Correct understanding of the difference between an ectopic fermentation bed and a dry distiller?
First, the process is different.
The comprehensive pollution control technology of ex situ fermentation bed is a new achievement for the harmless treatment of manure. It allows farmers to raise pigs in the traditional way without rebuilding or demolition of pig farms. It only builds fermentation tanks where the potential of the pig site is low. The manure is evenly sprayed on the fermentation bed, and the pollutants are degraded by microbial fermentation to achieve zero emission of pollution and biological organic fertilizer is obtained.
The piggery waste flows from the pipeline into the collection tank, and is cut and stirred by the cutting pump and the mixer to ensure that the waste is not delaminated. The sewage is evenly sprayed on the litter by an automatic spraying device. Next, the manure will be subject to biodegradation treatment by the microbial flora. During the degrading process, the automatic turning machine also turns the fermentation bed, promotes the pig manure and urine to fully mix, and finally converts the pig manure into bio-organic fertilizer, thus realizing the resource utilization of the pollutants.
The dry-sauce fermentation bed aquaculture technology is a major improvement aimed at the living environment of economic animals. It aims to improve the quality of meat products and achieve zero pollution. This technology is a disruptive change to traditional farming techniques. Using this breeding method, it is necessary to lay around 50 centimeters of litter on the bottom of the house and mix high-efficiency compound beneficial bacteria into the litter. This species can efficiently decompose the waste. The direct conversion of excreta into non-polluting carbon dioxide and water. This method is used for breeding, without cleaning manure, no odor in the enclosure, soft and comfortable noodles, and the quality of life of animals is greatly improved, and zero pollution and zero emissions are achieved at the same time. The matted litter deposits rich urine decomposition products, which are extremely valuable for fertilizers and are ideal raw materials for organic fertilizers.
Second, the difference in the core starting point.
The starting point of the two is different. The former aims to reduce the impact of breeding on the human living environment, but there is no substantial improvement for animals. The latter is aimed at improving the living environment of animals and at the same time realizing the improvement of human living environment.
The ectopic fermentation bed does not change the traditional culture method, but improves the handling mechanism of cultured urine. Therefore, its core starting point is the treatment of excreta. This method uses the decomposition of microorganisms to achieve the harmless treatment of excreta, and the final product of the treatment is a very good raw material for organic fertilizers. Pollution problems.
The dry-sanding fermentation bed is a change to the subversive nature of traditional culture. Its core starting point is to improve the living conditions of animals. The core of this method is to lay a thick litter on the ground of the pens. The litter is mainly composed of sawdust and the bacteria that spread among them. The litter is not only to improve the comfort of animal life, but also the rich microbes can The animal's excreta is directly decomposed and there is no need to worry about the secondary pollution caused by the accumulation of excreta. The origin of the method actually simulates the functional characteristics of the land of nature. Nature's land is soft and comfortable, and it can degrade feces, which is very suitable for animal survival. The fermentation bed is built on this basis. Through artificial optimization, the risk controllability is greatly improved, and the natural state can be achieved without increasing the risk of breeding. .
Third, the difference in practical applications.
The ex-situ fermentation bed is a great upgrade and improvement of the excreta treatment system, and the excreta handling capacity and excreta disposal results have all greatly changed. The most important thing is that this method does not affect the daily aquaculture production activities. It only needs to set up new facilities on the original basis. From the aspect of operability, it is very easy to operate. However, the method requires high equipment. If the scale of breeding is too small, the relative cost of excreta disposal will be greatly increased, so this method is suitable for large-scale farms. For small-scale farms, there are still irreconcilable contradictions.
The dry spreader bed can greatly improve the quality of meat products and is an ecological farming method. This method does not require the introduction of auxiliary equipment relative to the ectopic fermentation bed, so the investment is relatively low. However, because of the lack of auxiliary equipment and its binding with animals, the ability to treat excreta is not exorbitantly strong. Therefore, there is a high requirement for the culture density and the activity of the bacteria. The density density of the culture is only 70% of the traditional culture density, and the activity requirement of the strain is higher than that of the ectopic fermentation bed. Comprehensively speaking, for small-scale farmers, dry spreader beds are undoubtedly the better choice. It not only reduces investment, but also produces high-quality meat. It is also a good choice for large-scale farms.
Fourth, the versatility of strains is different.
The types of bacteria in the ectopic fermentation bed and the dry-sanding fermentation bed are all aerobic. This type of bacteria is more efficient than anaerobic decomposition and is suitable for the decomposition of fecal urine. However, in terms of versatility, the ectopic fermentation bed strains are not easy to use on dry fermentation beds, and dry-sown fermentation beds have a higher requirement for the activity and profitability of the strains because the litter is in direct contact with the animals. Kind must be harmless and helpful. The ectopic fermentation bed is slightly lower in strain requirements, so the use of ectopic fermentation bed strains on a dry-sweeping fermentation bed can easily cause poor fermentation bed operations. Conversely, it is feasible to use dry yeast strains in the ex-situ fermentation bed, which of course is feasible and can improve the original treatment efficiency.
to sum up
Both methods have their merits, and how to choose them depends on the needs. For example, the purpose of production, consumer demand for the consumer, the size of the farm, the location of the farm, the requirements for environmental protection, etc. Farming is risky. Please be cautious when you are on the line. If you have to do this line, you should learn more about it from the technical staff. Avoid ideas and practices that are taken for granted.
