Embodiment 1

[0036] Embodiment 1, dead poultry harmless treatment method:

[0037] according to figure 1 The flow chart shown is for the treatment of sick and dead livestock:

[0038] 1) First, use a crusher to crush the sick and dead poultry and livestock into materials with basically the same size, and then transport the materials to the thermal hydrolysis reactor;

[0039] 2) Feed saturated steam into the thermal hydrolysis reactor, and control the hydrolysis conditions: the temperature is 150-170°C, the pressure is 0.5-0.8 MPa, and the hydrolysis is carried out for 40-120 minutes under the above conditions, so as to treat sick and dead poultry and livestock. Fully sterilized to achieve harmlessness, and at the same time, the thermal hydrolysis step can effectively destroy the tissue structure of dead poultry and livestock corpses, causing the water inside the tissue to overflow, which is more conducive to the follow-up treatment of sick and dead poultry and livestock; after thermal hy...

Embodiment 2

[0043] Embodiment 2, the harmless treatment method of dead poultry and livestock:

[0044] according to figure 1 The process shown deals with the treatment of sick and dead livestock.

[0045] 1) First, use a crusher to crush the sick and dead poultry and livestock into materials with basically the same size, and then transport the materials to the thermal hydrolysis reactor;

[0046] 2) Feed saturated steam into the thermal hydrolysis reactor, and control the hydrolysis conditions: the temperature is 170-220 ° C, the pressure is 0.8-1.6 MPa, and the hydrolysis is carried out for 40-100 minutes under the above conditions, so as to treat sick and dead poultry and livestock. Fully sterilized to achieve harmlessness, and at the same time, the thermal hydrolysis step can effectively destroy the tissue structure of dead poultry and livestock corpses, causing the water inside the tissue to overflow, which is more conducive to the follow-up treatment of sick and dead poultry and liv...

Embodiment 3

[0050] Embodiment 3, the harmless treatment method of dead poultry and livestock:

[0051] according to figure 1 The process shown deals with the treatment of sick and dead livestock.

[0052] 1) First, use a crusher to crush the sick and dead poultry and livestock into materials with basically the same size, and then transport the materials to the thermal hydrolysis reactor;

[0053] 2) Feed saturated steam into the thermal hydrolysis reactor, and control the hydrolysis conditions: the temperature is 200-220 °C, the pressure is 1.6-2.3 MPa, and the hydrolysis is carried out for 30-80 minutes under the above conditions, so as to treat sick and dead poultry and livestock. Fully sterilized to achieve harmlessness, and at the same time, the thermal hydrolysis step can effectively destroy the tissue structure of dead poultry and livestock corpses, causing the water inside the tissue to overflow, which is more conducive to the follow-up treatment of sick and dead poultry and lives...

Abstract

The invention discloses an innocent treatment method of dead livestock, which comprises the following steps: 1) breaking the dead livestock to form a broken material, and hydrolyzing the broken material to form a clinker, 2) carrying out solid-liquid separation on the clinker obtained in Step 1) to form slurry, and 3) carrying out anaerobic digestion on the proceed obtained in Step 2) to achieve the purpose of innocent and resourceful treatment of the dead livestock. The treatment method effectively achieves stabilization, innocuousness and reduction of the dead livestock, thoroughly stabilizes unstable organic substance, produces methane, water and the like, causes no secondary pollution and can be further matched with a biogas slurry and biogas residue treatment system to effectively achieve organic substance reduction of the dead livestock; the methane generated after the anaerobic digestion can serve as high quality clean energy; solid residue after pressing can also be disposed reasonably according to specific circumstances; at the same time, contact between a livestock corpse and a human body and spreading of pathogenic bacteria are avoided; and the method is easy to implement, manage and popularize.

Description

technical field [0001] The invention belongs to the field of treatment and resource utilization of sick and dead poultry and livestock, and in particular relates to a harmless treatment method of sick and dead poultry and livestock. Background technique [0002] According to the regulations in the "Biosafety Treatment Regulations for Diseased Animals and Diseased Animal Products GB 16548-2006", dead poultry and livestock generally include: 1) infected animals and their products; 2) animal carcasses that died of disease, poison or unknown cause; 3 ) Diseased animals and diseased animal products that have been tested to be toxic and harmful to humans and animals and need to be destroyed; 4) Other animals and animal products that should be destroyed as stipulated by the state. [0003] Livestock carcasses not only carry a large number of bacterial viruses, but also contain a large amount of nutrients and are prone to breed bacteria. Improper handling will cause serious harm to ...
