Description
Technical field
The present invention relates to a kind of biological organic fertilizer and preparation method thereof, specifically, relate to that a kind of to take protein waste residue, the waste active carbon the like waste that the mud that produces in mycelium CSTR anaerobically fermenting, organic acid wastewater EGSB anaerobically fermenting-Aerobic and the microorganism fermentation of organic acid factory produce be 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 to take the organic waste that feces of livestock and poultry, domestic waste, agricultural crop straw, agricultural byproducts and food-processing produce be raw material, be equipped with Multifunctional fermentation inoculum agent, make it fast deodorization, become thoroughly decomposed, dewater, add again functional microbial microbial inoculum, the organic fertilizer that contains a certain amount of functional microbial processing.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 ", improves environment and guarantees 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 meanwhile, 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 declines, contaminate environment and soil, affect the Sustainable Production of agricultural, add sharp rising of the prices of the means of agricultural production such as chemical fertilizer in recent years, make agriculture production cost increase, peasant is badly in need of finding the part or all of replacing fertilizer of a kind of energy, improvement soil, the fertilizer that high-quality and efficient, price is economical, and just to efficient biologic-organic fertilizer, production provides the huge market space and commercial opportunity 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 easily to rot.Since the UNFCCC (United Nations Framework Convention on Climate Change) Kyoto Protocol in 1997 is signed, the greenhouse gas emission that carbonic acid gas and methane is representative of take becomes the important evidence that various countries carry out industry technology innovation, in the greenhouse gas emission inventory that China submits to United Nations every year, the carbon emission amount of the municipal solid wastes disposal systems such as mud is also an important content.China still has the mud of 70% left and right 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 1 ton of water ratio of every landfill is at the wet mud of 80% left and right, 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, on the basis of preserving the ecological environment, accomplish energy-saving and emission-reduction, become the problem that whole world field of environment protection is extremely paid close attention to.
In the protein waste residue that the microorganism fermentation of organic acid factory produces, contain rich in protein, if directly abandoned, cause the waste of the energy.
Summary of the invention
For addressing the above problem, the object of this invention is to provide that a kind of to take protein waste residue, the waste active carbon the like waste that the mud that produces in mycelium CSTR anaerobically fermenting, organic acid wastewater EGSB anaerobically fermenting-Aerobic and the microorganism fermentation of organic acid factory produce be 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 producing in mycelium CSTR anaerobically fermenting, methylene-succinic acid waste water EGSB anaerobically fermenting-Aerobic;
Described protein waste residue is the protein waste residue producing in methylene-succinic acid or Sunmorl N 60S production process;
Described gac is the waste active carbon producing in methylene-succinic acid or 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, 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 a kind of preparation method of biological organic fertilizer, comprises the steps:
(1) functional bacterial classification preparation
Choose functional bacterial classification, be placed in liquid culture in fermentor tank, make thalline in fermented liquid reach 10
8-10
10cfu/mL;
(2) fermenting raw materials
Dewatered sludge is mixed with protein waste residue, regulate pH value between 6.5-7.5, with urea or gac, regulate mixture C/N than between 35:1-25:1, the functional bacterial classification of access step (1) gained, carries out aerobic fermentation;
(3) aftertreatment
Step (2) gained tunning is dried, makes the mass percentage content of its moisture be reduced to 15%-20%, then pulverize, screening, granulation, get product.
Preferably, temperature≤60 ℃ of the described aerobic fermentation of above-mentioned steps (2).
Preferably, the fermentation time of the described aerobic fermentation of above-mentioned steps (2) is 10-15 days.
The invention has the beneficial effects as follows:
(1) biological organic fertilizer of the present invention is that to adopt the mud that produces in mycelium CSTR anaerobically fermenting, organic acid wastewater EGSB anaerobically fermenting Aerobic and protein waste residue, the waste active carbon the like waste of organic acid factory microorganism fermentation generation be raw material, add functional bacterial classification, the biological organic fertilizer of producing through aerobic fermentation, wherein contain nutritive element and other trace elements such as abundant nitrogen, phosphorus, potassium, meet the growth needs of crop completely;
