Description

Rendering system for treating excavated dead animals in carcasses-burried area}

The present invention relates to a rendering system for processing an excavated carcass in a livestock burial site, and more specifically, after crushing a livestock burial excavation carcass, as it matures with high-temperature steam, it improves the separation efficiency of remnants and liquids. , It relates to a rendering system for the treatment of livestock buried excavations, which can sterilize infectious microorganisms, as well as environmental pollution caused by contaminants generated in conventional burial excavations.

In general, when an epidemic such as foot-and-mouth disease and avian influenza occurs, the livestock is disposed of, and so far, it has mainly relied on incineration or burial treatment methods.

Incineration is a method that removes various environmental problems caused by the investment and incinerates at an incinerator of 800°C or higher as a sanitary and safe treatment method to reduce the volume and weight and recycle it to landfill or compost.

However, the incinerator must be installed separately for incineration, and the installation is reluctant due to cost burden, periodic inspection, and complaints, and the actual operating rate is extremely low due to fuel costs.

Also, depending on the type of the object and the state of its content, the incineration method may not be able to achieve complete combustion. During the combustion process, unburned substances, dust, pathogens and severe odors are discharged into the atmosphere, causing the second environmental pollution. It is presented as a problem.

On the other hand, burial is a method of spraying quicklime and then covering it with soil after digging a pit of a certain depth on the ground surface and then putting animal carcasses.

This burial method is difficult because it is difficult to secure an appropriate site, labor is required, and it is easy to cause disinfection and complaints due to odor, soil and water pollution.

In particular, due to the problem of post-leaching, the treatment cost due to odor and groundwater contamination is not perfect even though it is astronomically required.

Therefore, in order to solve these problems, install a water repellent for leachate leakage in the investment pit before investing the animal, or in an animal waste container made of synthetic resin, as disclosed in Korean Patent Registration No. 20-0457078, as a disposal treatment device. And then use the method of burying the pit in the pit.

In this case, anaerobic conditions are formed due to the poor circulation of air inside the burial site (pit or burial box), and decomposition of the carcass is mainly caused by anaerobic microorganisms. During this process, a large amount of odor and leachate are generated and pollute the surrounding environment. Order.

In particular, the leachate is not discharged to the outside, and as the dead body is locked inside the investment site, the dead body is prevented from coming into contact with the air to further strengthen the anaerobic conditions.

Therefore, in order to solve this problem, it is necessary to excavate the debris from the animal's magazine and go through the incineration process again, but as described above, an incinerator must be installed separately, and it is difficult to adopt due to cost burden, periodic inspection, and complaints.

Accordingly, there is an urgent need to develop a technology capable of preventing and minimizing recycling and environmental pollution of resources by improving the treatment efficiency of the disposed animals and using the by-products obtained after treatment as a raw material for compost or biodiesel. It is becoming.
