Innocent treatment process for livestock and poultry died from diseases

Abstract

The invention relates to an innocent treatment process for livestock and poultry died from diseases. The innocent treatment process comprises the following steps: disinfecting a transport vehicle; breaking livestock and poultry died from diseases, metering and weighing the broken materials, and then carrying out high-temperature and high-pressure sterilization treatment; collecting waste gas generated during the high-temperature and high-pressure sterilization treatment, removing a small amount of materials contained in the waste gas, condensing the waste gas obtained by separation, introducing the condensed waste gas into a biofilter and filtering; performing coarse filtering, namely, performing solid-liquid separation on a mixture of material and oil after high-temperature and high-pressure sterilization treatment, and storing the separated oil into an oil storage tank; performing refined filtering, namely, performing solid-liquid separation on the material obtained by solid-liquid separation again, and storing the separated oil into the oil storage tank; performing oil separation, namely, performing solid-liquid separation on the oil in the oil storage tank, so as to obtain high-purity oil which can be taken as bio-oil for production, wherein the separated tiny material is subjected to refined filtering again; and finally, grinding the material obtained after solid-liquid separation and bagging. According to the innocent treatment process, resource utilization is realized, waste is turned into valuable, energy is saved, and the environment protection purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment, in particular to the treatment technology for sick and dead pigs and other livestock and poultry. The invention provides a harmless treatment process for sick and dead livestock and poultry. Background technique [0002] In 2013, the incident of nearly 6,000 dead pigs fished out of the Huangpu River in Shanghai was widely circulated among the public, which shocked the whole society. It also raised people's thoughts on how to treat sick and dead pigs harmlessly, how to turn waste into treasure, The requirements for the harmless treatment of dead livestock and poultry stipulated by the Ministry of Agriculture are strictly in accordance with the "Disposal Methods of Animals with Unknown Causes of Death" and "Biosafety Treatment Regulations for Diseased Animals and Diseased Animal Products". In the chemical treatment, the more widely used and more mature technologies mainly...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: (1) it is easy to pollute the groundwater source; (2) due to rain and flood, the rotting animal carcasses may be exposed to the wild again; (3) the profits may be stolen by mercenaries

The disadvantages of this method are: (1) large investment; (2) high operating cost; (3) limited processing capacity; (4) harmful gas needs to be reprocessed

The disadvantages of this method are: (1) There are many process links, and the waste water cannot be discharged directly and needs to be reprocessed; (2) The treatment cycle is long and energy consumption

[0007] At present, the treatment devices and methods for diseased poultry and livestock are to treat animal carcasses as garbage, which does not give full play to the intrinsic value of diseased poultry and livestock. How to continue to develop the intrinsic value of diseased poultry and livestock and carry out secondary development and utilization, It is of great significance to save resources and protect the environment
