Embodiment 1

[0022] A harmless and environmentally friendly treatment method for dead pigs, comprising the following steps:

[0023] (1) Disinfection treatment: use superheated steam to disinfect the sick and dead pigs for 2 hours;

[0024] (2) Cultivate fermentation auxiliary materials: prepare a mixture of wood bran and wheat bran in the fermentation tank, keep the relative humidity at 60%, put in thermophilic bacteria, and mix well;

[0025] (3) Heat exchange: A heat exchanger is installed in the fermentation tank, so that the condensed water generated during the disinfection of sick and dead pigs enters the heat exchanger, and the temperature of the material in the tank is heated to 65°C;

[0026] (4) Fermentation treatment: Put the sterilized sick and dead pigs into the fermenter, mix them evenly with the fermented material mixture, keep the temperature in the tank at 65°C, and ferment for 15 hours to obtain organic fertilizer raw materials.

[0027] The superheated steam in step (1)...

Embodiment 2

[0034] A harmless treatment method for dead pigs, comprising the following steps:

[0035] (1) Disinfection treatment: use superheated steam to disinfect the sick and dead pigs for 1.5 hours;

[0036] (2) Cultivate fermentation auxiliary materials: prepare a mixture of wood bran and wheat bran in the fermentation tank, keep the relative humidity at 70%, put in thermophilic bacteria, and mix well;

[0037] (3) Heat exchange: A heat exchanger is installed in the fermentation tank so that the condensed water generated during the disinfection of sick and dead pigs enters the heat exchanger, and the temperature of the material in the tank is heated to 72°C;

[0038] (4) Fermentation treatment: Put the sterilized sick and dead pigs into the fermenter, mix them evenly with the fermented material mixture, keep the temperature in the tank at 72°C, and ferment for 12 hours to obtain organic fertilizer raw materials.

[0039] The superheated steam in step (1) has a temperature of 115°C ...

Embodiment 3

[0046] (1) Disinfection treatment: use superheated steam to disinfect the sick and dead pigs for 1 hour;

[0047] (2) Cultivate fermentation auxiliary materials: prepare a mixture of wood bran and wheat bran in the fermentation tank, keep the relative humidity at 80%, put in thermophilic bacteria, and mix well;

[0048] (3) Heat exchange: A heat exchanger is installed in the fermentation tank, so that the condensed water generated during the disinfection of sick and dead pigs enters the heat exchanger, and the temperature of the material in the tank is heated to 80°C;

[0049] (4) Fermentation treatment: Put the sterilized sick and dead pigs into the fermenter, mix them evenly with the fermented material mixture, keep the temperature in the tank at 80°C, and ferment for 10 hours to obtain organic fertilizer raw materials.

[0050] The superheated steam described in step (1) has a temperature of 120° C. and a pressure of 2.0 MPa.

[0051] The thermophilic bacteria described in...

Abstract

A harmless environment-friendly processing method for diseased dead pigs comprises the following steps: disinfection processing, concretely, performing disinfection processing on diseased dead pigs for 1-2 h by utilizing hot water steam; culture of fermentation auxiliary material, preparing a mixture of sawdust and wheat bran in a fermentation tank, keeping the relative humidity to be 60-80%, pouring a thermophilic bacterial strain, and uniformly mixing; heat exchange, concretely, arranging a heat exchanger in the fermentation tank, enabling condensing water generated when diseased dead pigs are disinfected to enter the heat exchanger, and keeping the temperature of the material in the fermentation tank to be 65-80 DEG C; and fermentation processing, concretely, putting the disinfected diseased dead pigs into the fermentation tank, uniformly mixing with the fermentation mixture, keeping the temperature in the tank to be 65-80 DEG C, and fermenting for 10-15 h, so as to obtain an organic fertilizer raw material. The method is simple, small in land occupation area, short in processing time and high in energy utilization rate, and realizes harmless environment-friendly processing of diseased dead pigs.

Description

technical field [0001] The invention relates to a harmless and environment-friendly treatment method for sick and dead pigs. Background technique [0002] In recent years, with the growing demand of the people, the number of pig farms in our country has also continued to increase. Even with high-level management, pig farms cannot avoid encountering sick and dead pigs. Sick and dead pigs can spread and spread diseases, which will not only cause economic losses, but also pollute the environment and threaten the health of humans and animals. Therefore, safe and effective means should be adopted to deal with sick and dead pigs. At present, the commonly used methods for dealing with sick and dead pigs are: (1) incineration, which will produce toxic and harmful gases, pollute the environment, and consume a lot of energy, resulting in waste of resources; (2) landfill, which occupies a large area , After the dead pigs are corrupted, harmful gases and liquids leak out, which will po...
