Problems solved by technology

Both deep burial and incineration do not consider resource utilization, resulting in a great waste of high-grade organic material resources. The treatment company has no economic benefits, and it is difficult to obtain a long-term mechanism. Moreover, deep burial also has the risk of polluting shallow water and groundwater , incineration will increase the content of PM 2.5 in the atmosphere and pollute the atmosphere
The production of organic fertilizer after high-temperature and high-pressure cooking takes into account the issue of resource utilization. However, due to the low price of organic fertilizer products and the high cost of high-temperature and high-pressure cooking, the economic benefits of enterprises are still very low, and it is difficult to operate in an enterprise
The direct production of organic fertilizer by biological fermentation takes into account resource utilization issues. Although the production cost is low, the maximum temperature of biological fermentation is only 75°C, which makes it difficult to kill pathogenic bacteria. Frequent turning and throwing of composting may cause the spread of pathogenic bacteria in the air. It is unacceptable to pollute the environment

Embodiment 1

[0036] Example 1 A harmless treatment method for sick and dead livestock and poultry animals, which is characterized in that it is treated according to the following process steps:

[0037] (1) In a closed container, the sick and dead livestock and poultry animals are automatically crushed, and all solids and liquids are automatically transferred to a closed hydrolysis tank. Hydrolysis under 1 atmosphere pressure for 2 hours;

[0038] (2) After the hydrolysis is completed, when the solution in the hydrolysis tank is cooled to below 80°C, use the energy to enter and exit the feeding port of the hydrolysis tank to float and stand upright.

[0039] The vacuum suction device on the grease separates the upper layer of grease;

[0040] (3) After the oil is separated, slowly add hydrogen oxygen into the hydrolysis tank according to the mass ratio of hydrolyzate and potassium hydroxide at 4:1.

[0041] Potassium chloride, stirring while adding, adjust the pH value of the solution to...

Embodiment 2 Embodiment 1

[0044] Embodiment 2 According to embodiment 1, process according to the following process steps:

[0045] (1) In a closed container, the sick and dead livestock and poultry animals are automatically crushed, and all solids and liquids are automatically transferred to a closed hydrolysis tank. Hydrolysis at 2 atmospheres for 5 hours;

[0046] (2) When the hydrolysis is completed and the solution in the hydrolysis tank is cooled to below 80°C, use a vacuum suction device that can enter and exit the feed port of the hydrolysis tank to float and stand upright on the grease to separate the upper layer of grease;

[0047] (3) After the oil is separated, slowly add potassium hydroxide into the hydrolysis tank according to the mass ratio of the hydrolyzate and potassium hydroxide at 4:1, and stir while adding to adjust the pH value of the solution to 3; The mass ratio of shells or crab shells is 10:3. Add lobster shells or crab shells to the hydrolyzate, raise the temperature to 80°C...

Abstract

The invention discloses a harmless treatment method for livestock and poultry dying of illness. The method comprises the steps that firstly, the livestock and poultry dying of the illness are automatically crushed, all solid matter and liquid are sealed and hydrolyzed, heat preservation hydrolysis is carried out for 1 hour under the initial acid concentration c(1 / 2H2SO4) of 2mol / L-1 at 121 DEG C, and then upper-layer grease is separated when the temperature of hydrolysates is decreased to be below 80 DEG C; and the pH value of the hydrolysates is adjusted to be 1-3, and an amino acid solution is collected through primary precipitation or secondary precipitation by adopting a natural precipitation method. According to the method, new pollution cannot be generated to the environment, and harmless treatment of the livestock and poultry dying of the illness can be realized.

Description

technical field [0001] The invention relates to zero-pollution and harmless treatment of sick and dead livestock and poultry animals and high value-added resource utilization technology. [0002] It belongs to agricultural intensive production technology. Background technique [0003] my country produces about 450 million tons of fresh and live commercial livestock and poultry animals every year. Based on the normal mortality rate of 5% in large-scale livestock and poultry breeding and the dead weight of 30% of the time of sale, my country produces about 6.6 million tons of fresh dead animals every year In recent years, the state has strictly prohibited and strengthened the efforts to crack down on the entry of sick and dead animals into food. For a time, incidents of sick and dead animals littering and seriously polluting the environment often occurred. Background technique [0004] my country produces about 450 million tons of fresh and live commercial livestock and po...
