Abstract
The present invention relates to a kind of organic fertilizer production technique, be specifically related to a kind of organic fertilizer production technique of diary farm, this technique includes following key step: 1) cow dung urinates pre-anaerobically fermenting, 2) cow dung urine separating dry space from moist space, 3) waste water sends into methane-generating pit process, 4) dry cow dung and cripple, chicken manure, microbiobacterial agent and straw powder are according to the weight ratio Homogeneous phase mixing of 6.5:1:1:0.0000105:1.5, and 5) mixture is loaded fermenter anaerobically fermenting, 6) Secondary Fermentation, 7) obtain fertilizer; Adopt the organic fertilizer production technique of technical solution of the present invention, cow dung urine can be become fertilizer, pollute to solve it, improve economic worth simultaneously.
Description
Technical field
The present invention relates to a kind of organic fertilizer production technique, be specifically related to a kind of organic fertilizer production technique of diary farm.
Background technology
Because modernization pasture cultivation scale is large, discharge cow dung urine volume every day greatly, relate to the crucial problem that the process of cow dung urine is the development of puzzlement pasture always.
Along with the fast development of economy, improving constantly of Living consumption, the dietary structure of people also in change gradually, particularly to the demand of dairy product also in continuous increase.The continuous expansion of city size and extension; livestock-raising field is constantly changed to modernization pasture, and it is subject to the attention of all sectors of society day by day on the impact of surrounding enviroment protection, improves milk cow grassland environment; particularly deal carefully with grassland wastes, become the difficult problem faced by modernization pasture.The COD of grassland wastes, particularly cow dung, ox urine, NH
3-N and P content all very high.Must process, otherwise will the severe contamination of environment be caused.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and is urinated fermentative production fertilizer by cow dung, polluted to solve it, improves the technique of economic worth simultaneously.
To achieve these goals, a kind of organic fertilizer production technique, includes following steps:
1) cow dung urine is sent into anaerobically fermenting pond, continuously ferment 48 hours;
2) the cow dung urine after fermentation is sent into extruding tripping device, obtain dry cow dung and the waste water of moisture about 55-60%;
3) step 2 gained waste water is sent into methane-generating pit process;
4) step 3 gained is done cow dung and cripple, chicken manure, microbiobacterial agent and the straw powder weight ratio Homogeneous phase mixing according to 6.5:1:1:0.0000105:1.5;
5) mixture step 4 obtained loads fermenter, and controlling leavening temperature is 55 ~ 65 DEG C, and fermentation time keeps at least 72 hours;
6) fertilizer that step 5 obtains is transported to stacking canopy, carries out normal temperature Secondary Fermentation, fermentation time remains 15 ~ 20 days summer and autumns, winter-spring season 20 ~ 25 days;
7) fertilizer step 6 obtained carries out drying, pulverizing, screening and packaging.
Preferably, in order to prevent growing grass and the blocking of other foreign material water pump, pipeline, valve and its structures in material, material removes foreign material by stirring cutting pump before carrying out step 1).
Preferably, in order to ensure carrying out smoothly of fermentation, improve ferment effect, the water content of the cripple of step 4) is 80%, and the water content of chicken manure is 15%.
The organic fertilizer production technique tool of technique scheme is adopted to have the following advantages: 1) due to cow dung urine has been carried out separating dry space from moist space, waste liquid is sent into methane-generating pit separately, not only avoid pollution, and containing N, P, K and Macro and microelements in biogas fermentation debris, and nutritive substance and the physiologically active substance such as amino acid, VITAMIN, protein, Plant hormones regulators,gibberellins, growth hormone, carbohydrate, nucleic acid, be the necessary nutritive ingredient of plant growth, biological growth and output increased can be promoted.Contain a large amount of humic acid substance in the slag of natural pond simultaneously, to improvement soil, there is good effect; 2) due to by dry cow dung and cripple, chicken manure, microbiobacterial agent and the straw powder weight ratio Homogeneous phase mixing according to 6.5:1:1:0.0000105:1.5, carry out again once obtaining fertilizer with Secondary Fermentation, quality index can reach: organic total content >=45%, below moisture content≤30%, total nutrient >=5%, meet the requirement of agricultural industry criteria " organic fertilizer quality standard " (NY525-2012), the fertilizer after process can be widely used in the ground such as Vegetable Base, Garden Greenland and golf course.Cow dung can not produce harmful effect to environment after Organic Fertilizer Plants process.
Embodiment
The invention provides a kind of organic fertilizer production technique, include following steps:
1) by cow dung urine through stirring cutting pump process, remove the foreign material growing grass and wait and easily block water pump, pipeline, valve, afterwards by cow dung urine feeding anaerobically fermenting pond, normal-temperature continuous is fermented 48 hours;
2) the cow dung urine after fermentation is sent into extruding tripping device, obtain dry cow dung and the waste water of moisture about 55-60%;
3) step 2 gained waste water is sent into methane-generating pit process;
4) step 3 gained is done cow dung and cripple, chicken manure, microbiobacterial agent and the straw powder weight ratio Homogeneous phase mixing according to 6.5:1:1:0.0000105:1.5;
5) mixture step 4 obtained loads fermenter, and controlling leavening temperature is 55 ~ 65 DEG C, and fermentation time keeps at least 72 hours;
6) fertilizer that step 5 obtains is transported to stacking canopy, carries out normal temperature secondary aerobic fermentation, fermentation time remains 15 ~ 20 days summer and autumns, winter-spring season 20 ~ 25 days;
7) fertilizer step 6 obtained carries out drying, pulverizing, screening and packaging.
Wherein the water content of the cripple of step 4) is 80%, and the water content of chicken manure is 15%.
The organic fertilizer technique index that obtains of step 7 is as following table on inspection:
| Project | Index |
| Organic content (in butt)/% | ≥45 |
| Total nutrient (nitrogen+Vanadium Pentoxide in FLAKES+potassium oxide) content (in butt)/% | ≥5 |
| Moisture (free-water) content/% | ≤30 |
| Potential of hydrogen | pH 5.5~8.0 |
The fertilizer that step 7 obtains is used in vast farmland, can play improvement Soil structure, increases crop yield, improves cash crop market sale price.Adopt organic fertilizer production technique of the present invention can solve pasture cow dung process problem, and play treatment for cow manure system infusion of financial resources recovery, improve social benefit, increase the object of economic benefit.
Above-described is only certain preferred embodiments of the present invention; it should be pointed out that for a person skilled in the art, under the prerequisite not departing from instant component proportioning and processing parameter; can also make some improvement, these also should be considered as protection scope of the present invention.
