Description

Reaction kettle treatment process for animals died of diseases
Technical Field
The invention belongs to the technical field of environmental protection, and particularly relates to a reaction kettle treatment process for animals died of diseases.
Background
With the rapid development of modern breeding industry, large-scale breeding is achieved, and great progress is made, but as large-scale animal farms are continuously enlarged and the breeding amount is gradually increased, the death rate of livestock is high due to the influence of factors such as breeding management, nutrition level, epidemic disease prevention and treatment technology, immune stress reaction and the like, and a large amount of dead animal bodies are generated. Because small and medium-sized farms and household farmers do not have special corpse treatment facilities for animals died of illness, the corpses are randomly discarded in roadside ditches, and even some farmers discard the animals died of illness at low price in order to reduce loss. The mode of processing the animal carcasses died of illness not only influences the environmental sanitation and pollutes soil, water sources and air, but also causes the diffusion of virus and bacteria along with the putrefaction and the rot of the animal carcasses died of illness and even the variation due to the influence of the environment, thereby causing a new animal epidemic source, bringing the loss which is difficult to estimate to the animal husbandry in China, and seriously harming the health of people and livestock and the healthy development of economic construction. Dead animal carcasses become the seeder for people and livestock suffering from diseases, and become fire seeds of epidemic situations.
In the process of raising livestock and poultry breeding enterprises, a certain number of animals die due to various reasons, and in the process of transporting and producing meat products, meat food slaughtering and processing enterprises die due to physical death caused by extrusion, high temperature and the like, and the number of the animals is incredible. Each processing enterprise and the breeding industry have respective harmless treatment processes, and some irregular scattered farmers with small scale cannot achieve the requirement of large-scale production and cannot carry out harmless treatment according to the requirement, so that the phenomenon of stealing and throwing away occurs. In 2013, a large amount of dead pigs are surprised on Huangpu river in China, and the whole country is wondered. In order to standardize harmless treatment of animals died of illness, effectively prevent and control major animal epidemic diseases, ensure the safety of animal breeding environment and ensure the quality safety of animal products, according to the animal epidemic prevention law of the people's republic of China, the national Ministry of agriculture issues the technical standard of harmless treatment of animals died of illness about 2013, 10 and 15 days, the harmless treatment refers to the process of treating animal carcasses died of illness by physical and chemical methods, eliminating pathogens carried by the animal carcasses and eliminating the harm of the animal carcasses, the following four methods are specifically guided:
1. the burning method comprises the following steps: the animal carcasses and related animal products or broken products are fed into a combustion chamber of the incinerator body, the high-temperature flue gas generated after full oxidation and pyrolysis enters a secondary combustion chamber for continuous combustion, and the generated slag is discharged through a slag extractor. The flue gas at the outlet of the secondary combustion chamber is treated by a waste heat utilization system and a flue gas purification system and then is discharged after reaching the standard. The incineration slag and the incineration fly ash collected by the dust removal equipment are collected, stored and transported respectively. Treating the incinerator slag according to common solid waste; the incineration fly ash and other solid wastes collected by the tail gas purification device are treated as hazardous wastes if the solid wastes belong to hazardous wastes.
2. Burying method:
(1) direct burying method: the place with high and dry terrain and downwind direction should be selected. The volume of the pit body is determined by the number of animal carcasses and related animal products actually processed. The bottom of the burying pit is higher than the underground water level by more than 1.5m, and is required to be impermeable and leakproof. Spraying a layer of disinfectant such as quicklime or bleaching powder with the thickness of 2-125px on the pit bottom. And putting the animal carcasses and related animal products into the pit, wherein the distance from the uppermost layer to the ground surface is more than 1.5 m. Sterilizing with disinfectant such as calx or bleaching powder. Covering the soil with a thickness of not less than 1-1.2m and a distance of 20-750px from the ground surface.
(2) Cellaring a corpse: the corpse cellar of the livestock and poultry farm is combined with the characteristics of the field shape and is suitable to be built in the downwind direction. The chemical dead body cellar is of a sealing structure of bricks and concrete or reinforcing steel bars and concrete, and should be impermeable and leak-proof. A throwing port is arranged at the top, and a cover is covered, sealed and double-locked; odor removal devices such as odor adsorption and filtration are arranged. Before putting, a certain amount of quicklime or disinfectant should be spread at the bottom of the chemical corpse cellar. After placing, the placing opening is sealed, covered and locked, and the placing opening, the corpse cellar and the surrounding environment are disinfected. When the carcass reaches three quarters of the volume in the carcass cellar, it should be taken out of service and sealed.
3. A fermentation method: the fermentation pile structure mainly comprises a strip pile type and a fermentation tank type. Before treatment, 500px thick auxiliary materials are paved at a designated place or the bottom of a fermentation tank. Animal carcasses or related animal products are flatly laid on the auxiliary materials, and the thickness of the auxiliary materials is less than or equal to 500 px. The 500px of dressing is covered to ensure that the carcass or related animal products are completely covered. The thickness of the stack is determined by the number of animal carcasses to be treated and related animal products and is generally controlled to be between 2 and 3 m. The internal temperature of the compost fermentation pile is more than or equal to 54 ℃, the pile is turned after one week, and the operation is finished after 3 weeks. The auxiliary materials are mixture of rice chaff, sawdust, straws, corncobs and the like, or products obtained by adding specific biological agents into the mixture of the rice chaff, the sawdust and the like and performing pre-fermentation.
In the four processing methods: the incineration method inevitably generates greenhouse effect in the incineration process and emits the greenhouse effect to the atmosphere; if the harmless treatment on the dead animal carcasses is not thorough and standard, not only can the spread of epidemic diseases be caused to cause environmental pollution, but also the safety of animal food is extremely easily harmed, and even the healthy and stable development of social economy is influenced;
