Technical Field
The invention belongs to the field of environmental treatment, and particularly relates to a biodegradable fermentation bed and application thereof.
Background
In recent years, the breeding industry of China is rapidly developed, and the breeding level is improved year by year. However, even in modern-scale farms, there are still a certain number of dead birds. The phenomenon that pigs died due to illness are discarded at will is disclosed in China in the report of the pigs died due to floating in rivers in east China. The dead livestock and poultry bodies are not only discarded at will, but even illegal vendors sell the dead livestock and poultry.
Taking the pig as an example, the death number of the live pig in the city of Qinzhou in 2013 is 56900 according to statistics. Due to the lack of animal carcass harmless treatment technology, the phenomenon that the pigs died of illness are still discarded in the peripheral area of the city of Qinzhou. The pigs died of the disease harbor a plurality of pathogenic microorganisms, particularly pathogenic bacteria which are common to people and livestock, and the pigs are easy to cause diseases and even die after being contacted with people. Therefore, pigs died of disease are often the effective treatment for spreading and expanding the disease. The harmless treatment of animals died of illness is also an important measure for guaranteeing public safety.
In developed areas of the east coast, large-scale farms dispose of animal carcasses using large incinerators to incinerate the carcasses. The incinerator can be used for harmless treatment of animal carcasses, has the advantages of high efficiency, rapidness, thorough incineration and capability of effectively killing pathogenic microorganisms and preventing pigs dead from being sold on the market. However, the incineration equipment is high in price and difficult to maintain, and is difficult to popularize and use in small and medium-sized farms.
In order to reduce costs, some large farms often dispose of animal carcasses in landfills. However, the degradation speed of the animal carcasses is slow under natural conditions, and a large amount of land and an excavator are needed for landfill, so that the method is not a long-term measure for the treatment of the animal carcasses.
Therefore, a biodegradable fermentation bed is urgently needed in society.

the application of the biodegradable fermentation bed in degrading the animal carcasses is also within the protection scope of the invention.
The operation steps for degrading the animal carcasses by using the product of the invention are as follows:
(1) solarizing the biogas residues and the edible fungus residues for 7-10 days, and crushing for later use;
(2) fully mixing yeast freeze-dried powder, bacillus subtilis freeze-dried powder, the crushed biogas residues obtained in the step (1) and the crushed edible fungus residues obtained in the step (1) to obtain a degradation matrix for later use;
(3) filling the degraded matrix obtained in the step (2) into the matrix layer of the fermentation bed, and setting the rest layers; after the preparation is finished, spraying a ripener into the fermentation bed, and after 5-10 days, the biodegradable fermentation bed can be used for degrading animal carcasses;
(4) and (4) spraying a potassium oxalate aqueous solution on the surface of the animal carcass to be degraded, burying the animal carcass to the degradation matrix of the fermentation bed treated in the step (3), and finishing degradation after 7-12 days.
In the step (3), the solvent of the ripener is water, and the solutes are glucose and ethanol; wherein the volume fraction of solute ethanol is 15%, and the mass fraction of solute glucose is 5-9%.
In the step (3), the weight ratio of the ripener to the degradation matrix is 1: 10 to 15.
