Innocent treatment method of converting dead pig into fertilizer

Abstract

The invention relates to an innocent treatment method of converting a dead pig into a fertilizer, and belongs to the technical field of intensive agricultural production. The method comprises the following steps: (1) slitting, (2) mincing, (3) fermentation, (4) sterilization and (5) sieving. According to the preparation method, the organic fertilizer is prepared by utilizing the dead pig, and fishbone, rice bran powder or a plant straw and a traditional Chinese medicine component are added, so that the content of calcium salt and a mineral substance in the organic fertilizer is increased; the organic fertility is improved; insect generation of the organic fertilizer in sieving and composting processes is avoided; an insect prevention effect of the fertilizer is improved; the method has the significant benefits.

Description

Technical field [0001] The invention relates to a harmless treatment method for returning fat from dead pigs, and belongs to the technical field of agricultural intensive production. Background technique [0002] Pork is my country's main meat consumption species, and the pig industry has a pivotal position in my country's agricultural production and animal husbandry production. From an international perspective, my country’s pig farming and pork consumption account for about half of the global total, ranking first in the world, which is vital to the development of the global pig industry. According to the survey, the treatment of sick and dead pigs in small-scale pig farms in my country is mostly in a disorderly state. Some are purchased and then wholesaled or processed to be sold in the market. Some are simply discarded due to difficulties in handling, and some are incompletely burned or deep-fired. Burial, causing great hidden dangers to livestock and poultry food safety and a...

Problems solved by technology

[0003] Among them, the high-temperature carbonization method is the pyrolysis and carbonization of animal carcasses. It is a high-temperature harmless process that uses high temperature to crack the organic components in animal carcasses, release volatile products and form solid carbonized products under anaerobic conditions. Treatment technology, the odor produced by incineration is difficult to deal with, the cost is high, and the later operation is difficult, which will pollute the atmosphere; the chemical method is divided into two types: drying and humidification. The drying method: put the sick and dead livestock and poultry into the drying machine Inside, the hot steam does not directly contact the sick and dead livestock and poultry, and kills the virus by heating the shell of the chemical machine. It is easy to produce malodorous gas and waste water, which has a great impact on the surrounding environment and high operating costs in the later period. The mechanical fermentation method is to add auxiliary materials to support organic fertilizers by mechanically crushing the materials, which has little impact on the environment. However, due to the difference in auxiliary materials and production processes , there are also differences in the organic fertilizer products made
