Animal husbandry is an important part of agricultural production and an important support for economic development. According to FAO data, the output value of global animal husbandry is expected to reach about 1.8 trillion USD by 2026. However, the rapid development of animal husbandry has led to problems such as excessive breeding density and overload of livestock and poultry waste on land in some areas, resulting in a sharp increase in environmental pollution risks.

Current status of livestock and poultry manure pollution

1. Soil pollution

Intensive and large-scale breeding models cause livestock and poultry manure emissions to exceed the soil carrying capacity, making it difficult to be absorbed in time. For example, excessive application of manure in farmland soil will cause the nitrogen, phosphorus and potassium content in the soil to exceed the standard, seriously inhibiting the growth of crops.

2. Air pollution

In large-scale farms, due to the large number of livestock and poultry breeding and concentrated breeding areas, the accumulated livestock and poultry manure will produce a large amount of toxic and harmful gases such as hydrogen sulfide after corruption and decomposition, which may endanger animal and even human health.

3. Water pollution

The water pollutants produced by livestock and poultry farming mainly include nitrogen, phosphorus and other substances. The sewage that seeps into the ground will greatly increase the concentration of nitrate nitrogen or nitrite nitrogen in the groundwater, reduce the dissolved oxygen content of the groundwater, and cause the groundwater quality to seriously deteriorate.

Solutions

1. Anaerobic fermentation

The organic matter content in livestock and poultry manure is 30%-70%, which is a very potential carbon source. Through anaerobic fermentation, these organic matters can be converted into clean energy such as methane and hydrogen. At the same time, the biogas slurry and biogas residue produced after fermentation are rich in beneficial microorganisms and nutrients such as nitrogen and phosphorus, which can be used as soil organic fertilizer. Therefore, anaerobic fermentation is an effective treatment method that can reduce livestock and poultry waste and realize the utilization of resources and energy.

2. Aerobic fermentation

Aerobic fermentation is a common technology for composting, which has strong harmless treatment capacity and economic benefits for manure. Through aerobic fermentation, microorganisms in the pile will degrade organic matter in the manure, generate high temperature, promote manure decomposition, kill pathogenic microorganisms and weed seeds, and finally form compounds and humus that are beneficial to plants. This method is widely used in livestock and poultry manure treatment and has high added value.

Comparison

Through data analysis, I think aerobic fermentation is more suitable for treating livestock and poultry manure than anaerobic fermentation.

First, the aerobic fermentation treatment cycle is short, which can quickly achieve the harmlessness of manure and sewage, and is suitable for the rapid treatment of large amounts of waste. Secondly, the high temperature generated by the fermentation process can effectively kill pathogenic microorganisms and weed seeds, and the product is safer. Thirdly, the final product of aerobic fermentation is humus-rich compost, which has high added value and can be used directly as an organic fertilizer, bringing better economic benefits.

The industrial fermentation tanks that have appeared and are widely used make full use of the high-temperature aerobic principle, solve a series of drawbacks of traditional composting, and efficiently transform livestock and poultry manure. Let me introduce an aerobic fermentation tank in detail.

Bolong High-Temperature Aerobic Fermentation Tank

Bolong Company has more than 30 years of experience in the breeding industry. In recent years, it has been paying attention to the production process of harmless livestock and poultry manure at home and abroad, and has introduced advanced technology and scientific and technological talents to create its own high-temperature aerobic fermentation tank.

Bolong's high-temperature aerobic fermentation tank can maximize the utilization of waste. It only takes seven days to convert livestock and poultry manure into high-quality organic fertilizer. As long as the moisture content of organic waste is kept below 70%, no auxiliary materials need to be added, and it can be directly put into the tank for aerobic fermentation.

Bolong has specially developed the gas deodorization system 5.0, which is specially designed to effectively remove the odor generated during the fermentation process. The system uses the characteristics of ammonia being easily soluble in water, and combines activated carbon and microbial deodorizing bacteria to absorb and decompose the odorous gases generated during the fermentation process. This system not only improves the sanitary conditions of the fermentation process, but also provides a more comfortable working environment for farms and related facilities.

Conclusion

In response to the challenges of livestock and poultry manure pollution, Bolong's high-temperature aerobic fermentation tank has demonstrated its excellent solution. The fermentation tank uses advanced high-temperature aerobic technology to efficiently convert livestock and poultry manure and significantly reduce the emission of odor and harmful gases.
