Description
Technical field
The present invention relates to a kind of biological organic fertilizer and preparation method thereof, specifically, relate to protein waste residue that a kind of mud that produces in mycelium CSTR anaerobically fermenting, the organic acid wastewater EGSB anaerobically fermenting-Aerobic and organic acid factory microbial fermentation produce, waste active carbon the like waste as raw material, add functional bacterial classification, biological organic fertilizer of producing through aerobic fermentation and preparation method thereof.
Background technology
Biological organic fertilizer is that the organic waste that produces take feces of livestock and poultry, domestic waste, agricultural crop straw, agricultural byproducts and food-processing is as raw material, be equipped with the Multifunctional fermentation inoculum agent, make it fast deodorization, become thoroughly decomposed, dewater, add again the functional microbial microbial inoculum, the organic fertilizer that contains a certain amount of functional microbial that processes.Biological organic fertilizer is the new-type fertilizer of the Ministry of Agriculture and State Administration for Quality Supervision and Inspection and Quarantine's keypoint recommendation.The Ministry of Agriculture of the People's Republic of China, MOA points out to advocate energetically production and the application of development biological organic fertilizer in the meeting of " ten large practical techniques are promoted in outstanding ten major tasks ", improve environment and guarantee that the safety of food has become the vital task of whole society's development.In recent years, country has strengthened investment in agriculture, and most province has been cancelled agricultural tax and strengthened the dynamics of agriculture subsidy, and simultaneously, the selling price of agricultural-food is skyrocketing, and farmers' income has increased, and enthusiasm for production is surging.But long-term application chemical fertilizer, agricultural chemicals make the hardening soil, fertility descends, contaminate environment and soil, affect the Sustainable Production of agricultural, add in recent years sharp rising of the prices of the means of agricultural production such as chemical fertilizer, agriculture production cost is risen, the peasant is badly in need of seeking the part or all of replacing fertilizer of a kind of energy, improvement soil, high-quality and efficient, fertilizer that price is economical, and just production provides the huge market space and commercial opportunity to efficient biologic-organic fertilizer for this.Biological organic fertilizer is the agriculture in the future main production means, is a huge enterprise that is worth investment, is a sunrise industry that earning rate is high.
Mud is normal companion's product of waste water and solid waste anaerobically fermenting, and water ratio is generally more than 90%, although it contains a large amount of organic matters, plant nutrient, also contains pathogenic bacteria, parasite (ovum) simultaneously, and it is smelly to rot easily.Since the UNFCCC (United Nations Framework Convention on Climate Change) Kyoto Protocol in 1997 is signed, greenhouse gas emission take carbonic acid gas and methane as representative becomes the important evidence that various countries carry out the industry technology innovation, in the greenhouse gas emission inventory that China every year submits to United Nations, the carbon emission amount of the municipal solid wastes disposal systems such as mud also is an important content.China still has the mud about 70% not obtain stabilization, harmless treatment at present, the overwhelming majority is still and is sent to municipal refuse disposal area and carries out simple landfill, and the wet mud of 1 ton of water ratio of every landfill about 80%, will produce the total release of 0.5 ton of carbonic acid gas, and to a large amount of methane of environmental emission, its Greenhouse effect are the decades of times of carbonic acid gas, and therefore, secondary pollution is serious.Therefore, how mud is processed through science, made it reach minimizing, innoxious and resource utilization, accomplish energy-saving and emission-reduction on the basis of preserving the ecological environment, become the problem that whole world field of environment protection is extremely paid close attention to.
Contain rich in protein in the protein waste residue that organic acid factory microbial fermentation produces, if directly abandon, cause the waste of the energy.
Summary of the invention
For addressing the above problem, the purpose of this invention is to provide protein waste residue that a kind of mud that produces in mycelium CSTR anaerobically fermenting, the organic acid wastewater EGSB anaerobically fermenting-Aerobic and organic acid factory microbial fermentation produce, waste active carbon the like waste as raw material, add functional bacterial classification, biological organic fertilizer of producing through aerobic fermentation and preparation method thereof.
For achieving the above object, one of technical scheme provided by the invention is a kind of biological organic fertilizer, and described fertilizer is that the raw material by following proportioning is prepared from: (1) dewatered sludge 50-80 weight part; (2) protein waste residue 10-50 weight part; (3) urea 0-10 weight part; (4) gac 0-10 weight part; (5) functional bacterial classification microbial inoculum 0.2-1 weight part;
And described dewatered sludge is the mud that produces in mycelium CSTR anaerobically fermenting, the methylene-succinic acid waste water EGSB anaerobically fermenting-Aerobic;
Described protein waste residue is the protein waste residue that produces in methylene-succinic acid or the Sunmorl N 60S production process;
Described gac is the waste active carbon that produces in methylene-succinic acid or the Sunmorl N 60S production process;
Described functional bacterial classification microbial inoculum is the composite flora of one or more compositions in bacillus azotobacter, organophosphorus bacterium, the potassium bacterium.
Preferably, by percentage to the quality, the water ratio of described dewatered sludge is 80%.
Two of technical scheme provided by the invention is preparation methods of a kind of biological organic fertilizer, comprises the steps:
(1) functional bacterial classification preparation
Choose functional bacterial classification, place liquid culture in the fermentor tank, make that thalline reaches 10 in the fermented liquid
8-10
10Cfu/mL;
(2) fermenting raw materials
Dewatered sludge and protein waste residue are mixed, regulate pH value between 6.5-7.5, regulate mixture C/N than between 35:1-25:1 with urea or gac, the functional bacterial classification of access step (1) gained carries out aerobic fermentation;
(3) aftertreatment
With step (2) gained tunning oven dry, make the mass percentage content of its moisture be reduced to 15%-20%, pulverize again, screening, granulation, get product.
Preferably, the temperature of the described aerobic fermentation of above-mentioned steps (2)≤60 ℃.
