Dead-of-disease livestock and poultry harmless and recycling treatment method

Abstract

The invention discloses a dead-of-disease livestock and poultry harmless and recycling treatment method. The method includes following steps: classifying and registering livestock and poultry corpses of free-range farmers and in livestock and poultry farms after registration and tabulation; freezing and transporting the corpses in a unified manner after registering to a treatment center for pretreatment like dismemberment and disinfection; using a disintegrator to disintegrate dead-of-disease livestock and poultry corpses during treatment; putting the disintegrated corpses into a drying room, using hot gas at temperature of 120-320 DEG C to directly sterilize and dry, and enabling grease flowing out in the process of sterilizing and drying to flow into a grease collection tank; squeezing substances like meat, hair and bone after being sterilized; enabling grease obtained in the process of squeezing to flow into the collection tank while enabling sewage generated in the process of oil-water separation to flow into biological purifying equipment for purifying; conveying meat and bone residue obtained after separation into a biological fermentation tank for fermentation. The method is low in energy consumption, high in recycling degree and low in wastewater yield, wastewater and waste gas can be treated well, and the technical problems of large sewage treatment quantity and high treatment difficulty in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of resources and environmental protection, in particular to a method for harmless and resourceful treatment of sick and dead livestock and poultry. Background technique [0002] Harmless disposal of sick and dead animals is an important measure to prevent the spread of animal diseases, effectively control and exterminate animal diseases, and prevent pathogens from polluting the environment. Since the 1980s, due to the frequent occurrence of major animal diseases such as foot-and-mouth disease, mad cow disease, and highly pathogenic avian influenza, society has paid more and more attention to the harmless disposal of animal carcasses. my country is a big country in poultry and livestock breeding, and its breeding scale ranks among the top in the world. During the breeding process of poultry and livestock, there is a certain mortality rate due to weather, epidemic diseases and other reasons. For dead poultry ...

AI Technical Summary

Problems solved by technology

There are expensive facilities, heavy labor, high demand for fuel, affected by weather and environment, it is difficult to get public support, and it is not suitable for handling the carcasses of transmissible spongiform encephalopathy-infected animals

Fermentation treatment method is adopted, because the fermentation tank takes up a lot of land and the fermentation cycle lasts for more than 100 days, a strong odor is emitted within hundreds of meters around the fermentation tank, which seriously pollutes the surrounding environment, and the capacity of the fermentation tank is limited. The number of diseased poultry and livestock to be accommodated is not large, and once a plague occurs, it will be difficult to handle
