Harmless treatment method of pigs died from diseases

Abstract

The invention discloses a harmless treatment method of pigs died from diseases. The harmless treatment method comprises the following steps of: carbonizing, extracting, and carrying out prefermentation and fermentation, cleaning and crushing the pigs died from diseases, and then carrying out high-temperature and high-pressure carbonization to prepare oil and residue; after the oil is extracted, obtaining industrial oil; carrying out mixed fermentation on prefermented rice bran, wood dust, cotton stalks and corncobs with carbonized residue of the pigs died from diseases and calcium superphosphate to obtain fertilizer. The harmless treatment method disclosed by the invention has the beneficial effects that flue gas is adsorbed and dedusted after quenching and deacidification, and finally isexhausted after reaching the standard; after the pigs died from diseases are treated by high-temperature and high-pressure carbonization, the oil is separated from protein, bone and phospholipid and the like, so that no pollution is generated to the environment; due to the prefermentation step, the fermentation efficiency can be improved, the treatment time of the pigs died from diseases can be shortened, and the loss of nitrogen can be reduced; meanwhile, the pigs died from the diseases are transformed into the fertilizer with strong fertility, so that not only is the ecological environment protected, but also wastes can become valuables, and the economic value can be increased.

Description

technical field [0001] The invention relates to the field of treatment of sick and dead livestock, in particular to a harmless treatment method for sick and dead pigs. technical background [0002] Affected by traditional breeding habits, the concept of modern animal husbandry is not publicized enough, and there are few comprehensive supporting measures for animal husbandry with facilities. Animal carcasses and slaughter waste pollution produced by animal husbandry in some places have caused serious damage to the livestock and poultry breeding environment, human settlements, and living environment. Very dangerous. The random discarding of livestock and poultry waste has become an urgent problem to be solved, and it is also a major issue of energy saving and emission reduction in the country. [0003] At present, the application of recycling technology in most livestock farms mainly focuses on the prevention and control of poultry manure and sewage pollution, but there are n...

However, the base layer of the litter in this inventive method has not been sterilized or fermented, which will lead to the growth of harmful microorganisms in the litter, which will cause wasteful corruption of pork. In this inventive method, the whole pig is stacked and fermented, which will take time If it is too long, the treatment process in the inventive method can reach 120-180 days, which seriously reduces the efficiency of harmless treatment of sick and dead pigs
