Animal harmless treatment: promoting resource utilization of animal waste and environmental protection

Animal waste refers to animal carcasses, feces and waste generated during agricultural livestock and poultry breeding, slaughtering and processing, scientific research and experiments. In traditional treatment methods, animal waste is often buried or conventionally treated, which is prone to environmental pollution and health risks. In order to solve these problems, animal harmless treatment came into being. This article will introduce the concept, main methods and application value of animal harmless treatment, aiming to emphasize its importance to resource recovery and environmental protection. 1. The concept of animal harmless treatment Animal harmless treatment refers to the process of making animal waste harmless, resource-based or reused through a series of treatment processes. Through appropriate treatment methods, harmful substances in animal waste are removed or transformed to achieve a state that is harmless to the environment and realize efficient use of resources. 2. Main methods of animal harmless treatment 1. Environmental control: Control the generation and discharge of waste by strengthening the environmental management of animal farms. Including the reasonable setting of breeding facilities, strengthening the construction of waste treatment areas, preventing direct discharge of waste, and reducing environmental pollution and the spread of infectious diseases. 2. Anaerobic digestion: Anaerobic digestion is the process of decomposing and fermenting animal wastes such as feces to produce biogas and organic fertilizers through the action of microorganisms. Using biogas to generate electricity and biogas slurry for fertilization can achieve resource recovery and energy utilization. 3. Harmless composting: Using appropriate composting technology, by controlling temperature, humidity and ventilation, the organic matter in animal waste can be decomposed into stable organic fertilizer. Harmless composting can convert waste into organic fertilizer, reducing the waste of land resources and the use of chemical fertilizers. 4. Thermochemical treatment: Animal waste is treated through the action of high temperature and chemical agents. For example, the high temperature melting method can treat animal carcasses at high temperatures to convert them into harmless bone meal and oil, realizing resource recovery and reuse. 5. Biotransformation: Biotransformation is the use of bioengineering technology, such as the action of microorganisms, to degrade and transform animal waste. For example, the ability of insects, such as black ants and flies, can be used to quickly degrade animal carcasses to achieve effective resource utilization. III. Application value of harmless treatment of animals 1. Environmental protection: harmless treatment can effectively reduce the pollution of animal waste to the environment, reduce the risk of soil, water and air pollution, and protect the stability of the ecological environment. 2. Resource recovery: harmless treatment of animals can convert waste into reusable resources such as organic fertilizers and biogas, reduce resource waste, and promote the development of circular economy. 3. Economic benefits: Through the harmless treatment of animal waste, organic fertilizers, biogas and other products that can be used for agricultural production and energy supply can be obtained, increasing the economic benefits of agriculture and energy. 4. Reducing the risk of infectious diseases: harmless treatment of animals can effectively control the spread of infectious diseases, prevent pathogens from entering the environment and food chain, and protect public health and animal health. Harmless treatment of animals converts animal waste into resources and achieves harmlessness of waste, which is of great significance to environmental protection and resource recovery. Through environmental control, anaerobic digestion, harmless composting, thermochemical treatment and biological transformation, the impact of animal waste on the environment and health can be effectively reduced, and sustainable development can be promoted. When implementing harmless animal treatment, we need to pay attention to legality and standardization, comply with local laws and regulations, and ensure process safety and environmental friendliness. At the same time, we need to strengthen the public's environmental awareness and assume social responsibility, and jointly promote the resource utilization of animal waste and environmental protection.
