Problems solved by technology

But because of its slow harmless process, it may pollute the soil or groundwater
In addition, this law does not apply to the treatment of infected animals, products and tissues
(2) Incineration method: refers to stacking dead livestock and poultry on enough fuel or placing them in an incinerator to achieve complete combustion and carbonization of livestock and poultry carcasses in the shortest time, but a large amount of pollutants (smoke) will be produced during the process. gas), and at the same time, if there is incomplete combustion of organic matter in the combustion process, it will pollute the environment
(3) Composting of animal carcasses: refers to placing animal carcasses inside the compost and degrading the animal carcasses through the metabolic process of microorganisms, but it may cause the spread of pathogenic microorganisms, and at the same time pollute the composting equipment and even infect composting personnel
However, the existing chemical hydrolysis and enzymatic treatment process is prone to produce malodorous gas (obvious odor) and waste water

Abstract

The invention discloses a technological method for innocent treatment of animals dying from diseases through subcritical water. The technological method includes the steps that crushed animal carcasses are sealed after the addition of purified water; the animal carcasses are put at the temperature of 170-240 DEG C and the pressure of 0.5-3.6 Mpa, and the temperature and the pressure are kept for certain time; preferably, the temperature and the pressure are kept for 1-2 hours. According to the technological method for innocent treatment of the animals dying from diseases through subcritical water, the animals dying from diseases and waste of the animals are used, and therefore various liquid amino acid with high yield can be prepared through the method. The technological method is low in cost, convenient to implement and simple, the environment and the waste are utilized, and the technological method is worthy of being popularized greatly.

Description

technical field [0001] The invention relates to the technical field of harmless treatment of dead animals, in particular to a method for harmless treatment of dead animals with subcritical water. Background technique [0002] Dead animals, as a substitute raw material for fossil raw materials, have attracted more and more attention because of their wide range of resources and renewability. "Currently expired dead animals are treated as waste." At present, in the harmless treatment of sick and dead livestock and poultry, the technologies that are widely used mainly include deep burial, incineration, composting, cadaver pit treatment, chemical production, biodegradation and other treatment methods. (1) Deep burial method: refers to making use of the self-purification function of the soil to make it harmless by burying it. But because of its slow harmless process, it may pollute the soil or groundwater. In addition, this law does not apply to the treatment of infected animals...
