Collection system: firstly, an effective collection system needs to be designed, which can collect methane in cow farts in dairy farms in a large area. It can be considered to collect the cow fart into the gas collection chamber or gas collection tank by pipeline, and then compress the gas through the compressor and transport it to the treatment facility. In addition, specific enzymes can be added to feed to help reduce methane production.
Treatment facilities: The treatment facilities may include a methane purification system to purify the collected gas into high-concentration methane for energy production or other purposes. The system can use existing technologies, such as gas separation, adsorption, condensation, etc.
Energy utilization: methane can be used to produce energy, such as power generation or as fuel. We can consider building a micro-energy plant on the farm, using biogas as the main fuel to meet the energy demand of the farm. In addition, methane can also be transported to nearby energy facilities for utilization.
Long-term storage: If methane cannot be used in time, long-term storage can be considered. For example, methane can be injected into underground strata for storage, or it can be converted into other chemicals for storage.
It should be noted that environmental protection and safety issues need to be considered when implementing the system. For example, it is necessary to ensure that the collection system will not have a negative impact on the health and environment of dairy cows, and at the same time, it is necessary to comply with relevant safety standards and regulations to ensure the safety of operation.
In addition, in order to improve efficiency and sustainability, the following aspects can be considered:
Optimizing feed: By optimizing feed formula, methane emission of dairy cows can be reduced. For example, you can choose low-emission feed raw materials or add specific additives, such as organic minerals and microbial agents.
Feeding management: By improving feeding management methods, methane emission of dairy cows can be reduced. For example, controlling the feeding density reasonably, keeping the pens well ventilated, and cleaning the feces regularly are all helpful to reduce the generation and emission of methane.
Scientific and technological innovation: through scientific and technological innovation, we can develop more efficient and environmentally friendly collection and utilization technologies. For example, more efficient methane purification technology, storage technology and biomass energy utilization technology can be developed.
Policy support: The government can provide relevant policy support to encourage aquaculture to take measures to reduce methane emissions. For example, tax incentives, subsidies, incentives and other measures can be provided to encourage farms to implement biogas recovery projects.
Education and training: Through education and training, the awareness and technical level of farm managers and dairy farmers on biogas recycling can be improved. You can improve the knowledge and skills of relevant personnel by organizing training courses and publishing publicity materials.
Cooperation and exchange: strengthen cooperation and exchange with international organizations and scientific research institutions, learn from the successful experience and technological achievements of other countries and regions, and promote the research and development and application of biogas recycling technology.
In a word, it is a challenging and potential job to collect and utilize methane in cow fart on a large scale and efficiently. By comprehensively applying various measures and technical means, this goal can be achieved, thus reducing the impact of dairy farming on the environment and promoting sustainable development.
