Embodiment 1

[0034] 1. Configuration of basic materials

[0035] Basic material composition: by weight percentage, 50% cow dung + 30% straw powder + 10% peat + 9% lignite + 0.5% ferrous sulfate + 0.5% zinc sulfate, mixed evenly to adjust the moisture content to 55% %, C / N was adjusted to 27:1, and the pH was adjusted to 7.8 with an appropriate amount of lime; 0.2% CM fermentation agent (produced by Shandong Yi'an Bioengineering Co., Ltd.) was 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 every 24 hours for 7 to 10 days. When the compost temperature drops to 41°C (no longer rising), 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 to 10 days, spread out in the air for a while, disperses and reduces the moisture in the compost material to make t...

Embodiment 2

[0046] (1) Take the organic waste from the cattle farm, add dry crop rice bran in a weight ratio of 4:3 to the rice bran, mix evenly, and adjust the moisture content to 50%, and adjust the C / N to 25:1, Adjust the pH to 7.5;

[0047] (2) In the above mixture, in terms of weight percentage, evenly add 0.2% organic waste fermentation koji (produced by Beijing Jingpuyuan Biological Engineering Co., Ltd.) to ferment, that is, compost ripening, fermentation conditions: temperature 45°C , Oxygen 0.2m 3 / min, the time is 7-8 days, after 36 hours of fermentation, turn the pile, and then turn it every 24 hours;

[0048] (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;

[0049] (4) Turn the above-mentioned compost and pile it up again, and carry out secondary fermentation for 9 to 10 days at a temperature of 35°C to distribute and reduce the moisture in the compost material so that the moisture conten...

Embodiment 3

[0052] (1) Take the organic waste from the cattle farm, add dry crop straw powder in a weight ratio of 6:3 to the straw powder, mix evenly, and adjust the moisture content to 60%, and adjust the C / N to 30: 1. Adjust the pH to 8.0;

[0053] (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 ferment, that is, compost ripening, fermentation conditions: temperature 60 ° C, oxygen content 0.15 m 3 / min, the time is 9 days, after 36 hours of fermentation, turn the pile, and then turn the pile every 24 hours;

[0054] (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;

[0055] (4) Turn the above-mentioned compost and pile it up again, and carry out secondary fermentation for 7 to 8 days at a temperature of 40°C to dissipate and reduce the moisture in the compost material to make its m...

Abstract

The invention discloses a fertilizer-generating method using organic waste of cattle farm, which comprises the following steps: adjusting ratio of C / N and moisture; adding aerobic fermenting organism preparation; treating the mixture with aerobic fermentation, second fermentation and disintegration; adding macro-element fertilizer or micro-element chemical fertilizer and modifier of fertilizer or vegetation; granulating and getting organic fertilizer or organic-inorganic compound fertilizer. The invention has property of convenient method, can treat organic waste in cattle farm one time; and products fertilizer with flexible nutrient ratio, high adaptability and significant production-increase effect.

Description

technical field [0001] The invention relates to a method for producing fertilizer, in particular to a method for producing fertilizer by using organic waste from cattle farms. Background technique [0002] With the development of economy, animal husbandry has changed from sideline business to main business, and its output value accounts for the proportion of large agricultural output value increasing year by year, more than 50%. However, the problem of environmental pollution caused by a large amount of excrement produced in the process of animal husbandry and the loss of livestock and poultry manure has been placed in front of us very urgently. How to reasonably and effectively use and deal with livestock and poultry manure has aroused widespread concern and is urgently needed. solved problem. [0003] Livestock and poultry manure is directly applied as organic fertilizer, and its biggest obstacle is high water content and foul odor. In addition, NH 3 A large amount of vo...
