Embodiment 1

[0031] Embodiment one: the method for the harmless treatment of dead animals due to epidemic diseases, comprising the following steps:

[0032] The first step: After the dead animals are frozen and crushed, the oil is steamed at high temperature, and the oil is recycled, that is, initial sterilization and oil recovery:

[0033] (1) Firstly, collect and transport sick and dead animal residues in strict accordance with GB16548-2006 Biosafety Treatment Regulations for Diseased Animals and Diseased Animal Products, and freeze and crush the animal residues (material particle size ≤ 70cm, which is conducive to more sufficient and rapid subsequent biodegradation ).

[0034] (2) Put the crushed animal remains into the container, heat and stir, carry out initial sterilization, recover the steamed oil, and use the remaining materials in the next step.

[0035] The second step: disinfection and sterilization again, biodegradation reaction

[0036] Add the remaining material after the i...

Embodiment 2

[0042] Example 2: Resource Utilization—Preparation of Organic Fertilizer or Organic-Inorganic Compound Fertilizer

[0043] After the detoxification treatment in Example 1, the animal remains have been completely decomposed into powdery residues, which contain a large amount of minerals in addition to a large amount of organic amino acids. The composition of various minerals in the animal body is shown in Table 2, wherein calcium, Phosphorus accounts for 65% to 75%. According to the analysis of the empty body composition (excluding the content of the digestive tract) of 18 steers of different ages, the average content of the main mineral elements is shown in Table 2.

[0044] Table 2 Contents of animal residues

[0045] .

[0046]In addition to the above mineral elements, it also contains trace amounts of Fe, Cu,  Zn, Mn, Co, Se, Mo, F, Ni, V, Sn, Si, As and other 15 elements, which are essential nutrients for crop growth Elements or beneficial elements are high-quality ra...

Embodiment 3

[0069] Embodiment three: fertilizer field test

[0070] Using the organic-inorganic compound fertilizer obtained in Example 2, a wheat-corn rotation field test was carried out at the field test base in Xiangfulu Village, Jiulong Town, Zhongmu Town.

[0071] General situation of the test site: The soil of the test site is sandy fluvo-aquic soil developed on the aeolian deposits of the old course of the Yellow River. See Table 6 for the organic matter and available nutrient contents of nitrogen, phosphorus and potassium in the 0-40 cm plow layer of the test site.

[0072] Table 6 Soil nutrient content of the test site

[0073] .

[0074] Experimental design: There are 3 treatments in this experiment, and the dosages are: K1: no fertilizer application; K2: application of 100 kg of traditional compound fertilizer per mu; K3: application of 100 kg of organic-inorganic compound fertilizer per mu; % and jointing stage topdressing 40% applied twice. Wheat basal fertilizer was so...

Abstract

The invention discloses a harmless treatment and resource utilization method for animals died of epidemic situation. The problems that in the prior art, harmless treatment of animals died of epidemic diseases is not thorough, and low-cost resource utilization is difficult are solved. The method comprises the following steps: freezing and crushing animal residues, heating, stirring, carrying out primary sterilization on the materials, recovering evaporated grease, feeding the residual materials into a harmless treatment tank, carrying out secondary sterilization at high temperature and high pressure, recovering grease, adding an efficient biological composite treatment agent, and carrying out biodegradation. The obtained residues are prepared into an organic fertilizer or an organic-inorganic compound fertilizer by a non-drying method. According to the method disclosed by the invention, a physical and biochemical combined method is comprehensively adopted, the frozen and crushed animal residues are fully sterilized, disinfected and biodegraded, and the product subjected to innocent treatment is used as an organic raw material for preparing an organic fertilizer or an organic-inorganic compound fertilizer, so that resource recycling is realized, and the method is safe, environment-friendly and relatively low in operation cost.

Description

technical field [0001] The invention relates to the technical field of resource recovery and utilization, in particular to a method for harmless treatment and resource utilization of animals that died of an epidemic. Background technique [0002] Animal carcasses, especially those with unknown causes of death, are extremely dangerous. Severe infectious diseases and poisons are likely to be hidden in these carcasses. If they are not handled or handled improperly, they will spread and spread. Some farmers even sell diseased and dead animals at low prices to reduce losses, resulting in the indirect flow of diseased and dead animals to the dining table through various channels. After eating, people can be directly infected by pathogens or harmed by toxins, threatening human life. The decay and deterioration of the corpses of sick and dead animals will not only pollute the air, but also pollute the soil and water sources, causing serious ecological and environmental hazards. ...
