Description

Technical Field

[0001] The invention relates to the field of bio-organic fertilizer production, in particular to an environmentally friendly production method of tank-type bio-organic fertilizer. Background Art

[0002] In the intensive breeding of poultry such as chickens, ducks, and geese, a large amount of feces will inevitably be produced. If a large amount of biological feces is directly discharged into the environment, it will seriously cause environmental pollution. In order to effectively utilize the above-mentioned biological feces, most of the biological feces on the market are now fermented so that the biological feces can be turned into organic fertilizer, thus turning waste into conservation.

[0003] However, the common fermentation treatment nowadays is usually open-type, and its external environmental conditions such as temperature and humidity are poorly controllable, making it difficult to ensure that the activity of microorganisms can meet the requirements, resulting in poor quality of the biological organic fertilizer produced, long fermentation time and low economic benefits.

[0004] In order to ensure effective control of the fermentation environment, tank processing is often used. Both biological manure and microorganisms can be placed in sealed tanks to facilitate the regulation of the fermentation environment and reduce the interference of the external environment on the fermentation process. However, in the current tank organic fertilizer production, there are still many problems such as excessive moisture in the biological manure, insufficient activity and quantity of bacterial strains, which leads to unstable production capacity of biological organic fertilizer and weak market competitiveness. Summary of the invention

[0005] The object of the present invention is to provide a tank-type bio-organic fertilizer environmentally friendly production method, which can solve one or more of the above problems.

[0006] According to one aspect of the present invention, there is provided a tank-type bio-organic fertilizer environmentally friendly production method, comprising the following steps:

[0007] Step a, taking fresh feces, auxiliary materials and bacterial strains, mixing the fresh feces, auxiliary materials and bacterial strains to obtain seed feces, and mixing them every 15m 3 ~25m 3 The fresh feces is mixed with 45m 3 ~55m 3 of auxiliary materials and 8kg to 12kg of bacterial strains;

[0008] Step b, taking a fermentation tank, adding seed manure into the fermentation tank, the volume ratio of the seed manure input to the volume of the fermentation tank is 60-80:100, hot air is continuously introduced into the fermentation tank to maintain the internal temperature of the fermentation tank at 60°C-75°C, and the seed manure is intermittently stirred, and the fermentation is continued for 3-7 days, the first intermittent stirring is 25 minutes-35 minutes each time, and the interval between two adjacent stirrings is 40 minutes-60 minutes;

[0009] Step c, taking fresh feces and auxiliary materials, mixing the fresh feces and auxiliary materials to obtain conventional feces, 3 ~12m 3 The fresh feces is mixed with 1m 3 ~2m 3 The auxiliary materials are used to obtain conventional feces, wherein the moisture content of the conventional feces is 60% to 65%;

[0010] Step d, adding conventional manure into the fermentation tank after step b every day, and continuing for 5 to 7 days, and at the same time, continuously introducing hot air into the fermentation tank to maintain the internal temperature of the fermentation tank at 60° C. to 80° C., and performing a second intermittent stirring on the conventional manure, wherein the second intermittent stirring is performed for 25 to 35 minutes each time, and the interval between two adjacent stirrings is 40 to 60 minutes, and the daily ratio of the input volume of the conventional manure to the volume of the fermentation tank is 10 to 13:100, and the fermentation is continued for 5 to 7 days to obtain organic fertilizer;

[0011] Step e: After step d, 5 m3 can be taken out from the fermentation tank every day. 3 ~6m 3 of organic fertilizer, and add 10m 3 ~13m 3 During the period between the input of new conventional manure and the next extraction of organic fertilizer, hot air is continuously introduced into the fermentation tank to maintain the internal temperature of the fermentation tank at 60°C to 80°C, and a third intermittent stirring is performed at the same time, wherein each stirring time of the third intermittent stirring is 25 minutes to 35 minutes, and the interval between two adjacent stirrings is 40 minutes to 60 minutes.

[0012] The beneficial effects of the present invention are as follows: in the present invention, by first putting in seed manure, setting the fermentation tank at a specific temperature, and adding sufficient air into the fermentation tank, the strains can be cultivated conveniently, and in the fermentation process of each step, intermittent stirring is required to facilitate the strains to have enough time to be in a static environment for reproduction, so as to jointly ensure that the strains have sufficient quantity and activity. The ratio of fresh feces and auxiliary materials in conventional feces is obtained through a large number of experiments, which can effectively ensure that the water content of the conventional feces put into the fermentation tank is within a specific range, and the conventional feces has a suitable carbon-nitrogen ratio, so that it can be better fermented into organic fertilizer. The method of forming organic fertilizer is environmentally friendly and effective, with a short fermentation time, high economic benefits, and strong reliability.

[0013] In addition, the daily amount of organic fertilizer taken out and supplemented in the present invention is also obtained through a large number of experiments, which can ensure that the conventional manure after supplementation has little effect on the taken out organic fertilizer after 1 day, thereby ensuring the quality of the taken out organic fertilizer and preventing excessive removal from causing insufficient colonies.

[0014] In some embodiments, the auxiliary material is one or more of wood chaff, corn cobs or straw.

[0015] In some embodiments, in step c, after the fresh feces and the auxiliary materials are stirred and mixed, they are stacked for 1 day. When the water content of the fresh feces is too high, it is still difficult to make the water content meet the requirements by simply mixing with the auxiliary materials. Stacking for one day can effectively reduce its water content, so as to ensure that the water content of the conventional feces meets the requirements.

[0016] In some embodiments, in steps b, d and e, fermentation gas is generated in the fermentation tank, and the fermentation gas can be discharged after heat exchange, filtration and deodorization in sequence, thereby effectively reducing the pollution and impact of the fermentation gas on the environment, further improving the environmental friendliness of the method.

[0017] In some embodiments, the heat energy obtained by the heat exchange is used in steps b, d and e. Thus, the heat in the post-fermentation gas can be reused, energy waste can be reduced, and the economic benefits of the method can be improved.

[0018] In some embodiments, step e comprises supplementing the fermenter with 10 m 3 ~13m 3Before adding the conventional manure, the organic fertilizer in the fermentation tank is stirred for 50 to 70 minutes. Since most fermentation tanks rely on gravity to take out materials, and the fermented materials have a certain viscosity, after the fermentation tank takes out materials, the feeding position will form a vacant space in a short time. If the material is added immediately, the newly added conventional manure may accumulate in the vacant space. Since the feeding position of the fermentation tank is often fixed, a large amount of organic fertilizer with insufficient fermentation time may be obtained when taking out materials again the next day, resulting in unsatisfactory quality of the obtained organic fertilizer.

[0019] In some embodiments, the bacterial species include one or more of Bacillus subtilis, Bacillus amyloliquefaciens, Saccharomyces cerevisiae, and Aspergillus niger, and include one or more of cellulase and protease. BRIEF DESCRIPTION OF THE DRAWINGS
