Biological degradation method and degradation device for animal carcasses

Abstract

The invention discloses a biological degradation method and degradation device for animal carcasses. The degradation method comprises the following steps of 1 raw material smashing, wherein animal carcass raw materials needing to be treated are smashed into blocks through a smashing machine; 2 high-temperature sterilizing and one-time degrading, wherein the smashed animal carcass raw materials are conveyed into a decomposition tank, high-temperature sterilizing bacteria and auxiliary materials for adsorbing oil and fat are added into the tank, then the decomposition tank is sealed and heated to 120 DEG C or above, stirring is performed in a timing mode in the heating process, standing is performed for 10-14 hours, and then the materials are discharged; 3 secondary degrading, wherein composting fermentation is performed on the animal carcass raw materials processed through high-temperature sterilizing and one-time degrading to complete secondary degrading. According to the method, sterilizing is safe and thorough, sterilizing, decomposing and waste gas condensing and recycling of the animal carcasses are achieved at a time in the decomposition tank, the application range is wide, produced organic fertilizer cannot damage crops, the technology is reasonable, operation is easy and convenient, and energy conversation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment of animal corpses, in particular to a biodegradation method and a degradation device for animal corpses. Background technique [0002] Animal carcass refers to the complete or partial body of a dead animal, including animal viscera and scrap meat. In a broad sense, animal carcasses should include the complete or partial bodies of all dead animals, not only domesticated livestock and poultry, special farmed animals, but also wild animals and even various insects. Animal carcasses, regardless of whether they died normally or died of epidemic diseases, often carry a variety of germs. If they are not handled or handled properly, the carcasses will quickly decompose and rot and emit odors, causing pathogenic microorganisms to pollute the air, water and soil, resulting in the spread of diseases and People who have direct or indirect contact with it at the same time may be inf...

Problems solved by technology

But at present, this treatment method is not yet mature, and there are still application misunderstandings, the process is unstable, and there are still problems such as incomplete fermentation and damage to crops.
