Problems solved by technology

The advantages of anaerobic treatment are: the odor of the final product of the treatment is reduced, and the methane gas produced can be used as energy. The disadvantage is: NH 3 There is a lot of volatilization loss, the volume of the treatment tank is large, and it can only be treated and utilized on site; the treatment of manure in the aerobic oxidation tank is to use natural microorganisms to convert organic matter into carbon dioxide and water under aerobic conditions.
[0005] Among them, returning livestock and poultry manure to the field as an organic-inorganic compound fertilizer after composting and fermenting is the most convenient and economical way to process and utilize it. However, the traditional natural composting method is not only time-consuming for duck manure resources, but also the fermentation temperature is not high. Difficult to kill a large number of insect hatching and germs contained in feces
[0006] At present, most duck manure resources are not utilized or anaerobic fermentation is adopted. The disadvantages of anaerobic fermentation are: NH 3 There is a lot of volatilization loss, the volume of the treatment pool is large, and it can only be treated and utilized on site
The operation of this method is relatively complicated and not suitable for the objective situation in China
At present, there is no method for the secondary fermentation of duck manure resources using bacterial agents for high-temperature composting

Embodiment 1

[0033] 1. Configuration of basic materials

[0034] Basic material composition: by weight percentage, 50% duck manure + 30% straw powder + 10% peat + 9% lignite + 0.5% ferrous sulfate + 0.5% zinc sulfate are mixed evenly to adjust the moisture content to 55% %, C / N is adjusted to 27:1, and the pH is adjusted to 7.8 with an appropriate amount of lime; 0.2% CM fermentation agent (produced by Shandong Yi'an Bioengineering Co., Ltd.) is evenly added by weight percentage. Pile it into a strip with a width of 4 meters and a height of 1.5 meters for fermentation. After 36 hours, turn over. Afterwards, turn the compost once every 24 hours for 7-10 days. When the compost temperature drops to 41°C (no longer rises), and the C / N drops to 17:1, and the pH drops to 6.7, the primary fermentation is completed. . The fermented material is subjected to secondary fermentation for 7-10 days, spread out in the air for a while, disperses and reduces the moisture in the compost material so that ...

Embodiment 2

[0045] (1) Using duck manure resources, add dry rice bran in a weight ratio of 4:3 to rice bran, mix evenly, and adjust the moisture content to 50%, adjust the C / N to 25:1, and adjust the pH to 7.5;

[0046] (2) In the above mixture, in terms of weight percentage, evenly add 0.2% CM fermentation bacteria agent (produced by Shandong Yian Biological Engineering Co., Ltd.) to carry out aerobic fermentation, that is, compost ripening, fermentation conditions: temperature 45 ° C, oxygen Volume 0.2m 3 / min, the time is 7-8 days, after 36 hours of fermentation, turn the pile, and then turn the pile every 24 hours;

[0047] (3) When the compost temperature drops to 40°C, and the C / N drops to 16:1, and the pH drops to 6.0, the compost ripening is completed;

[0048] (4) Turn the above-mentioned compost and pile it up again, and carry out secondary fermentation for 9-10 days at a temperature of 35°C to dissipate and reduce the moisture in the compost material so that the moisture cont...

Embodiment 3

[0051] (1) Utilize duck manure resources, add dry crop straw powder in a weight ratio of 6:3 to straw powder, mix evenly, and adjust its moisture content to 60%, C / N to 30:1, pH Adjust to 8.0;

[0052] (2) In the above mixture, in terms of weight percentage, evenly add 0.2% CM fermentation bacteria agent (produced by Shandong Yian Biological Engineering Co., Ltd.) to carry out aerobic fermentation, that is, compost ripening, fermentation conditions: temperature 60 ° C, oxygen Volume 0.15m 3 / min, time 9 days, ferment for 36 hours, turn over the pile, after that, turn over once every 24 hours;

[0053] (3) When the compost temperature drops to 42°C, and the C / N drops to 20:1, and the pH drops to 6.3, the compost ripening is completed;

[0054] (4) Turn the above-mentioned compost into piles and pile up again, and carry out secondary fermentation for 7-8 days at a temperature of 40°C to distribute and reduce the moisture in the compost material to make its moisture content 30%...

Abstract

The invention discloses a method for producing an organic and inorganic compound fertilizer by utilizing a duck dropping source, which comprises the following steps: regulating C / N ratio and water content of organic wastes; adding a CM fermenting agent to the organic wastes; carrying out aerobic fermentation and secondary fermentation on the organic wastes and then pulverizing the organic wastes; adding large and intermediate trace element chemical fertilizers and a fertilizer regulator or a plant growth regulator to the pulverized organic wastes; and granulating to prepare a commercial organic fertilizer. The invention has simple method, can process the duck dropping source at a time and has flexible nutrient proportioning and strong adaptability of the produced organic fertilizer and obvious fertilizer yield increasing effect.

Description

technical field [0001] The invention relates to a fertilizer production method, in particular to a method for producing organic-inorganic compound fertilizer by utilizing duck manure resources. Background technique [0002] With the development of the economy, the livestock and poultry industry has changed from a sideline industry to a main industry, and the ratio of its output value to the large agricultural output value is increasing year by year, exceeding 60%. However, the large amount of excrement produced in the process of livestock and poultry breeding and the problem of environmental pollution caused by the loss of livestock and poultry manure have been placed in front of us very urgently. How to reasonably and effectively use and deal with livestock and poultry has aroused widespread concern and needs to be solved urgently. question. [0003] Livestock and poultry manure is directly applied as an organic-inorganic compound fertilizer. The biggest obstacle is high w...
