Abstract
The invention discloses a method for producing a biogas co-production organic fertilizer through a peat gasket material. Livestock urine is added into the peat gasket material to regulate a carbon nitrogen ratio to be (25-30):1; the pH value is regulated to be 6.5-7.5, anaerobic activated sludge which accounts for 30-60 percent of the total mass of the material is added, a solid-to-liquid ratio is regulated to be 1:(1-20) g/ml, and the biogas is prepared through anaerobic fermentation within 7-40 days at the temperature of 28-50 DEG C. The production method comprises the following steps: performing anaerobic fermentation on residues through the peat gasket material, adding auxiliary materials to regulate the moisture content to be 50-70 percent, performing compost fermentation at the temperature of 50-60 DEG C for 10-40 days, granulating and drying to obtain the organic fertilizer. The problems that the peat only serves as a gasket material and is single in utilization mode, the peat gasket material is used for directly composting, pathogenic bacteria cannot be effectively killed, and the product is single and low in economic value are solved, the purposes of the peat are finally enlarged, the additional value of the peat is increased, and the economic benefits of peat mining and utilization are improved.
Description
Technical field
The present invention relates to a kind of peat gasket materials and produce the method for biogas coproduction fertilizer, belong to coal resources Application Areas.
Background technology
Coal is that China's distribution is the widest, and the Energy resources that reserves are more account for main status in the energy consumption structure of China.Coal, according to the difference of degree of coalification, can be divided into peat, brown coal, bituminous coal and hard coal.Peat (Peat) claim again the peat composed of rotten mosses or mud coal, it is the coal that degree of coalification is minimum, by the residual body of marsh plant, under the lower condition of excess moisture, poor aeration, temperature, failed fully to decompose, a kind of difficult decomposition forming through long-term accumulation is, the organism of the tiering of stable in properties.
Packing ring is showed dry ground, broken grass, peat etc. on the circle place mat of livestock.Peat has better water holding and absorption property, and therefore, available peat is done various gasket materials.Utilize peat to do the gasket materials of the domestic animals such as various horses, ox, sheep, pig, there is multiple benefit:
The first, anticorrosion, germ resistance is strong.It can suppress the corruption of ight soil and decompose, and effectively suppresses existence and the breeding of the multiple pathogenic bacteria of domestic animal.
The second, improve animal house miniclimate, for good sanitary condition is created in livestock life.Because peat water absorbability and adsorbed gas ability are strong, use peat packing ring, the gas (as ammonia, hydrogen sulfide, carbonic acid gas) that can absorb animal residue and decomposition generation thereof makes animal house keep clean, and corral inner drying is comfortable.
The 3rd, obtain high-quality barnyard manure.Utilize peat packing ring can more reasonably utilize barnyard manure.Stalk barnyard manure is in corral, and through diel nitrogen loss 10%, peat barnyard manure only loses 0. 7%.With 1t peat packing ring, can produce 4 ~ 5t high-quality organic fertilizer.
The 4th, utilize the alternative a large amount of stalks of peat packing ring, can be processed into feed or fodder additives, increase the feed resource of livestock industry.
The 5th, improve the throughput of domestic animal.Under same raising condition, livestock is raised on peat bedding and padding, and with comparing of raising on stalk or sawdust, milk amount improves 7% ~ 15%, and livestock increases weight 10% ~ 18% childhood, and birds, beasts and eggs output improves 5% ~ 12%.The 6th, peat can be made animal feed, fodder additives, fodder yeast, vitamin(e)-producing yeast etc., edible for livestock, poultry and fish.With peat forage feed domestic animal, poultry, not only expanded the source of feed, and because of the raising of nutritive value, also can promote it to grow.
Peat is applied to livestock industry as gasket materials, only utilized its good water holding and absorption property, ignore peat and be rich in organic and soil ulmin and multiple nutrients material, that causes peat utilizes mode single, the economic worth of peat resource does not fully demonstrate, and has limited comprehensive utilization and the higher value application of peat.
Summary of the invention
The technical issues that need to address of the present invention are just to overcome the defect of prior art, provide a kind of peat gasket materials to produce the method for biogas coproduction fertilizer, it utilizes peat gasket materials to mix the material feature of peat and livestock and poultry fecaluria, producing methane through anaerobic fermentation, natural pond slag is prepared fertilizer, solve peat and only done gasket materials and utilize problem and the direct compost of peat gasket materials that mode is single, can not effectively kill pathogenic bacteria, product one-sided economy is worth not high problem.The final purposes that expands peat, the added value of increase peat, improves the economic benefit of peat harvest and utilization.
For addressing the above problem, the present invention adopts following technical scheme:
The invention provides a kind of peat gasket materials and produce the method for biogas coproduction fertilizer, described method comprises the following steps:
(1) peat gasket materials interpolation livestock urine adjusting carbon-nitrogen ratio is (25-30): 1, regulating pH value is 6.5-7.5, add the anaerobic activated sludge that accounts for material total mass 30%-60%, adjusting solid-to-liquid ratio is 1:(1-20) g/ml, at 28-50 ℃, anaerobically fermenting 7-40 days prepares biogas;
(2) peat gasket materials anaerobically fermenting resistates, adding auxiliary material adjusting water content is 50%-70%, the 50-60 ℃ of rotten fermentation of heap 10-40 days, granulation post-drying obtains organic fertilizer.
Auxiliary material in step of the present invention (2) is the excrement of animals that is equivalent to residue total mass mark 30-80%, water content 50-75%.
Livestock described in the present invention is horse, ox, sheep or pig.
The present invention utilizes peat gasket materials to mix the material feature of peat and livestock and poultry fecaluria, producing methane through anaerobic fermentation, natural pond slag is prepared fertilizer, solve peat and only done gasket materials and utilize problem and the direct compost of peat gasket materials that mode is single, can not effectively kill pathogenic bacteria, product one-sided economy is worth not high problem.The final purposes that expands peat, the added value of increase peat, improves the economic benefit of peat harvest and utilization.
Thereby beneficial effect of the present invention is:
(1) the present invention fully utilizes peat gasket materials, peat and livestock fecaluria are by means of anaerobically fermenting, realize the coproduction of biogas and fertilizer, by low-carbon (LC) biomass energies such as the organic matter transformation in peat livestock fecaluria are biogas, both improved environment, realize the unification of environment benefits and economic gains, meet again national industry policy and Energy policy.
(2) the present invention fully utilizes peat gasket materials, peat gasket materials anaerobically fermenting coproduction biogas and fertilizer, the utilization of peat physical adsorption performance and chemical composition is excavated to greatest extent, by means of anaerobically fermenting, kill the pathogenic bacterium in livestock fecaluria, be conducive to improve the quality of follow-up fertilizer.
