Method for harmlessly treating plague-infected animal tissues

Abstract

The invention discloses a method for harmlessly treating plague-infected animal tissues by using an alkaline hydrolysis mode. The method comprises the following steps: (1) weighing plague-infected animal tissues, and putting the plague-infected animal tissues into a reaction container; (2) adding water and alkali into the reaction container in proportions; (3) heating the reaction container, firstly performing stirring-free alkaline hydrolysis to soften the tissues, and then performing hydrolysis while stirring to crush the tissues; (6) dehydrating and condensing a hydrolysis product; and (7) discharging the product, and recycling. By adopting the method disclosed by the invention, vast majority of pathogenic microorganisms can be inactivated, sterilization and decomposition processes can also be completed, and secondary operations can be avoided; air and water cannot be polluted in an implementation process of the method, and high biological safety can be achieved; and a dehydration product can be taken as a biological fertilizer or a compost additive, and the recycling utilization of resources can be achieved.

Description

technical field [0001] The invention relates to the technical field of a method for treating animal tissues infected with epidemics, and more specifically, relates to a method for harmlessly treating animal tissues infected with epidemics by using alkali hydrolysis. Background technique [0002] my country is a country with a relatively high mortality rate of livestock and poultry. A large number of infected animal carcasses have potential hazards such as spreading diseases, threatening food safety, and polluting the environment. Traditional disposal methods include direct burial, incineration, and oil refining. Unable to completely inactivate pathogenic microorganisms, occupy land, and pollute the underground environment; although the incineration method thoroughly treats animal carcasses, it will emit harmful gases such as dioxins during the incineration process, which will bring a lot of pollution to the air; the oil refining method requires special Refining equipment, and ...

Problems solved by technology

[0002] my country is a country with a relatively high mortality rate of livestock and poultry. A large number of infected animal carcasses have potential hazards such as spreading diseases, threatening food safety, and polluting the environment. Traditional disposal methods include direct burial, incineration, and oil refining. Unable to completely inactivate pathogenic microorganisms, occupy land, and pollute the underground environment; although the incineration method thoroughly treats animal carcasses, it will emit harmful gases such as dioxins during the incineration process, which will bring a lot of pollution to the air; the oil refining method requires special Refining equipment, and the refining process cannot kill some pathogens such as prions, so the scope of use is limited

[0003] In addition, my country's biosafety laboratories have also developed common treatment methods for experimental animal slices, organs, and corpses containing pathogenic microorganisms, but they also have their own shortcomings: the current conventional high-pressure sterilization treatment at a temperature of 121 ° C and a time of 30 minutes It is impossible to guarantee that infected animal tissues are thoroughly sterilized and need to be transported to other locations for decomposition. The sterilization and decomposition processes of animal tissues are carried out separately, which increases the risk and cost of transportation and secondary treatment
