people. The bases of firedamp is methane, 60% of all sorts of gas that take a generation about? 80% . Methane is a kind of ideal gas fuel, it is colorless insipidity, after mixing with right amount air, can burn. After 1 stere firedamp burns completely, can arise be equivalent to at 0.7kg anthracitic offerred quantity of heat.
Firedamp is a kind of clean the sources of energy, can replace coal, rise to reduce the effect that discharges carbon dioxide, project of methane of combustion, country, be known as construction resource is managing model energy project of the society, construction environment is friendly model zoology project of the society, increase the rich laborer Cheng of farmer income, improve a country to produce the clean project of living conditions, do real issue to handle project of meddlesome common feelings of people for the farmer. This project builds methane project, be helpful for promoting economy of project area loop to develop, improve zoology environment, stimulative agriculture structural adjustment and farmer are added close cut down expense.
2, be helpful for realizing zoology breed aquatics, promote energy-saving decrease platoon and progress of area loop economy
As breed a quantity to increase ceaselessly, the litter such as the excrement and urine that the farm discharges everyday increasingly grow in quantity, cause serious environmental pollution not only, and cause cultivate birds easily to cause disease, affect breed aquatics epidemic prevention sanitation directly, reduce productivity level, restrict the expanded reproduction of the farm and safe production thereby.
Build methane project, firedamp was joined to use this one segment in not complete agriculture loop, become a closed complete agriculture loop with respect to what can make. Methane project is in complete agricultural loop system, can quicken agriculture the integrated development between departmental door, more sufficient favourable geographical position produces the energy of results and material with agriculture, can move energy-saving source, feed, fertilizer 3 person the relation between, purify an environment, reduce pollution, protect water natural resources, enhance edaphic fertility, reduce the use of chemical fertilizer, achieve thereby energy-saving decrease a platoon, protect agricultural ecological balance, promote farming the development of animal husbandry.
Excrement and urine of use cultivate birds produces marsh gas, provide fuel for the dweller. Current, this kind of craft is already mature, a lot of places had built firedamp pool, according to investigation, the whole nation already built large and medium-sized methane project many 460, pool cubage achieves L3 10 thousand M, year processing agriculture litter 30 million T, annual produces gas to amount to 20 million M. But the need when be being used at making marsh gas makes excrement and urine is in the environment that do not have oxygen, scale of nitrogen of organic matter carbon is 25~1 commonly, firedamp
3, processing of soak of caboodle of hoggery pig excrement and urine manufactures organic fat technology
Alleged compost ferments, the bacterium needing oxygen that uses cultivate birds excrement and urine mucky at one's convenience before fertilization namely is many when having oxygen characteristic of progenitive, barmy, resolve the harmful to crop matter in excrement and urine, the organic matter in letting cultivate birds excrement and urine namely ferments in great quantities decompose, generation quantity of heat (every kilogram dry matter produces quantity of heat for 16: 7, 20: 9MJ, promote organic matter decompose, evaporate moisture. Is the temperature when compost ferments as high as 6O? , the harmful to crop material such as seed of the bacterium of cause of disease in can exterminating material, helminth egg, fireweed, ensure pair of plants are harmless, stable, still have at the same time maintain the ability with rich soil. Compost is changed can divide had better oxygen compost and compost of oxygen of be disgusted with, good oxygen compost calls high temperature compost again, because high temperature compost is had,cost little, organic matter decomposes short, peculiar smell to wait for outstanding advantage adequately, becoming research to develop the heat that handles excrement and urine at present. Using compost method to handle the gain of cultivate birds excrement and urine is the final result that ~ handles
Current, pig dung basically has two kinds of different processing technique ~ as fertilizer
(1) compost zymotechnics. Pass the pig dung after compost ferments, it is grape, watermelon, fruiter and vegetable good fertilizer. Apply extensively at all sorts of crop, it is the high grade fertilizer that production does not have social effects of pollution, green and organic product. The choice is in ventilated the place with good, high relief, had better be far from next wind direction of living area and above of henhouse 500 M, will clear the area that give fills up mound of makings pig dunghill, close with slop outside. General summer 10 D is controlled, 2 months control winter. This method cannot complete deodorization.
(2) drying (or airing) after smashing, use at fertilizer. Dung of will little pig uses device of pig dung drying dry (because bright chicken dung has very strong toughness, need adds a large number of dispersing complementary makings) . After gallinaceous dung drying smashs, still can machine granular fertilizer.
2 as feed
Pig dung is the good feed of cattle. Nitrogen is contained in pig dung much, first pig dung drying or airing, eliminate is harmful material and off-odour, the convention that feeding a swine again joins 1O in feed, gallinaceous dung, already replaceable concentrated feed, can promote live pig to grow again. Join in the feed such as the corn of ox, sheep, rice bran 15, to 3O, gallinaceous dung, its effect
Edaphic fertility enhances in the agricultural production of Chinese number chiliad already through using excrement and urine, traditional pattern uses the method of filling, gasket or compost means to make cultivate birds excrement and urine farmhouse fertilizer. Study most still is compost law currently. Compost still is one of effective methods that handle all sorts of organic litter at present, the organic fertilizer that compost produces is applied conduce to improved soil structure at farm, raise organic qualitative content of soil, stimulative crop increase production.
The basic measure of compost sees a picture 1.
3, compost flow
Groovy compost method ferments to pile up naturally, the problem of existence is the loss that there is NH in handling a process, cannot control bad smell completely, and the space that compost needs is large, the time that handles a need is long. Because this has a lot of research to be in compost at present mix into person is efficient ferment microbial if EM(is effective microbial bacterium group) or physics, chemical conditioner is like wood chip, sawdust, rice husk to wait, adjust the carbolic nitrogen in excrement and urine is compared, control undertakes fermenting below proper moisture, temperature, oxygen, acid-base value, can reduce the volatilization with angry ammonia, shorten compost time, control effluvial generation. The final result bad smell that the profit that uses compost method to handle cultivate birds excrement and urine is handling at ~ is less, and drier, pack easily, scatter apply. Defect still is the loss that there is azotic element in handling a process, cannot control bad smell completely, the space that compost needs is large, processing time is long. Somebody puts forward to use the method that ferments the storehouse adds microbial preparation, can reduce the loss of NH and can shorten compost time. But also research shows the source outside fermenting be added in the process is microbial not big to compost process and compost quality influence, can increase compost cost E6] instead. Organic fat manufacturer is in birds of a few cultivate to ferment groovily use method increases to zymotechnics of law of zymotechnics of oxygen of be disgusted with, fast drying, microwave law, trends full oxygen waits on methodological foundation. The demand that increase of demand ceaselessly to having produce of social effects of pollution as people and can expand continuously, also expanding ceaselessly to the demand of organic fertilizer of high grade commodity, excrement and urine of the birds that use domestic animal makes organic fertilizer have very great market potential.
