Problems solved by technology

[0003] 1. Serious environmental pollution
[0004] After the initial fermentation, the feces are directly splashed on the surface of the roots of the crops, resulting in the spread of harmful bacteria; the second barge and transportation leakage of the feces in the urban septic tank during the process of transportation, transportation pollution and artificial unloading of manure have led to urban infection. At the same time, it also caused the water quality of the rivers around the city to deteriorate; the evaporation of toxic gases during the drying process of poultry manure produced air pollution
[0005] 2. Low fertilizer efficiency
[0006] After the initial fermentation, the manure is splashed on the surface of the roots of the crops, and it is naturally diluted and differentiated by the natural influence of temperature, wind and rain, and the fertilizer efficiency is low; the evaporation of a large amount of organic ammonia during the drying process of poultry and livestock manure reduces the organic fertilizer. effective element
The simple treatment of biological manure wastes extremely valuable organic fertilizer resources

Embodiment 1

[0067] Referring to Fig. 1, the production method of embodiment 1 of the present invention comprises following production steps:

[0068] 1. Sterilize, deodorize and decolorize the feces in the septic ozone tank 1 .

[0069] The septic ozone tank is mainly connected with a temperature-controlled fermentation device 11 , an ozone generator 12 , an automatic sampling analyzer 13 and a tunneling type sewage valve 14 .

[0070] Use the temperature-controlled fermentation device 11 to ferment and control the fermentation time for 10 hours, spray phage bacteria at a temperature of 25° C., and carry out targeted sterilization treatment on the feces in the septic tank for 6 hours.

[0071] Carry out sterilization, deodorization and decolouring treatment with ozone generator 12, and the reaction temperature of automatic ozone generator is 12 ℃, and PH is 7, and working time is 10 minutes. The ozone generator 12 of the present invention is a layered grid ozone generator.

Embodiment 2

[0090] Other steps of the method of the present embodiment are identical with embodiment 1, change in the following aspects:

[0091] 3. Centrifugal dehydration, freeze drying

[0092] Use centrifuge 31 to carry out dehydration, and automatic orbital type top-spin centrifuge carries out dehydration treatment, and the rotating speed is 3000r / m, after dehydration treatment, carry out freeze-drying treatment through freeze-drying chamber again, the temperature is -4 ℃, then use conveyer belt 32 to feed to Impurity separation pool 4. At the same time, the organic nitrogen, phosphorus, and potassium components in the wastewater are extracted by extraction method, and used as added nutrients during granulation.

[0093] 8. Synthetic granulation

[0094] In the synthetic granulation workshop, the ultraviolet-sterilized base fertilizer is evenly mixed with the organic nitrogen, phosphorus, and potassium additives extracted from the wastewater, and then the surface is coated with a p...

Abstract

The regularly released granular organic fertilizer has manure as basic material and added nitrogen fertilizer, phosphate fertilizer, potash fertilizer, rhizobium and plant growth promoter and is produced into 0.0001-0.15 mm size coated agent. It is produced through a computerized control process, including disinfection with bacteriophage, disinfection with ozone generator, deodorizing, decoloring, centrifugal dewatering, freeze drying, sieving to eliminate impurity, mixing, coating with one layer of degradable plant casing, etc.

Description

technical field [0001] The invention relates to a bio-strengthening fertilizer prepared by using natural organic fertilizers and a production method thereof, in particular to a regular slow-release granular organic fertilizer and a production method thereof. Background technique [0002] At present, domestic bio-fertilizer technology is still in the sub-completion stage, and there are no relevant reports and introductions on the scientific and rational concentration and deep processing of feces to make slow-release granular organic fertilizers at home and abroad. The products developed by various domestic manufacturers have a single structure, quick volatilization of spraying fertility, poor effect, and cannot meet the needs of modern ecological agriculture in terms of quality, quantity and price. Generally, bio-organic fertilizers are basically fermented using toilet manure and then sprinkled on the surface of the roots of crops. The more advanced ones are simple treatments...
