At the same time, the chicken's digestive tract is short, the feed stays in it for a short time, and a considerable part of the nutrients in its excreted feces are not digested and utilized by the body, which has caused a waste of food resources.

Embodiment Construction
[0025] see Figure 1 to Figure 5 Shown, the concrete steps of the present invention are as follows:
[0026] 1. Organic fertilizer production process
[0027] 1.1 Stacking of chicken manure (generally, the moisture content of chicken manure should be controlled at about 75%);
[0028] 1.2 Add 2‰ strains and 4‰ FeSO 4 After collecting 15% bran (calculated by fresh chicken manure), turn it over twice with a throwing machine to fully mix the chicken manure;
[0029] 1.3 Cover with plastic film and carry out anaerobic fermentation (fermentation time: 3 days in summer and 5 days in winter);
[0030] 1.4 After the anaerobic fermentation is completed, the plastic film is uncovered for aerobic fermentation. During the aerobic fermentation, 8 times of turning and throwing machine turning is performed every day (15 days of aerobic fermentation in winter and 12 days of summer);
[0031] 1.5 After the aerobic fermentation is completed, the material is fully decomposed and the moistur...

The invention relates to a method for preparing an organic compound fertilizer by treating chicken manure through biological fermentation technology, which comprises the following steps: a, putting the chicken manure of which the moisture content is 70 to 75 percent to a place requiring fermentation; b, adding a proper amount of strains, FeSO4 and rice mill by-product into the chicken manure in the step a and fully mixing; c, coating a plastic film on the chicken manure after uniformly mixing in the step b for anaerobic fermentation; d, uncovering the plastic film for aerobic fermentation after the anaerobic fermentation in the step c is completed; e, completing the aerobic fermentation, fully decomposing the material, controlling the moisture to between 45 and 50 percent, transferring toa drying room for drying, and making the moisture of the material after the drying lower than 20 percent; and f, taking the dried material as a semi-finished product of the organic compound fertilizer. The method utilizes a whole set of process technology for treating the chicken manure through industrial biofermentation for the first time, provides scientific basis for treating the chicken manure on the spot of large farms, and solves the pollution problem of the chicken manure; and the production scale of the technology can be amplified or reduced.
Description
technical field [0001] The invention relates to a method for producing organic compound fertilizer by using biological fermentation technology to process chicken manure. Background technique [0002] After the 1980s, the number of chickens in my country increased rapidly, and the number of chickens in stock ranked first in the world. It contributed to solving the supply of eggs and chicken in people's lives and helping farmers increase their economic income. But, along with the development of modern intensive chicken industry, in addition to producing a large amount of meat, egg products, also brought a series of problems, especially the output of a large amount of chicken farm waste, wherein chicken manure is chicken farm The most important pollutant in the environment and the largest source of pollution in the surrounding environment. Chicken manure contains a large number of pathogenic microorganisms, organic substances and heavy metals (copper, zinc, manganese, etc.). ...
